Renting an environmental monitoring instrument makes sense when a project needs a specific measurement for a fixed window — a two-week indoor air quality (IAQ) study, a landfill gas survey, or a groundwater sampling program — and buying the unit outright would sit idle the other 50 weeks of the year. ERE Inc. maintains a calibrated rental fleet covering IAQ monitors, particle counters, multiparameter water quality meters, water level meters, and landfill gas analyzers, in addition to the portable gas detectors already covered in our gas detector rental guide.

When Does Renting Beat Buying for Environmental Monitoring?
Renting wins when the measurement is tied to a project, not an ongoing operation: a Phase II ESA groundwater program, a post-renovation IAQ verification, a landfill gas migration check ahead of a regulatory filing, or a one-off particulate survey for an occupational hygiene report. A $6,000–$15,000 instrument that gets used for three weeks a year is a capital expense with a poor return; the same instrument rented for those three weeks is a line item on the project budget.
Buying makes more sense once utilization climbs — consultants running the same test monthly, facilities with a standing IAQ or water-monitoring program, or contractors who need an instrument on more sites than not. ERE sells every instrument in this guide outright as well as renting it, so the calculation can flip mid-project if a short-term need turns into a recurring one.
Which Environmental Monitoring Instruments Can You Rent From ERE?
ERE's rental-featured fleet covers six instrument families outside of gas detection, each available for short-term rental with current calibration. The table below maps the instrument to the parameter it measures and the project type it typically serves.
| Instrument | Vendor | Measures | Typical rental use |
|---|---|---|---|
| HI9829 Multiparameter Water Quality Meter | Hanna Instruments | pH, ORP, DO, EC/TDS, turbidity, temperature | Groundwater/surface water monitoring, regulatory field programs |
| Q-Trak™ 7575 IAQ Monitor | TSI | CO₂, CO, temperature, relative humidity | IAQ investigations, building commissioning |
| DustTrak™ II Aerosol Monitor 8532 | TSI | PM1, PM2.5, respirable, PM10 mass concentration | Occupational hygiene surveys, construction dust monitoring |
| Aerocet 532 Handheld Particle Monitor | Met One Instruments | Particle mass and count, PM1–PM10 and TSP | Cleanroom checks, indoor air quality screening |
| Water Tape (Series 1902) Water Level Meter | Heron Instruments | Depth to water in wells and boreholes | Groundwater monitoring networks, drawdown testing |
| GEM™5000 Landfill Gas Analyzer | QED (LANDTEC) | CH₄, CO₂, O₂, static/differential pressure | Landfill gas collection system monitoring, migration surveys |
For groundwater and surface water sample collection to pair with any of the above, see the EzyFlow™ Water Sampling Pump or ERE's full instrument rental collection.
Can You Rent a Multiparameter Water Quality Meter in Canada?
Yes — the Hanna HI9829 is ERE's standard rental for field water quality programs and is available across Canada. It measures up to 14 parameters through a single IP68-rated submersible probe, including pH, ORP, dissolved oxygen, conductivity/TDS, turbidity, and temperature, and logs up to 44,000 samples with up to 140 hours of battery life.
Consultants running CCME Canadian Environmental Quality Guideline–referenced groundwater or surface water monitoring programs use this instrument because a single probe replaces what would otherwise require three or four separate meters, cutting field time and the number of instruments that need separate calibration checks. Cable lengths run from 4 m to 20 m, and an autonomous-logging configuration is available for unattended deployment between site visits.
Which Rental Fits Your Air Quality Program — IAQ Monitor or Particle Counter?
Match the instrument to the parameter the project actually needs to report: CO₂/CO/humidity call for an IAQ monitor, particulate mass or count calls for an aerosol monitor or particle counter.
Indoor air quality investigations
The TSI Q-Trak™ 7575 simultaneously displays CO₂, CO, temperature, and relative humidity, logs up to 39 days of data at one-minute intervals, and is the instrument most often specified for the kind of building-performance verification Health Canada describes in its Residential Indoor Air Quality Guidelines. Renting it for a defined commissioning or complaint-investigation window avoids the cost of owning a probe-based instrument used only a handful of times a year.
Particulate and dust monitoring
For airborne particulate rather than gas-phase parameters, ERE rents two instruments depending on the reporting need. The TSI DustTrak™ II 8532 is a laser photometer reading real-time aerosol mass concentration from 0.001 to 150 mg/m³ across PM1, PM2.5, respirable, and PM10 fractions — the standard choice for occupational hygiene surveys that need a defensible mass-concentration number. The Met One Aerocet 532 instead reports both particle mass and particle count across an 8-channel, 0.3–10 micron range, which suits cleanroom verification and general IAQ screening where a count-based reading is more useful than mass alone. Both fit the kind of workplace investigation CCOHS's indoor air quality guidance describes for diagnosing occupant complaints.
Do You Need a Landfill Gas Analyzer Rental or a Portable Gas Detector?
Rent the GEM™5000 for landfill-specific gas composition work, and rent a portable multi-gas detector for confined-space entry or general workplace atmosphere monitoring — the two instruments serve different jobs and are not interchangeable.
The GEM™5000 is purpose-built to sample and analyze methane, carbon dioxide, and oxygen content in landfill gas collection and control systems, and calculates balance gas, flow, and calorific value in the same reading — figures a general-purpose gas detector cannot produce. It's calibrated to ISO/IEC 17025, certified intrinsically safe for landfill use, and carries a 3-year warranty. If the project instead calls for confined-space entry monitoring, area gas detection, or a portable multi-gas unit for general site safety, see ERE's dedicated gas detector rental guide and the portable gas detector collection.
Is a Water Level Meter Rental Worth It for a Short Field Program?
Yes for a one-off or infrequent monitoring network — the Heron Water Tape (Series 1902) is a low-cost instrument to begin with, so renting only makes sense when a project needs several units at once (multi-well monitoring rounds) or needs a longer tape length (150 m–300 m) than what's already on hand.
The Water Tape measures depth to water in wells and boreholes using a 5/8" IP68-rated field-replaceable probe and an audible/visual detection panel, with PFAS-free polyethylene tape available in lengths from 30 m to 300 m. For drawdown testing to calculate well production, renting a second or third unit for the monitoring round is usually cheaper than buying extras that sit unused between programs.
What Should an Instrument Rental Quote Include?
A complete instrument rental quote should specify the calibration certificate date, the rental period and any daily-rate breakpoints, what's included in the case (cables, probes, batteries, software), and who covers loss or damage. Confirm these five items before the unit ships:
- Calibration certificate — dated within the manufacturer's recommended interval, not just "calibrated at some point"
- Rental period and rate structure — daily vs. weekly rate, and what happens if the project runs long
- Included accessories — probes, cables, carrying case, software, and consumables (filters, batteries)
- Damage and loss terms — what's covered if the instrument is damaged on site
- Return logistics — pickup vs. drop-ship, and who arranges return freight
How Do You Request an Instrument Rental From ERE?
Requesting a rental takes three steps: tell ERE the instrument and dates, confirm availability and calibration, then receive the unit ready to deploy.
- Specify the instrument, dates, and site conditions. Name the parameter you need to measure (or the instrument model if you already know it) and the start/end dates for the rental window.
- Confirm availability and calibration. ERE checks the unit's calibration status and confirms shipping or pickup timing against your project start date.
- Receive the unit and return it after your monitoring window closes. The instrument ships or is ready for pickup with its calibration certificate and full accessory kit; return it using the pre-arranged logistics once the field work is done.
For a full breakdown of what's available, browse ERE's instrument rental collection, or request a quote with the instrument and dates you need.

Frequently Asked Questions
What's the difference between renting and buying an environmental monitoring instrument?
Renting covers a defined project window without tying up capital in an instrument that sits idle most of the year; buying makes sense once an instrument is used often enough that ownership costs less than repeated rental fees. ERE sells and rents every instrument in this guide, so the choice can change mid-project.
How long can I rent an instrument from ERE?
Rental periods are set per project — daily and weekly rates are available, and ERE confirms the return date and rate structure at quote time based on your field schedule.
Do rented instruments come pre-calibrated?
Yes. Every rental ships with a current calibration certificate, and ERE's own field service group checks the unit's calibration status before it leaves for a rental.
Can I rent a gas detector along with a water quality meter for the same project?
Yes — portable gas detectors are rented through the same process described in ERE's gas detector rental guide and can ship alongside any of the instruments covered here.
What happens if a rented instrument is damaged or malfunctions on site?
Damage and loss terms are confirmed on the rental quote before the unit ships — ask for this in writing at quote time so there's no ambiguity if something goes wrong in the field.
