4 in 1 Multi-Function Environment Meter which has been designed to combine the functions of sound level meter, light meter, humidity meter and thermometer and is ideally suited to a variety of practical applications for professional and home use.

The sound level function can be used to measure noise in factories, schools, offices, airports, 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 avery stable, long life, silicon diode.

The humidity/ temperature is taken by a semi-conductor sensor and K type thermocouple.
