AM-CDO Clark Cell Dissolved Oxygen Sensor

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

The AM-CDO is a traditional Clark cell style dissolved oxygen sensor that has been reengineered to provide accurate readings, long-life, stable output and easy maintenance. Although optically-based probes have become prevalent in wastewater monitoring, Clark style probes are simple, inexpensive, rugged and provide superior readings at very low dissolved oxygen concentrations.

The latest AM-CDO probe replaces the P91 probe and P91D cartridge. The new probe offers much longer lifetime and can be refurbished very easily by the user. The result is a lower cost of ownership than any electrochemical D.O. probe on the market.
The new 2250-1 controller replaces the legacy 2200D. However it can be used with old 2200D Controllers.
