COMET U4440 Temperature, humidity, CO2 and atmospheric pressure data logger with built-in sensors
Quantity
Product Details
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.
