TH2518 Series DC Resistance/ Temperature Meter

Tonghui TH2518 series resistance/temperature scanner adopts the design concept of synchronous plug-in card, which can support up to 6 plug-in board test units, and realize synchronous measurement between plug-in boards, which greatly improves the scanning measurement speed. Each measurement board contains 16 test terminals, and the combination of test terminals can be freely programmed by the user, and up to 90 resistance/temperature scan measurement channels can be configured. The sorting comparison boundary and outputting comparison sorting signal can be independently designed for each channel measurement.
