The CFM/CMM Thermo Anemometer instrument measures Air Velocity, Air Flow (volume) and Temperature. The large, easy-to-read backlit LCD includes primary and secondary displays plus numerous status indicators. The meter is shipped fully tested and calibrated and with proper use will provide years of reliable service.

FEATURES

• Supper large LCD backlit display with large digits and function indicators
• Simultaneous display of air flow or air velocity plus ambient temperature
• Measures air velocity in m/s, ft/min, km/h, knots & mph
• Measures volume in m³/min (CMM) & ft³/min (CFM)
• Average multiple readings for velocity or flow volume for up to 20 readings
• Volume measurements by entering the area of the duct or grille being measured
• 16 memory locations for area sizes (8 CFM, 8 CMM)
• Easy to set Area dimension (cm3) are saved in the meter’s internal memory
• °C/°F (switchable) temperature via a sensor in the centre of the vane
• Resolution of 0.01m/second
• Data Hold & Max/Min functions
• Data Hold & Max/Min Hold for temperature
• Max/Min Memory: record and view maximum and minimum readings
• Automatic power off and low battery indication
• Standard ¼" camera bush for tripod mounting
