6 in 1 Digital Multimeter with Environment Measurement
The model 61 is 6 in 1 Digital Multimeter with Environment Measurement. It has been designed to combine the functions of Sound Level Meter, Light Meter, Humidity Meter, Temperature Meter  &Non-contact AC voltage detector.
The model 51 is without temperature (ºF) range. They are ideal Multifunction Environment & DMM Instruments with scores of practical applications for professional and home use.
The Sound Level function can be used to measure noise in factories, schools, offices and 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.
The DMM function include ACV, DCV, ACA, DCA Resistance, Capacitance, Frequency, Duty Cycle, Diode, Continuity test and Non-contact AC voltage detector.
