Standard ST8820 4 in 1 Multifunction Environment Meter
4 in 1 Multifunction Environment Meter
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 idealMultifunction 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 uses a humidity/semiconductor sensor and K type thermocouple.
Standard ST8869 Professional Infrared Thermometer
8867H/8868/8868H/8869/8869H Series provide much faster, easier and accurate readings for most surface temperature measurements with Dual laser pointers. Two laser points converge to a single spot when the unit is at the optimal distance from the object being measured.
