LEGACY MODEL- New Model available SCA
The M1000 Dissolved Oxygen Analyser is a digital instrument designed for the continuous monitoring of dissolved oxygen in water and 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 analyser provide a high degree of flexibility and ease of use. Calibration is not required on a routine basis, nor is calibration required after initial start-up and commissioning.
Two isolated analogue outputs are standard. Three programmable set-point relays and one relay to control self-cleaning are also standard.
The sensor to be used with this analyser is an optical type sensor that measures the fluorescence and quenching reactions of a ruthenium complex that is immobilised in a sol-gel matrix.
