COMET U4440 | Temperature, Humidity, CO2 & Pressure Data Logger (Built-in Sensors)

All four parameters in one device — the COMET U4440 simultaneously records temperature, relative humidity, atmospheric pressure and CO2 concentration using built-in sensors. Suited to comprehensive indoor environment monitoring in offices, laboratories and controlled storage areas where a single compact logger is preferred over multiple individual instruments across the monitoring site.

Description

COMET U4440 Data logger 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.

Warranty: 3 years
