Extech 42512-NIST Dual Laser Infrared Thermometer, 1 Data Memory Recall Count, 0.35lbs. NIST Cert. This dual laser Infrared thermometer identifies the exact measuring spot when the two lasers converge to a single spot at approximately 30 In. from the target. Adjustable emissivity increases measurement accuracy for different surfaces. Adjustable high/low set points with audible alarm alerts you when temperature exceeds the programmed set points. Comes complete with carrying case, battery and NIST Certificate.

Extech AN310-NIST CFM/CMM Anemometer/Anemometer, Green NIST Certified Extech's 4 In. (10 cm) large vane thermo-anemometer series allows for more precise readings on larger size ducts. Each meter simultaneously displays airflow or air velocity and temperature. Model AN310 also measures relative humidity, wet bulb and dew point. Comes with NIST Certificate.
