The VTH531-A Series integrates an ultra-high-temperature-resistant sensing element with a durable 316L stainless steel probe, delivering precise measurements in extreme environments up to 190°C. Engineered for accuracy, wide temperature adaptability, long-term stability, and extended service life, this sensor excels in demanding industrial applications.

Even in high-temperature environments (80–185°C), the VTH531-A Series maintains reliable humidity measurement performance, making it ideal for monitoring moisture levels in:

Industrial kilns & furnaces

High-temperature ovens

Coking gas pipelines

Other harsh-process gas streams

Designed for resilience and precision, it ensures consistent performance where standard sensors fail.
