The 810-140 Therma-Hygrometer simultaneously displays both the humidity and temperature in addition to indicating and recording the maximum and minimum readings. Utilising the internal sensor the instrument measures temperature over the range of 0 to 50 °C. The external remote probe with integrated three metre lead measures both temperature and humidity over the range of -20 to 70 °C and 10 to 99 %rh. This therma-hygrometer is ideal for monitoring both temperature and humidity in rooms, offices, factories and similar to ensure optimum working conditions are maintained. The unit is housed in an ABS case, measuring 20 x 100 x 110 mm, that incorporates a useful foldaway stand and a keyhole slot for hanging on a wall.
