Compact hot-wire anemometer Testo 425
Thermal anemometer compact Testo 425. Compact thermal anemometer with a telescopic handle with a permanently connected heated probe designed to measure air flow velocity and temperature. Thanks to the telescopic handle, the device is ideal for measuring flow speed in air ducts. The volume flow is shown directly on the display. The probe fits easily into the duct and provides accurate volume flow calculations. The operator can easily switch to display the current temperature readings. The averaging function over time and number of measurements allows you to obtain average values of volume flow, flow rate and temperature. The values are shown on the backlit display. The Hold function allows you to freeze the current measurement data on the display. Features: Measurement of temperature, speed and calculation of volumetric flow. Averaging measurement results over time and number of measurements. Displays maximum and minimum values. Hold function for displaying and fixing values on the display. Display backlight. Auto shut-off function. Scope of delivery: Thermal anemometer with a permanently connected heated wire probe. Telescopic handle (max. length 820 mm). Power supplies (batteries).
