Model CO 411 -Waterproof Oxygen Meter

• 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.

• 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.
