The CEM DT-618 is a portable thermo anemometer designed to measure both air velocity and air temperature in ventilation systems, air conditioning units, cleanrooms, industrial facilities, and environmental monitoring applications. The remote vane probe enables convenient measurements in ducts and hard-to-reach locations while maintaining measurement accuracy.
Unlike the DT-618B and higher models, the standard DT-618 focuses on air velocity and temperature measurement without additional airflow calculation functions, making it a cost-effective solution for technicians who require reliable wind speed and temperature monitoring. The instrument includes MAX hold, data hold, backlight, and automatic power-off functions for everyday professional use.
