摘要:
QDF系列熱球式電風(fēng)速計(jì)
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(cè)量風(fēng)速為基本功能的便攜式低風(fēng)速測(cè)量儀表,尤其適用測(cè)量微風(fēng),在測(cè)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(cè)、氣象、農(nóng)業(yè)、冷藏、干燥、衛(wèi)生防疫、**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 SeriesHot-bulb Wind Velocity Instrument
Its main feature is low price especially for those enterpriseswho must equip such device but with less investment and no oftenuse.
It is a portable and intelligent instrument mainly for lowwind velocity, combined with the function for the measurement ofwind temperature and relative humidity. It is widely used inpipeline environment, heating, refrigeration, environmentprotection, energy monitor, weather, textile industry and kinds ofwind velocity experiment, etc.
