General Description:       

     Widely used in data collection for boiler, refrigeration industry, ventilation duct, environment monitor, navigation measurement, weather forecast, collection of the weather datum for outdoor busywork and fire department.

* Wide applications: use to check air conditioning & heating systems , measure air velocity, wind speed, temperature, etc.

* Multifunctional. the measurement unit can be selected according to different requirements.

* Maximum value data hold function.

* DATA HOLD function for storing 24 groups of datas.

* Low-friction ball-bearing design allows free vane movement.

* Separate type design, convenient to measure.

* Automatic Power off, 0-9 minutes set by users.

* Use “USB data output” and “RS-232 data output” to connect with PC.

* Provide “Bluetooth ™ data output” choice.
