The employed high-end E+E RH and T sensing element is heated autonomously and enables reliable and
long-term stable measurements in extremely humid or chemically polluted environments. The monolithic

contamination. In addition, it is perfectly protected by the E+E proprietary coating.
Different heating modes of the monolithic RH and T sensing element allow for best adaption to the specific
needs of each measuring task. Furthermore, types T7, T17 and T28 offer a dual heating system (probe body
and sensing element are heated) to prevent condensation on the RH sensing element and on the probe body for
continuous high humidity operation.
The measured data is available on two freely scalable analogue outputs, on the RS485 (Modbus RTU) or
Ethernet-PoE (Modbus TCP) interface and on the alarm (relay) outputs. The configuration and the RH and T
adjustment of the HTS801 can be performed with the free PCS10 Product Configuration Software. An optional
3.5” colour display with push-buttons is available for configuration and visualisation.
The HTS801 with PC7 option (see ordering guide) features the intelligent pluggable rapidX probe, which enables
a plug-and-play probe exchange.
The optional Automatic ReCovery (ARC) module allows for external triggering of the heating functionality.
