QDF-3熱球式電風速計,熱線式風速儀該系列產(chǎn)品為經(jīng)濟型,其價格低,適合少投資、不經(jīng)常使用,但又必須裝備的企事業(yè)單位。熱球式電風速計是以測量風速為基本功能的便攜式低風速測量儀表,尤其適用測量微風,在測量管道風速及采暖、空調(diào)制冷、環(huán)境保護、節(jié)能監(jiān)測、氣象、農(nóng)業(yè)、冷藏、干燥、衛(wèi)生防疫、疾病控制、勞動衛(wèi)生調(diào)查、潔凈車間、化纖紡織,各種風速實驗等方面有廣泛用途。
QDF Series Hot-bulb Wind Velocity Instrument
Its main feature is low price especially for those enterprises who must equip such device but with less investment and no often use.
It is a portable and intelligent instrument mainly for low wind velocity, combined with the function for the measurement of wind temperature and relative humidity. It is widely used in pipeline environment, heating, refrigeration, environment protection, energy monitor, weather, textile industry and kinds of wind velocity experiment, etc.
