High Insulation Testers

RCB-1 High voltage insulation testers verify and calibrate. The "RCB" is also used to verify and proof any high voltage insulation tester. It can be utilized to calibrate all high voltage insulation testers very accurately (analogs and digitals). The RCB-3 has less calibrated resistors than the RCB-1. RCB-3 is much smaller, lower in cost and as accurate as the RCB-1. (you need REC-1 on order to calibrate the H. V. insulation meters) The meters can measure accurately to 500 GW. RCB-3 is also a "state-of-the-art" high voltage resistor calibration box which can be used for demonstration and proofing in the field. The result is RCB-3, a portable set of H.V. resistors useable up to 10kV with a few combinations. For many, RCB-1 has to many functions if you just want to do a demonstration or verify the performance of the meter at some points only.
