Description

PCE Instruments Multifunction Thermometer (PCE-VA 20) is a professional-grade measuring device designed for precise assessment of environmental conditions. It measures air temperature, dew point, wet bulb temperature, relative humidity, air velocity, and volumetric airflow, making it ideal for HVAC maintenance, weather monitoring, and laboratory applications.

Additional functions such as max/min values, hold mode, and automatic shutoff enhance usability in field and industrial settings. Its compact design and battery-powered operation ensure portability for on-site analysis.
