HD300 Thermo Anemometer with IR Temperature

Built-in IR Thermometer measures non-contact surface temperature

Built-in IR Thermometer Measures non-contact surface temperatures of objects unsafe or difficult to reach
Extech HD300 CFM Thermo-Anemometer. This handheld meter measures and displays air velocity, air flow (volume), temperature of air, and surface temperature (using the built-in non-contact IR thermometer). This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
