4 In 1 Multifuction Digital Environment Multimeter


 The MT941 is a 4 in 1 Environment Meter specially designed to combine the functions of Sound Level Meter, Light Meter, Humidity Meter and Thermometer. It is an ideal 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, 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 a very stable, long life silicone diode. The Temperature function measures the ambient temperature; the K-type input for temperature probes allows the MT941 to be a standalone thermometer.
