These lightweight and compact units offer IP 67 waterproof protection in a compact casing. The electrode has a built-in temperature sensor and amplifier, to safe guard your measurements to noise and electrical interference. The HA-991001 reads pH and temperature. HA-991003 is the first pH meter that can measure pH, pH-mV (to check the electrode status), ORP and temperature with only one probe.
HA-991001, and HA-991003 include HA-1296D pH electrode (HA-991001) or HA-1297D ( HA-991003), and internal temperature sensor, pH 4 and pH 7 buffer sachets, HA-700661 electrode cleaning solution (2 x 20 ml), 3 x 1.5 V "AA" batteries, rugged carrying case and instructions.
