Analog, Square Panel Mount of RdUffi'P'dfta$ie

Richards Analog Panel Mount Meters are available for both Type K and Type J thermocouples. lt is important to note that the Ml0-K, M1O-J, and the Ml1-J meters have a external resistance of 10 Ohms. ln order to maintain the accuracy of the readings, the total resistance of the thermocouple and extension wires combined must be equal to 10 Ohms. The Ml unit has 1 Ohm external resistance. This requires the total resistance of the thermocouple and extension wires combined to be equal to 1 Ohm. The Ml meter is normally used in our portable molten metal handle assembly, but they may be used in situations where long extension wires are not required. The M10 and M11 type instruments are usually used in situations where longer extension wires are needed. t N96: Resistance values for thermocouple and extension wire can be found in the engineering section of this catalog.
