DT-620 CFM/CMM Thermo Anemometer + InfraRed Thermometer
The CFM/CMM Thermo Anemometer with InfraRed Thermometer measures 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. Proper use of this meter will
Provide years of reliable service.
