PCE-HVAC 3 multifunction hygrometer
Measures relative humidity (% RH) and ambient temperature (°C / °F) / Calculates dew point and wet bulb temperatures (°C / °F) / Features MIN, MAX, HOLD functions
The PCE-HVAC 3 measures relative humidity and ambient room temperature via built-in sensors and based on these measurements calculates dew point and wet bulb temperatures in Celsius (°C) and Fahrenheit (°F). It has a wide range of applications such as heating, ventilation, and air conditioning (HVAC) system control.
The ergonomic design and the illuminated LCD screen make operating the meter particularly easy. The PCE-HVAC 3 can be set to take measurements over a long period. The auto shut-off function can be disabled during this period, while it is possible to determine the extreme values (MIN, MAX) for a specific period within this interval. Additionally, it features a thread for tripod mounting.
- Ergonomic design / One-handed operation
- Large backlit LCD display
- MIN, MAX, HOLD functions
- The built-in sensors measure relative humidity and ambient temperature
- Calculation of dew point temperature and wet bulb temperature
- The automatic shutdown can be disabled for long-term measurement
