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.

on / off LCD has a negligible effect on battery life, consumption is mainly determined by CO2 measurement, so I offer the following two variants:
measurement interval T, RH: 10 s
record interval: 10/15 min
For CO2 measurement interval: 2 min, the theoretical battery life is 160 days (without active optical and acoustic signaling)
For CO2 measurement interval: 10 min, the theoretical battery life is 24 months (without active optical and acoustic signaling)
