AM-ODO Optical Dissolved Oxygen Sensor from Aquametrix

USA Toll Free: 1-800-730-0302 Tel: 416-240-1920 -

AquaMetrix has been selling polarographic dissolved oxygen analyzers for over four decades.

We are pleased to be able to offer the only optical dissolved oxygen sensor that outputs directly 4-20 mA either for the %-saturation or concentration (mg/l or ppm) or concentration (mg/l or ppm) and temperature. It can connect to a PLC or the AquaMetrix 2300 controller. Optical DO sensors offer advantages over electrochemical DO sensors in that they are inherently self-referencing, require no warm-up period, do not require flow and are less affected by fouling.

Maintenance is trivial. The sensor membrane lasts for approximately 2 years and is inexpensive to replace. The body is corrosion resistant and designed to stand up to the harsh environment.

No sensor on the market packs as much into one small package at such an affordable price.
