The conversion of milli-volts to temperature is also done mathematically to take complete care of nonlinear characteristics of platinum thermocouples, leaving "no-room" for any false reading. With our thermocouple tip or minitips it takes about three seconds. This unique system while used with our different types of thermocouple tip provides you fast and accurate control on molten metal at every stage. The signal light indicates measuring sequence. Detection and indication of operational errors are shown on display immediately when observed. In addition to cutting the cost and maintenance free operation, it also gives comfort and safety to operator. Considering lifelong performance and lowest running cost.
