The CEM DT-8820 is a 4 in 1 digital Multifunction Environment Meter . It has been designed to combine the functions of a 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 luminance 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 use a humidity/semiconductor sensor and K type thermocouple.4 in 1 Multi-function environment meter is a cost-effective introduction to aid conformance to health and safety in the work place. It measures Sound Levels, Light Levels, Humidity (%RH) and Temperature. The LCD display has large digits and function indicators.
