Description

PCE-HVAC 3 Multifunction Hygrometer
Measures relative humidity (% RH) and ambient room temperature (°C / °F) / Calculates dew-point and wet-bulb temperatures (°C / °F) / Features hold and extreme value measurement functions

PCE-HVAC 3 is a multifunction hygrometer or diagnostic measuring device used for indoor climate and environmental monitoring. In addition to measuring relative humidity and ambient room / dry-bulb temperature, the meter calculates dew-point and wet-bulb temperatures in degrees Celsius (°C) and Fahrenheit (°F). Thus, heating, ventilation and air conditioning (HVAC) installations and HVAC system performance assessments are key applications of the PCE-HVAC 3 meter. Measurements of relative humidity and ambient room / dry-bulb temperature are made directly by built-in sensors. Dew-point and wet-bulb temperatures are calculated based on the measurement values transmitted ​​by the sensors.

Featuring a large, backlit display and six-button operation, the meter is both easy to read and easy to use. The meter is equipped to take one-time measurements on the spot as well as to monitor climate changes over time. The automatic shutdown function can be disabled when taking long-term measurements. There is also a thread on the back of the meter to allow the measuring instrument to be mounted on a tripod. The extreme value measurement function can be activated during long-term monitoring to determine the minimum or maximum values ​​over a desired period of time.

– Large backlit display
– One-handed operation
– Hold and extreme value functions
– Built-in sensors measure relative humidity and ambient room / dry-bulb temperature
– Dew-point temperature and wet-bulb temperature calculation
– Automatic shutdown can be disabled for long-term monitoring
