Integrated temperature measurement and absolute pressure compensation for accurate measurement results

Maximum precision for measuring flow in laboratory fume cupboards according to DIN EN 14175-3/-4

Intelligent calibration concept

Flow measuring range: 0 to +5 m/s

Use the hot wire probe (thermal anemometer) to determine flow velocity and volume flow in laboratory fume cupboards. It is particularly suitable for low flow velocities up to +5 m/s. One of its most impressive features is its ultimate precision. Measurement of inflow speed and integrated calculation of volume flow produce quick results. The probe can also measure temperatures up to +50 °C at the same time.

The hot wire probe is equipped with a telescope, which can be extended to a maximum length of 730 mm. Use of the telescope enables the sash opening to be kept as clear as possible, so that the flow velocity is not affected.

One particularly practical feature is the fact that the probe can be changed while the measuring instrument is switched on.

Intelligent calibration concept

The probe offers maximum digital measurement reliability. The digital probe allows readings to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. The probe can be returned on its own (without the measuring instrument) for calibration. Calculating the determined calibration data in the probe generates a zero-error display.
