SPECIFICATIONS TESTO 425 THERMAL ANEMOMETER WITH FLOW PROBE spec máy đo tốc độ gió Testo 425
In order to establish whether an air conditioning or ventilation system is functioning properly, among other things you need to check the flow speed or the volumetric flow in the ventilation duct. If the air flow velocity is too low, the room loads are not correctly discharged and optimum room air quality can no longer be guaranteed.

1. Testo 425 thermal anemometer for quick, easy flow measurement

The testo 425 thermal anemometer enables quick spot measurements in ventilation ducts. It records the flow speed, calculates the volumetric flow and also measures the temperature. With a measuring range of 0 to +20 m/s, the anemometer is particularly well suited to low air flow velocity.

2. Testo 425 owns a smart probe design

Testo 425 has a smart probe design. The thermal anemometer features a telescopic flow probe. The telescope can be extended to a length of up to 820 mm and has a probe head diameter of 7.5 mm.

3. Can detect the volumetric flow on your air conditioning or ventilation

It can detect the volumetric flow on your air conditioning or ventilation. When you input the duct surface area, it automatically calculates the volumetric flow during the flow measurement. Single and multi-point averaging provides an indicator of the average volumetric flow, flow speed and temperature reading.

4. You can read off the current readings and the min/max

Model 425 of Testo allows you to read the current readings and the min/max and calculated mean value at any time on the illuminated display. Using the Hold button, you can freeze the current reading in order to compare it with another value, for example. If you should ever forget to switch off the anemometer, the Auto-off function will take care of this for you. This conserves your batteries and ensures that your thermal anemometer is ready for use in the next measurement.
