This product specification is applied to the Humidity Sensor Type HCZ-H8. The terminal electrode
material uses lead free solder (Sn / Ag / Cu). This product is conformity with RoHS directive which
means that lead, cadmium, mercury, hexavelent chromium and specific bromine-based flame retardants
have not been used.
Applications
The applications of the component are used in relative humidity measurement, control and display. There
are many end products can be used. For example air conditioner, humidifier, dehumidifier, hygrometer,
recorder, transmitter etc
.
