Horizontal installations need a probe format that fits cleanly into the measuring point and keeps the instrument easy to access. S.TO1 is the horizontal probe option for compatible HD2717T and HD2817T transmitters, indicators and ON/OFF regulators, supporting temperature and humidity monitoring in industrial and HVAC applications.
The probe measures temperature and relative humidity and enables the connected instrument to calculate dew point, wet bulb temperature, absolute humidity and mixing ratio. Factory calibration and internal calibration data storage support dependable replacement and continued measurement quality during service.
Its 135 mm AISI 304 stem and P7 filter give the S.TO1 a clearly defined mechanical format for horizontal probe configurations. As an interchangeable probe, it can be replaced on-site without interrupting the process.
