Major Tech - MT941 5-In-1 Environmental Meter

The MT941 5-in-1 Environmental Meter has been designed to combine the functions of a Sound Level Meter, Light Meter, Humidity Meter, Temperature Meter and CFM/CMM Thermo-Anemometer. It is an ideal Multifunction Environment Meter 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 the 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. 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.

This Environmental Meter is carried in a hard plastic carrying case for convenience and protection.

Large LCD display with backlight
MAX, MIN and AVG measurements
Display shows Sound, Light, K-Type Temperature, Humidity & Temperature as well as Air Velocity & Air Flow
The Electronic Offset function allows compensation of thermocouple errors to maximize overall accuracy
The device measures air velocity, it features 5 selectable units of velocity measure: m/s, ft/min, km/h, MPH, and knots, and it features 2 selectable units of flow measure: CFM, CMM
Easy to set Area dimension (up to 6 points) for air flow measurement
USB interface, USB to UART Bridge Controller
Low battery indication, Auto Power Off (Sleep mode) adjustable
