DUAL MODE THERMOMETERS
REOTEMP’s Dual Mode Thermometer (DMT) is a convenient, multi-purpose indicator for local and remote temperature monitoring. This rugged dual-sensor system puts TWO independent sensors in ONE THERMOWELL, and allows easy tie-in to process controls. Both sensors are NIST traceable. Special sensor encapsulation and optional liquid filling make the DMT the most rugged, durable instrument of its kind.
- Allows independent local and remote reading (Up to 1000°F) from one thermowell
- Redundant sensors for simple, effective calibration or spot checking without removing instrument from thermowell
- Easily installed in any standard thermowell
- Interchangeable with existing thermometer, RTD, or Thermocouple

OPTIONS: Silicone case fill for vibration (3/8” stem only); 1 pt. or 3 pt. calibration, Hi-Vis™ Dial for bimet, sanitary Tri-Clamp® fittings, SS tag
NOTE: Thermowells should be used whenever the stem or bulb would be exposed to pressure, corrosion, velocity, abrasion or shear forces. Thermowells also make it possible to remove the thermometer without losing pressure or the contents of the process.
