The E+E HTP501 humidity and temperature probe is a reliable, cost-effective probe for demanding applications such as drying processes. The IP66 rated stainless steel construction ensures durability. Besides RH and T, it calculates all humidity-related physical quantities like dew point temperature, absolute humidity, and mixing ratio.

The HTP501 employs a high-end E+E humidity sensing element with proprietary coating for exceptional long-term stability even in harsh operating environments. Measuring range: 0–100% RH, -40 to 120°C. Output: RS485 interface with Modbus RTU. Probe lengths: 200mm or 400mm. Filter options: metal grid (polycarbonate body), stainless steel sintered, or PTFE. Flexible high temperature cable with M12 connector. User configurable through free PCS10 software and optional Modbus configuration adapter.
