  • Interchangeable probes
  • Great accuracy and long term stability
  • Easy loop calibration
  • Wide temperature working range


The Setra SRH400 is an innovative and modular humidity (RH) and temperature (T) transmitter designed to meet the diverse needs of various applications. The SRH400 system consists of a versatile basic unit and interchangeable probes, providing flexibility and ease of installation.

The basic unit of the SRH400 can accommodate either one combined S07 RH and T probe or two separate S07 probes for RH and T measurements. The probes are available in plastic or stainless steel enclosures and can be directly plugged into the basic unit or connected using M12 extension cables up to 10 meters long. For duct installations, an optional kit is available to mount the probes securely. The SRH400 basic unit is designed with a metal enclosure suitable for wall mounting.

The SRH400 provides accurate measurements of humidity and temperature, with the values available through two analog voltage or current outputs (2-wire, 4-20 mA). Additionally, an optional display is available to view the measured values. The transmitter allows for easy calibration adjustments for RH and T with push buttons located on the electronics board of the SRH400 unit. Alternatively, the SRH400 probes can be individually adjusted using the PCA Product Configuration Adapter (refer to the S07 datasheet for more details).

To ensure durability and reliability in aggressive environments, the SRH400 is fully shielded and features a powder-coated finish with a robust die-cast construction. All external hardware components are made of stainless steel, offering excellent resistance to corrosion.
