?Hot wire anemometerhot wire Description:Air velocity transmitter series are designed for high accuracy measurement of lowest air velocities. It is the ideal solution for laminar flow control and special ventilation applications. The design with the ceramic substrates is fruitful to avoid chip corrosion. The design of mini air velocity sensor is for the narrow space,it shows a perfect integration about senosr and transmitter in a probe with 180mm length.The thin film sensor guarrantees accidental accuracy with low power consumption.high-precision,small dimension.It could be used in hand-held device.For HVAC, Ventilation, Air-condition, Purification room, Lab, Purification Workshop.hot wire specification:unitrangeresolutionaccuracyM/s0.1~25m/s0.01m/s+/-5% of reading +/-0.1m/sKm/h0.3~90km/h0.1km/h+/-5% of reading +/-0.1km/hFt/min20~4925ft/min1ft/min+/-5% of reading +/-0.1ft/minmph0.2~55.8mph0.1mph+/-5% of reading +/-0.1mphknots0.2~48.5knots0.1knots+/-5% of reading +/-0.1knotsAir temperature0~50C(32~122F)0.1C/F+/-1C(1.8F)CFM0~99999 ft33/min0.001~100CMM0~99999 m3/min0.001~100Sampling rate0.8SOperating temperature-0~50C(32~122F)Operating humidity<80%RHPower supply6F 22 9VadapterDC 9V 1Aweight310gsize185x66x33mm hot wire anemometer features:1:c/f temperature selectable.2:measures air velocity in m/sec.ft/min.km/sec.knots or mph.3:measures volume in CMM/CFM.4:55mm hi-contrast LCD display with backlight and function indicators.5:dual display for velocity and temperature.6:12 segment bargraph for velocity.7:average multiple readings for velocity or flow volume for the last 30 readings.8:auto power off.9:low battery indication.
