HOT WIRE ANEMOMETER
Model : AM-4204HA
* 0.2 – 20.0 m/s, high precision for low air velocity measurement.
* m/s, ft/min, km/h, knots, mile/h, oC/oF.
* Max., Min., Data hold.
* Telescope probe.
* Size : 185 x 78 x 38 mm.

FEATURES
* Thermal anemometer, available for very lowair velocity measurement. * The portable anemometer provides fast, accuratereadings, with digital readability and theconvenience of a remote probe separately.
* Slim probe, ideal for grilles & diffusers.
* Combination of hot wire and standardthermistor, deliver rapid and precisemeasurements even at low air velocity value. * Multi-functions for air flow measurement :

m/s, km/h, ft/min, knots. mile/h.

* Build in temperature  ℃, ℉ measurement.
* Microprocessor circuit assures maximumpossible accuracy, provides special functionsand features. * Thermistor sensor for Temp. measurement, fastresponse time.
* Used the durable, long-lasting components,including a strong, light weight ABS-plastichousing case.
* Super large LCD with dual function meter’sdisplay, read the air velocity & temp. at thesame time.
