  • Humidity sensors
    Relative humidity, or RH, is the percentage of moisture in the air referenced to the maximum level of moisture the air can hold at that temperature and pressure. Relative humidity sensors come in both capacitive and resistive versions. Humidity changes the dielectric constant of the insulating...
  • Complying with ICH Guidelines Involving Temperature and Relative Humidity
    by insufficient air flow, heat or moisture loads within the space, or leakage to or from an adjacent space. § Sensor Accuracy - calibration uncertainty of both the temperature and relative humidity sensors. For example, consider a targeted condition of 25°C ±2°/60% RH ±5% where the recording...
  • Comparing Humidity Instrumentation
    by point comparison shows that there is no real advantage of instruments that use a chilled mirror over instruments that use a relative humidity sensor. Water Activity. Measuring Techniques. Commercially available water activity instruments commonly use one of the following humidity measurement techniques...
  • Adding Relative Humidity to Trace Concentration Gas Standards In a Permeation System (.pdf)
    Gas sensor sensitivity levels have increased in equipment where atmospheric conditions, such as relative humidity, directly affect test results. Calibrating for changes in relative humidity in trace level gas concentrations has generated the need for effectively adding relative humidity...
  • Measuring in High Humidity & Condensing Environments - Warmed Probe Technology (.pdf)
    Reliable, stable, and accurate humidity measurement in high relative humidity (>85%) and condensing environments has always been next to impossible without specialized technology. High RH and resulting water on the humidity sensor usually causes problems such as higher uncertainty, higher drift...
  • Application Note: Thermoset Polymer-based Capacitive Sensors - Measuring 100% RH (Relative Humidity) (.pdf)
    Thermoset polymer-based capacitive RH sensors directly detect changes in "relative saturation" as a change in sensor capacitance with fast response, high linearity, low hysteresis and excellent long term stability. Relative saturation is the same as ambient relative humidity when the sensor...
  • Comparing Two Measuring Techniques
    role. Measuring Techniques, Speed Most laboratories measure water activity with an instrument that either uses a relative humidity sensor or uses a chilled mirror. Instruments based on relative humidity sensors are typically less expensive than the chilled-mirror instruments. This raises the question...
  • Available Humidity, Dew Point, and Moisture Sensors, Probes & Connectors
    contain a glass substrate with a moisture sensitive polymer layer between two metal layers. By absorption of water, corresponding to the relative humidity, the dielectric constant and, as a result, the capacity of the thin-film capacitor are changing. The measuring signal is directly proportional...
