LFH30 sensitive components use a polymer film humidity sensitive capacitor and PT1000 temperature sensitive resistors.
The breathable coating and SMD injection molding process can ensure the long stability of the probe in high humidity and
condensation environments. It is calibrated with advanced humidity and temperature measurement technology to ensure
accuracy. It is suitable for high-standard building incubators, industrial dehumidifiers, and other fields.
