Description
The Testo 622 thermo hygrometer and barometer is a high-precision multi-functional instrument engineered for simultaneous, at-a-glance monitoring of air temperature, relative humidity, and absolute air pressure. Performing updates at an efficient 10-second measuring rate, it displays current readings alongside time and date on a large, prominent LCD display. The device is outfitted with a highly efficient visual LED alarm that flashes to alert occupants immediately if configured environmental safety thresholds are violated. Complete with versatile wall and table mounts, it guarantees reliable long-term operations.
