Detailed description
CO-402 is designed for measuring trace oxygen concentration in % or mg/l and temperature in °C. The meter is used for measurements where the oxygen content has been reduced to minimal quantities – e.g. in heat and power plants, chemical or science laboratories. The meter cooperates with COG-1ts galvanic dissolved oxygen sensor and a special head for flow measurement.Characteristic features:
- It is characterised by high accuracy and stability of the measurements.
- ”HOLD” function to freeze the result on the display.
- Signalisation of the result stabilisation with the ”READY” symbol and a sound.
- Possibility of sending a calibration report to a PC - up to 10 last calibrations.
- It is equipped with easy to read backlit display what makes working easier.
- Automatic or manual temperature compensation.
- Software for data transmission and collection delivered in set.
- Sensor calibration in 2 points: 0 % and 100 % O 2 .
- Datalogger for 4000 data sets taken in series or individually with temperature, time and date.
- Non-volatile memory of the stored results and calibration data.
- Storing the date of next calibration and reminding it, in the right moment, to the user.
- Possibility of connecting with a PC by micro USB connector.
- Auto switch-off function after time set by the user.
- Waterproof housing facilitates working in difficult conditions.
- Powered by rechargeable batteries or power adapter with micro USB cable.
- Warranty for the meter: 24 months.
The measuring set includes:
-
1. CO-402 oxygen meter.
