Moisture and Temperature Transmitter for Oil
  Overview
  • Three probes for moisture in oil measurements (MMT332 for high pressure installation, MMT337 with optional Swagelok connector, is ideal for tight spaces with a thread connection, and MMT338 for pipeline installations)
  • Continuous on-line measurement of moisture in oil
  • Ball valve installation - no need to shut down the process
  • Incorporates Vaisala HUMICAP® Sensor - excellent long-term stability
  • Integrated data logging, with over four years of measured history
  • LAN and WLAN communication options
  • Successor of the HMP228 Moisture and Temperature Transmitter for Oil
