รายละเอียด

4 in 1 digital Multifunction Environment Meter (Sound Level Meter, Light Meter, Humidity Meter, and Temperature Meter)

This Environment Test Meter measures Sound in dB, Light in Lux, Relative Humidity as %RH and Temperature in deg C or deg F

This popular hand held environment test meter is simple to operate has a large display and a few simple buttons to select the environment parameter to be measured.

The 4 in 1 Environment test meter has a data hold and max hold switch plus a low battery indication and it auto powers off to save batteries. The environment light sensor is on a coiled cable to enable the light level measurements to be made without the operator shading the light reading sensor. The plug in K type thermocouple enables this environment meter to measure temperature in degrees Celcius or Fahrenheit. This 4 in 1 Environment testing meter also has a 4mm camera bush for tripod mounting. Save money on buying individual testing instruments with this incredibly cheap 4 in 1 Environmental Meter.
