Dissolved Oxygen Meter (Extech)

Obtain and store up to 25 data sets of dissolved oxygen and temperature measurements with this waterproof meter. Oxygen level readings can be displayed as % saturation or concentration (mg/L [ppm]), and an analog bar graph indicates trends. The meter also features adjustable altitude compensation (0 to 20,000 ft. in 1,000 ft. increments), self-calibration, adjustable salinity compensation from 0 to 50 ppt, data hold, auto power off, and low battery indicator. Optional extension cables are available in 3 ft. (1m) or 16 ft. (5m) lengths. Waterproof to IP67. Meter comes complete with dissolved oxygen electrode, protective sensor cap, spare membrane cap, electrolyte, four 1.5V SR44W batteries, and a 48” neck strap. One year manufacturer’s warranty.
