Detail CEM DT-859B 5-in-1 Digital Multifunction Environment Meter


The digital Multifunction Environment Meter has been designed to combine the functions of Sound Level Meter, Light Meter, Humidity Meter Temperature Meter and CFM/CMM Thermo-Anemometer. 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 luminance 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 diode.
The Humidity/Temperature uses a humidity/semiconductor sensor and K type thermocouple.
CFM/CMM Thermo-Anemometer is suitable for use in a wide variety of applications, including plant maintenance operations, environmental analysis, fume hood testing, and HVAC system assessment

Larger LCD display with backlight.
Relative time clock on MAX MIN and AVG provides a time reference for measurement.
Display Sound, Light, Type K Temperature plus Humidity & Temperature simultaneously.
USB interface, USB to UART Bridge Controller..
Low battery indication, and Auto Power Off mode (Sleep mode) increases.
PC interface software for real-time measurement
