As the only manufacturer of a single junction vacuum thermocouple in the world, MeasureTech’s product is designed and manufactured as a device for calibrating high frequency current and voltages which is used for the highest measurement accuracies and used to validate instruments in national and calibration laboratories.
MeasureTech developed a process that allows for the thermocouples to be manufactured with cold beads and evanohm wires along with platinum leads. This innovative design produces extremely low AC-DC differences and DC reversal errors.

The following AC-DC difference data is from a customer at the National Research Council Canada.
