Temperature, humidity, CO2 and atmospheric pressure data logger with built-in sensors
Datalogger is designed to record temperature, humidity, atmospheric pressure and CO2. In case of exceeded set limits alarms are indicated by LED, LCD and acoustically by built-in beeper.
The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via USB-C.
Recorder includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Optional CO₂ measuring range extension from the standard 0 to 5,000 ppm up to 0 to 10,000 ppm (available at extra cost):
- Extended measuring range: 0 to 10 000 ppm
- Accuracy in extended range: 100 ppm + 5% of the measured value at 25 °C and 1013 hPa
