Each high voltage thermal converter is manufactured in a copper alloy high polished chrome plated housing tube for highest surface reflection and adjusted for the best AC-DC difference and so that a constant impedance is held through the entire frequency range. Each unit can be supplied with BNC, N, or GR874 input connectors.
The high voltage thermal converters are manufactured with vacuum thermocouples with a maximum DC reversal error of 0.02%. In addition, a DC reversal error of 0.005% is available upon request.
Measure Tech uses a fully automated calibration system, EL-2400, which was manufactured for Air Force precision measurements laboratories. The calibration is performed by comparing our product to a calibrated standard traceable to NIST.
In addition, for all thermal converters a 4' long low noise cable (model number EL-2000) is available with excellent shielding capabilities. This product mates with all of Measure Tech's thermal converters as well as any other thermal converter with an output connector of MS3102A-10SL-3P.
