HT-608 Compact Dew Point Sensor for Drying Processes, Dew Point Sensor down to -60 °C Td (-76 °F Td) Safeguard your system

Guard your equipment and production process

Maintaining the dew point of your air or gas system will prolong the lifetime of your equipment and reduce maintenance costs. For dew points related to production processes, guarding the dew point is critical for the end product and key in preventing costly production losses. Permanent monitoring enables you to detect and prevent problems quickly, and may provide visibility that a change in dew point is capacity or maintenance related.


HENGKO’ dew point sensors are designed for ease of use, incorporating all the features needed to make installation and operation as simple as possible. Our solutions cover all dew  point monitoring applications for industrial gases and compressed air dryers (refrigerant and desiccant).


Application examples:

> Monitoring compressed air quality of refrigerant and desiccant type air dryers

> Point-of-use dew point measurement

> Permanent measurement

> Guard critical processes e.g. in the semi-conductor, paint, pharmaceutical, food & beverage, and automotive industries

> Monitor demand air at machine/process level
