sauermann CLASS 50 Portables Thermo-Anemometer User Guide
These portable instruments are used to measure the following parameters: temperature, relative humidity, CO, pressure, air velocity and light.
Operating temperature, protection of the instruments and information
about storage
Conditions of use (°C/%RH/m): from 0 to +50 °C. In non-condensing
conditions. From 0 to 2000 m. Protection: IP54
Storage temperature: HD 50, LX 50: from -20 to +70 °C. CT 50, CO 50, HM 50, LV 50, MP 50, MP 51, MP 55, VT 50: from -20 to +80 °C. If the instrument is stored outside the operating temperature (for example in a van, a warehouse…), please wait for 10 minutes in its operating temperature before start using it.

Take a measurement
VT 50: before using the instrument with the hot wire probe, please lower
the protection tube (1) of the sensing element.
VT 50: always use the hot wire probe with the red point in front of flow.
Switch on the instrument by pressing briefly on “On/Off/Hold”.
The instrument displays its name then the measurement.
CO 50: the instrument displays its name then a 5 second countdown. This count corresponds to the preheating time of the sensor. At the end of the countdown, the measured value of CO is displayed.
MP 50, MP 51: the instrument displays its name then an autozero is performed. At the end of the autozero, the measured value displays.
Press briefly on “Select” to switch measurement parameter display.
MP 50, MP 51, MP 55: press briefly and successively on “Select” to change the unit.
- Available units for MP 50: Pa, mmH2 0, inWg, daPa.
- Available units for MP 51: mmH2 0, kPa, in Wg, mbar, mmHg, daPa.
- Available units for MP 55: mbar, mmHg, hPa.
HM 50: press briefly on “Select” to select a type of material.
Press the spikes in the material to be measured. When a measurement is over-
range, above the maximum range, the value flashes. Below the minimum range,
the value is no more measurable and the device indicates “—“, it means that
for:
- Wood type 1: the measurement is < than 10%
- Wood type 2: the measurement is < than 9%
- Plaster, brick and concrete: the measurement is < than 0.1%
Carry out a manual autozero (MP 50, MP 51)
During measurement:
Remove pressure tubes. Carry out a long press on “Select”.
The instrument makes an autozero then returns to the measurement display.
Hold the measurement
During measurement, press briefly on “On/Off/Hold” to hold measurement: “Hold” appears on the screen and measurements are fixed.

velocity (“Optic”).
Carry out a long press on “Select” to confirm.
Perform a self-test (HM 50)
Turn the instrument on. Remove the cap and turn the cap.Press “Select” to select the type of material to verify. Press the 2 pins of the instrument into the contact plugs of the cap. Read the value indicated by the instrument:
- If the indicated value matches with the given value in the table below, the instrument runs properly.
- If the indicated value does not match with the given value in the table below, clean the tips and carry out a new self-test. If the value is still wrong, change the pins. If it does not work, please contact the after sales service.
