473-SHX dew point mirror – Process Insights

Send me more information about this product

Humidity and temperature reference hygrometer for temperature up to 125 °C.

The SHX measuring head is an evolution of the tried and tested SH measuring head. It is able to operate in test conditions up to 125 °C thanks to the use of optical components, electronics and materials that are able to withstand high temperatures.

The key components of the SHX such as the optical module and fan assembly can be easily replaced by the user without the need for system re-calibration.
