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:

Colour, graphic touchscreen - enables simultaneous readout of the oxygen and temperature value.
Used for field and laboratory work.
Low weight and small size make working in the field easier.
Long lasting work in laboratory possible with use of the power adapter.
Waterproof housing (IP-66) enables work in difficult conditions.
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.
Memory of 200 results with time and date.
Calibration time reminding.
Powered by rechargeable batteries or power adapter.
Available 7 different languages: english, german, french, spanish, portuguese, italian, polish.
Automatic switch off function.
Delivered in the set COG-1 easy-in-use, accurate galvanic oxygen sensor with 1 m cable.
When properly maintained, the sensor may work efficiently for several years.
24 months of warranty for the meter.
The standard set includes the oxygen sensor, oxygen sensor equipment, temperature sensor with a built in PT-1000b resistor, power adapter and protective case for the meter and accessories.

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.

*	The accuracy of the meter only.
**	The accuracy of the meter only. With COG-1 or COG-2 oxygen sensor the accuracy at calibration temperature: ±2 %. By the difference ±5 °C accuracy: ± 3 %, by the difference ±10 °C accuracy: ±5 %.
***	The accuracy of the meter only. The total error includes the meters and probe’s accuracy. In the range 0 ÷ 100 °C the acceptable error of the probe with Pt-1000B resistor: ±0.8 °C, with Pt-1000A resistor: ±0.35 °C.
