The Velleman DVM401 Digital Environment Meter (Temp/Hum/dB/Lum)

Use this meter to find the exact conditions in your environment. With the ability to measure temperature, humidity, sound, and luminosity, the Velleman DVM401 delivers everything you need for a quick read on your surroundings. Reads are displayed on a 3.5 digit LCD display. Measure temperatures up to 1400°F and humidity up to 95%RH.

 

For sound measurements, chose between A and C weighted and Hi or Lo dB. When measuring sound, high winds may interfere with reads so use the included wind screen if using the DVM401 in a windy environment. When measuring light, simply hold the DVM401 meter horizontal to the light source. See our downloads tab for recommended illumination in various environments.

 

The Velleman DVM401 is a complete set that comes with battery (9V), temperature probe (K-type), humidity probe, photo detector, and carrying bag. DVM401 meter features also include auto power off and both data and maximum hold functions.
