1 PC Gas Flow Sensor FR20
FR20 gas flow sensor uses MEMS thermal principle to monitor the flow of pipeline gas medium, which is suitable for ventilator/anesthesia machine use in medical field/industrial process detection. Application Widely used to measure non-corrosive, non-strong acid and strong alkali gases in industrial process control, dust particles counter, automated control, medical equipment, portable instruments, air quality sampling, intelligent building and environmental monitoring equipment. Air samplers/analyzers/anesthetics/gas leak detectors/environmental air monitor/particle counters/Lighter fire automatic adjustment equipment/gas chromatography... Features High sensitivity, very low starting flow; High response speed; High accuracy and repeatability; Low pressure loss; Modular structure design.
