The CFM/CMM Thermo Anemometer with InfraRed Thermometer measures remote surface temperatures to 260°C (500°F) with 8:1 distance to spot ratio, Air Velocity, Air Flow (volume), Air Temperature (with probe) and Surface Temperature (with the InfraRed function). The large, easy-to-read backlit LCD includes primary and secondary displays plus numerous status indicators. The InfraRed feature includes a laser pointer for convenient targeting. In addition, the meter can store 16 area setting dimension for easy recall. Excellent for ventilation surveys, air conditioning, heating and environmental monitoring.
