Thermo- Anemometer with built-in non-contact IR Thermometer measures remote surface temperatures to 500°C (932°F) with 30:1 distance to spot ratio, air velocity, airflow volume and temperature. This velocity/volume thermo-anemometer is rich in functions with data hold, min/max hold, averaging and memory for area sizes. Excellent for ventilation surveys, air conditioning, heating and environmental monitoring.

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)
• 16 memory locations for area sizes (8 CFM, 8 CMM)
• °C/°F (switchable) temperature via a sensor in the centre of the vane
• Easy to set Area dimension (cm3) are saved in the meter’s internal memory
