WATERPROOF OXYGEN METER CO-451


The most important features




Detailed description

Designed for measurement of oxygen dissolved in water and sewage in % or mg/l, oxygen saturation in the air and temperature. Simple and accurate field and laboratory meter.

Characteristic features:



The standard set includes COG-1 oxygen sensor and CT2B-121 temperature probe with Pt-1000B resistor. Contrary to the meters of 401 series the meter is not equipped with the pressure sensor.
