QDF-3指针热线式风速仪

详细信息

QDF-3热球式电风速计,QDF-3指针热线式风速仪该系列产品为经济型,其价格低,适合少投资、不经常使用,但又必须装备的企事业单位。热球式电风速计是以测量风速为基本功能的便携式低风速测量仪表,尤其适用测量微风,在测量管道风速及采暖、空调制冷、环境保护、节能监测、气象、农业、冷藏、干燥、卫生防疫、疾病控制、劳动卫生调查、洁净车间、化纤纺织,各种风速实验等方面有广泛用途。
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.
