Compact Moisture and Temperature Transmitter for Oil

The MMT310 series incorporates the latest generation of the Vaisala HUMICAP® Sensor, developed for
demanding moisture measurement in liquid hydrocarbons. The sensor’s excellent chemical tolerance provides accurate and reliable measurement
over the wide measurement range.

The MMT310 series can be used in lubrication and hydraulic systems as well as in transformers. It can be used for on-line moisture monitoring and as a control function, allowing separators and oil purifiers to be started only when necessary.
