Greisinger Air humidity meter (hygrometer) GMH 3351 0 % rH 100 Data logger function

The interchangeable sensors can be replaced without recalibration, as they store their calibration data in an integrated memory or can be swapped out due to their high mechanical precision. The thermocouple input T2 is optimized for quickly capturing surface temperatures, allowing for direct display of the dew point distance, for example. Applications include heating, ventilation, and air conditioning (HVAC), indoor air quality, meteorology, laboratories, research and teaching, energy assessment, and building optimization, as well as investigating the causes of construction damage.
