Overview

The RKI AirLink 6900 is a battery powered, explosion proof wireless gas detector transmitter. It takes one electrochemical, PID or low-power infrared sensor and reports to an RKI AirLink controller by 900 MHz or 2.4 GHz radio, with no power or signal wiring.

  • Wire free: two 3.6 V lithium-thionyl chloride batteries (38 Ah total) and a wireless radio
  • Battery life up to 2 years with electrochemical sensors, 1 year with low-power infrared, 14+ days with PID
  • One sensor: electrochemical toxics and O2, low-power infrared LEL or CO2, or PID for VOCs
  • 900 MHz or 2.4 GHz radio, 1 to 1.5 miles range, 255 addresses per network
  • Sunlight readable 102 x 64 graphic LCD with LED backlight
  • Magnetic switches for non-intrusive calibration, settings and diagnostics
  • CQPSUS explosion / flame proof Class I Div 1 and 2 Groups B C D (certification for select gases)
  • Optional remote sensor kit: up to 250 ft (electrochemical and PID) or 40 ft (low-power infrared)
  • Reports to the AirLink 7010 and AirLink 7032 controllers

Built to order: choose the sensor (gas and range), the 900 MHz or 2.4 GHz radio and the optional remote sensor kit. Request a quote for pricing and availability.
