Quest Technology Co., Ltd. Shenzhen Guo Sheng 15813896487 F900 airflow sensor is used to measure air velocity and temperature, can be used, for example, HVAC, industrial processes, automotive, air filtration systems, electronic enclosures and critical areas such as biological safety cabinets, ventilation cabinets and clean room applications. Depending on the setting, the standard airflow sensor range 0.15-2 m / s (30-400 fpm) to 0.15-10 m / s (30-2000 fpm), F900 series has a superior cost, compact size, reliability and against mechanical shock and vibration. F900 series based module has a linear 0-4V output or digital TTL output. F900 is easy to install and use. Sensor is equipped with an adjustable mounting bracket. In addition, F900 can choose any AccuSense remote sensor head. Features? Measuring air and inert gas velocity and temperature? Standard flow range 0.15-10 m / s between (approximately 30-2000 fpm)?
