CEM 5-in-1 digital Multifunction Environment Meter
(Model: DT-859B)
(Sound, Light, Air Flow, Humidity, and Temperature)

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, homes, 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

Features:

• Larger LCD display with backlight.
• The 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.
