- Model M1000 - Dissolved Oxygen Analyzer (Single Channel)



The Model M1000 dissolved oxygen analyzer is a unique system that combines advanced electronics with a solid-state optical sensor. No other dissolved oxygen system can compare with the features and benefits of this revolutionary design. The Model 10 sensor utilizes an optical technique that does not consume oxygen like all standard membrane sensors.

The Model M1000 Dissolved Oxygen Analyzer is a digital instrument designed for the continuous monitoring of dissolved oxygen in wastewater where parts per million accuracy is required. The instrument is designed to be used with the Model 10 sensor. The unit will display dissolved oxygen content in 0.01 ppm resolution over a range of 0.00 to 3.99 ppm and 0.1 ppm resolution over a range of 4.0 to 20.0 ppm. Temperature is displayed in 0.1 degree Celsius increments over a 0.0 to 50.0 degree Celsius range or 1 degree Fahrenheit increments over a 32 to 122 degree Fahrenheit range.The microprocessor based electronics of the Model 1000 analyzer provide a high degree of flexibility and ease of use. Calibration is not required on a routine basis, nor is calibration required after initial startup and commissioning.

Two isolated analog outputs are standard. Three programmable set-point relays and one additional relay to control self-cleaning are also standard. The sensor to be used with this analyzer is an optical type sensor that measures the fluorescence and quenching reactions of a ruthenium complex that is immobilized in a sol-gel matrix.
