Designed for measurement of oxygen dissolved in water and sewage in % or mg/l, oxygen saturation in 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 work efficiently 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 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.
