摘要:
QDF係列熱球式電風速計
該係列產品為經濟型,其價格低,適合少投資、不經常使用,但又必須裝備的企事業單位。
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、空調製冷、環境保護、節能監測、氣象、農業、冷藏、幹燥、衛生防疫、**控製、勞動衛生調查、潔淨車間、化纖紡織,各種風速實驗等方麵有廣泛用途。
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.
