E+E HTS401 - Industrial Humidity Transmitter (High‑Temp Applications)

The HTS401 delivers modern humidity and temperature measurement that is fail-safe, precise and ready for the most demanding environments. With measurement accuracy up to ±0.95 % RH and ±0.1 °C (0.18 °F) and an operating range from −40 °C to +80 °C (−40 to +176 °F) , the HTS401 integrates flexibly into diverse applications, from outdoor installations to cleanroom environments.

• The rapidX measuring module can be replaced within seconds without tools.
• Precise process control and tangible energy savings in operation
• Calibration is straightforward and automatically provides a digital 3.1 inspection certificate, making the HTS401 ideal for validated or documentation-critical processes.

Industrial processes place stringent demands on instrumentation. Extreme ambient conditions, aggressive media, chemically intensive cleaning and the need for accurate, fail-safe data are common. Conventional sensors soon reach their limits because of condensation, corrosion, temperature extremes or labour-intensive maintenance. This is where the HTS401 excels.

With a robust and intelligent protection concept that combines the E+E sensor coating with connection encapsulation, the HTS401 remains ready for service even under severe stress. The Automatic Recovery function (ARC) protects the sensing elements against adverse chemical influences. In the event of condensation risk, the Condensation Guard (CG) intervenes before measurement performance is affected.

Typical Applications

• High-end HVAC: data centers, swimming halls, outdoor applications
• Agriculture: greenhouses, stables, storage and ripening
• Pharmaceutical Industry: cleanroom monitoring
