Popis
Handheld anemometers DwyerOmega are versatile and compact units that quickly and easily measure a variety of air quality standards in imperial or metric units. Model 471B-1 is provided with the Dwyer AP1 thermo anemometer probe and is able to measure air velocity or volumetric air flow, as well as air temperature. Model 473B-1 is provided with Dwyer VP1 (100 mm) vane thermo anemometer probe and is able to measure air velocity or volumetric air flow, as well as air temperature and humidity. Model 485B-1 is provided with Dwyer RP1 thermo hygrometer probe and is able to measure relative humidity and air temperature.
AP1, VP1, and RP1 probes are automatically recognized when plugged into the handheld, and can be interchanged without needing to adjust calibration.
Note: the lengths listed in the configurator are the lengths of the working part of the probe, the total length is greater.
