CEM DT-8894 CFM/CMM Thermo-Anemometer with IR Thermometer

Air flow and temperature measurement

The CEM DT-8894 is a CFM/CMM thermo-anemometer designed for professionals who need to measure air velocity, air flow and ambient temperature in ducts, vents and HVAC systems. A built-in non-contact infrared thermometer adds remote surface-temperature readings up to 500 ºC (932 ºF) with a 30:1 distance-to-spot ratio. The large 9999-count backlit LCD shows air flow or velocity together with ambient temperature simultaneously.

HVAC technicians and facility engineers

This instrument suits technicians who balance ventilation systems, commission ductwork or troubleshoot airflow distribution in commercial and industrial buildings. The 2.83 in (72 mm) ball-bearing vane on a 3.9 ft (120 cm) cable reaches into registers and grilles, while 20-point averaging and 0.01 m/s resolution support detailed traverse measurements. Users who require data logging, Bluetooth connectivity or a hot-wire probe for very low velocities should consider other models.

3 % velocity accuracy via 72 mm vane

The single specification that determines suitability is the stated 3 % velocity accuracy delivered by the low-friction 72 mm diameter ball-bearing vane wheel. This accuracy class, combined with the ability to store duct-area dimensions in memory for instant CFM/CMM read-out, decides whether the DT-8894 meets the verification or balancing tolerances required on a given job.
