Constructed for humidity measurement in industrial drying applications with particularly high temperatures. As the probes are designed to be positioned directly in hot processes, there is no need for sampling systems and trace heating. Optional data logging and (W)LAN interface.

• The DMT345 measures humidity in temperatures up to 180°C (+356 °F)
• The DMT346 measures humidity in temperatures up to 350 °C (+662 °F)
• Unique auto-calibration
• Vaisala DRYCAP® Sensor provides accurate, reliable measurement with excellent long-term stability and fast response
• Withstands condensation
• Optional local display with keypad, mains power supply module and alarm relays
• User-programmable, versatile and easy to use
• Integrated data logging, with over four years of measured history
• LAN and WLAN communication options
