Richards Analog Panel Meters are available for both Type K and Type J thermocouples. It is important to note that the M10-K , M10-J , and the M11-J , have an external resistance requirement of 10 Ohms. In order to main- tain the accuracy of the readings, the total resistance of the thermocouple and the extension wires combined must be equal to 10 Ohms. The M1 unit has an 1 Ohm external resistance requirement. This requires that the total re- sistance of the thermocouple and the extension wires combined must be equal to 1 Ohm. The M1 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. ! Note: Resistance values for thermocouple and extension wires can be found in the engineering section of this catalog.
