CEM DT-8820 4 in 1 Multifunction Environment Meter


  • Multifunction Environment Meter 
  • Brand: CEM
  • Model: DT-8820
  • Country of Origin: Taiwan


The 4 in 1 digital Multifunction Environment Meter has been designed to combine the

functions of Sound Level Meter, Light Meter, Humidity Meter, and Temperature Meter. It is

an ideal Multifunction Environment Meter Instrument with scores of practical applications

for professional and home use.

The Sound Level function can be used to measure noise in factories, schools, offices,

home, etc, checking acoustics of studios, auditoriums and hi-fi installations.

The Light function is used to measure illuminance in the field. It is fully cosine corrected

for the angular incidence of light. The light sensitive component used in the meter is a very

stable, long life silicon diode.

The Humidity/Temperature uses a humidity/semiconductor sensor and K type thermocouple.
