Multifunction Environment Meter 5 in 1
The 5 in 1 digital Multifunction Environment Meter has been designed to combine the functions of Sound Level Meter, Light Meter, Humidity Meter, and Temperature Meter,wind speed 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 ciode. The Humidity/Temperature meter can measure the tempature and humidity of the air. The wind speed meter can measure the speed of the air
