    Resistive hygroMeter

    Overview Products Knowledge Terms
    Resistive hygrometers measure humidity by utilizing the characteristic of moisture-sensitive materials changing their resistance upon absorbing moisture. Their core component is a substrate coated with conductive polymers or salts. When environmental humidity changes, the ionization degree of the material alters, leading to a corresponding relationship between resistance and humidity. This instrument is used for humidity monitoring in settings such as warehouses and greenhouses, and in paper mills, it can monitor the moisture content of paper.
    Selection
    When selecting, pay attention to the sensor type: polymer sensors are suitable for normal temperature and humidity, while ceramic sensors are resistant to high temperatures. Choose the measurement range as needed, such as 0-40%RH or 0-100%RH. Common accuracy ranges from ±2% to ±5%RH. Note the temperature compensation function and ensure the operating temperature range matches the environment. For long-term use, select sensors with anti-condensation structures, and opt for corrosion-resistant housings in corrosive environments. Calibrate regularly using standard salt solutions.

    Selection of Temperature and Humidity Meters: Sensor Accuracy and Response Time
    When selecting a temperature and humidity meter, sensor accuracy and response time are key parameters. Accuracy refers to how close the measured value is to the actual value, typically expressed as an allowable error, with high-precision sensors being more costly.
