WATERPROOF OXYGEN METER CO-411

The most important features

Measures oxygen dissolved in water in % and mg/l, oxygen in the air in % and temperature.
The display enables simultaneous readout of the measured function and temperature.
Calibration in 1 or 2 points (0 and 100%).
Possibility of entering the salinity value which influences the dissolved oxygen concentration measured in mg/l.
Small size and weight.
Waterproof housing.
Memory of 50 results
No PC connection.

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:

Low weight and small size make working in the field easier.
Waterproof housing (IP-66) facilitates working in difficult conditions.
Easy in use galvanic oxygen sensor on about 1 m cable. When properly maintained, the sensor may be efficient for several years.
1 or 2 point oxygen sensor calibration (at 0 % and 100 %).
Automatic temperature compensation.
Enables entering manually the values of air pressure and salinity for automatic correction of their influence on the result of oxygen concentration in the water or sewage measured in mg/l. CCO-401 and other multifunction meters enable entering these values automatically.
Memory of 50 results.
Possibility to determine the purity of industrial oxygen.
Automatic switch off function.
24 months of warranty for the meter.

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.
