WATERPROOF THERMO / HYGROMETER PWT-411


PWT-411 is used for accurate relative air humidity and temperature measurements and dew point determining, what enables deciding whether painting the surface is advisable in existing conditions.
The measurement is made with a sensor of high accuracy connected with a meter by a cable.
