1. INTRODUCTION
• The 5-in-1 digital Multifunction Environment Meter has been designed to
combine the functions of Sound Level Meter, Light Meter, Humidity Meter
and 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 assessments.
2. FEATURES
1. Larger LCD display with backlight. MAX MIN and AVG measurements.
2. Display Sound, Light, Type-K Temperature, Humidity & Temperature plus
Air Velocity & Air Flow simultaneously.
3. Electronic Offset function allows compensation of thermocouple errors to
maximize overall accuracy.
4. The device measures air velocity, it features 5 selectable units of velocity
measure: mis, ft/min, km/h, MPH, knots. And it features 2 selectable
units of flow measure: CFM, CMM.
5. Easy to set Area dimension (up to 6 point) for air flow measurement.
6. USB interface, USB to UART Bridge Controller.
7. Low battery indication, and Auto Power Off mode (Sleep mode)
increases.
