3. Introduction The instrument WMS-LTC is a device designed and assembled by PASI srl. The WMS-LTC is a conductivity, temperature and level meter. The instrument is equipped with a display on which the temperature and conductivity indications are shown. The water level will be visible on the cable marked in centimetres.

The detection of the water level may be inaccurate due to the formation of water residues on the probe after extracting it from the water. For this reason the WMS-LTC is equipped with an automatic level detection system. When there is high conductivities, however, manual selection of sensitivity may be more effective.
Maintenance To keep your instrument in perfect condition, remember to carefully clean the cable and sensor and dry them with a soft cloth after use. WMS-LTC...

To clean the probe it is recommended to use denatured ethyl alcohol and then rinse it in distilled water. This procedure is very important to get an accurate reading.
Take a measurement 6. Take a measurement The use of the WMS-LTC instrument is very easy. After switching on the instrument, the conductivity, temperature and level can be read. The probe has a certain thermal inertia and to obtain an accurate reading of conductivity and temperature it is necessary to leave the probe immersed for at least 5 minutes.
