The VOLTCRAFT UM5/1 200 is the all-round environmental measuring device. It combines with everything in one device (Sound level meter, Light meter, Humidity meter, Temperature meter, Dew point measurement and CFM/CMM Thermo-Anemometer). The multifunction Environment Meter is ideal for practical applications at professional and home use.The Sound Level meterThe sound level meter can be used to measure noise in factories, schools, offices, homes...etc.The Light meterThe light meter is used to measure luminance in the field. It is fully cosine corrected for the angular incidence of light.The Humidity / Temperature meterThe humidity meter uses a semiconductor sensor and Temperature meter. It uses the Type-K thermocouple.The CFM/CMM Thermo-AnemometerThe Thermo-Anemometer is suitable for use in a wide variety of applications, including plant maintenance operations, environmental analysis, fume hood testing, and HVAC system assessments.USB interfaceThe meters measured data transfer to the computer via a USB interface (USB to UART Bridge Controller). The data displays and saves through PC software.
