Testo 0635 1543 Digital Thermal Flow Velocity Probe with Telescope

Use the Testo 0635 1543 Digital Thermal Flow Velocity Probe (thermal anemometer) to determine flow velocity and volume flow in ventilation ducts or at wall/ceiling outlets. It is particularly suitable for low and medium flow velocities up to 20 m/s. The probe can also measure temperature, humidity and absolute pressure simultaneously.

The 0635 1543 Digital Thermal Flow Velocity Probe is equipped with a robust, non-rotatable telescope, which can be extended to a maximum length of 3.6 ft. (1100 mm). The immersion depth is easy to read off thanks to the scaling on the telescope.

For easier handling, the probe can be bent up to an angle of 90 degrees. On the handle there is a practical measuring button, which activates storage of the readings. So you can fully focus on the positioning of the probe in the ventilation duct.

The 0635 1543 Digital Thermal Flow Velocity Probe offers maximum digital measurement reliability. The digital probe allows readings to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. Calculating the determined calibration data in the probe generates a zero-error display.
