With its small dimension and high sensitivity, the IST AG K5-W capacitive RH humidity sensor was developed for applications where an accurate measurement in low humidity ranges is required. The sensor is characterized by the outstanding stability in low humidity, very low drift and a high chemical resistance. With its excellent sensor characteristics, the K5-W is the optimal choice for low humidity environments. The humidity sensor is capable of measuring 0 % RH to 100 % RH (maximal dew point +85 °C) with a capacitance of 200 pF ±50 pF (at 30 % RH and +23 °C) and operates within a temperature range of -40 °C to +150 °C.The IST AG K5-W humidity sensor is available with CuP-SIL wire post-plated with Sn as standard configuration.

The IST AG P14 2FW Thermo was designed especially for dew point applications and humidity generators. The favorable one-chip solution consists of a capacitive humidity sensor, based on the standard P14 sensor, together with a heating element, which, at the same time, works as a valid Pt100 sensor. The sensor achieves outstanding measurement accuracy due to the optimal thermal coupling which enables a fast recovery time. Due to heating from the Pt100, humidity is quickly released and enables fast re-measurements after condensation. Furthermore, the Pt100 sensor heats out gases or vapors from the polymer, which might cause a drift of the humidity signal. The P14 2FW Thermo humidity sensor is capable of measuring 0 % RH to 100 % RH (maximal dew point +85 °C) with a capacitance of 150 pF ±50 pF (at 30 % RH and +23 °C) and operates within a temperature range of -50 °C to +150 °C.The IST AG P14 2FW Thermo humidity sensor is available with Ni/Au-flat wire as standard configuration.
