Ametek-Jofra Marine Temperature Calibrator MTC-140A (-17 to 140°C) or (-1 to 284°F)
The MTC series features a large back lit display that is easy to read even in well-lit areas. Units feature an informative display that provides icons and information regarding the status of the MTC and the calibration in-progress. The MTC series also features an auto-step function.
Using this function you may stay in the control room or on the bridge and monitor the temperature reading while the calibrator, located in the engine room by the sensor, automatically steps through a number of pre-programmed temperatures.
MTC Heats from -17 to 140°C (1 to 284°F) in just 18 minutes
The MTC series of portable temperature calibrators facilitates correct readings on all of your temperature monitoring devices. The MTC dry block design does not use any hazardous hot liquid and heats up and cools down much faster than traditional ways of calibrating temperature sensors on a vessel. You can reach from -17 to 140°C (1 to 284°F) in just 18 minutes and do it safely.
MTC-140 A Heating/Cooling Block
The model MTC-140 A features Peltier elements. In 1834, Jean Peltier, a French physicist found that an ’’opposite thermocouple effect’’ could be observed when an electric current was connected to a thermocouple. Heat would be absorbed at one of the junctions and discharged at the other junction. This effect is called the ’’PELTIER EFFECT’’. The practical Peltier element (electronic heating pump) consists of many elements of semiconductor material that are connected electrically in series and thermally in parallel. These thermoelectric elements and their electrical
interconnections are mounted between two ceramic plates. The plates serve to mechanically hold the overall structure together and to electrically insulate the individual elements from one another.
