QDF-3熱球式電風(fēng)速計(jì),熱線式風(fēng)速儀該系列產(chǎn)品為經(jīng)濟(jì)型,其價(jià)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(fēng)速計(jì)是以測量風(fēng)速為基本功能的便攜式低風(fēng)速測量儀表,尤其適用測量微風(fēng),在測量管道風(fēng)速及采暖、空調(diào)制冷、環(huán)境保護(hù)、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(dòng)衛(wèi)生調(diào)查、潔凈車間、化纖紡織,各種風(fēng)速實(shí)驗(yàn)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.
