EKO-9301 Portable comprehensive calibratorDetailed product description：

The EKO-9301 portable comprehensive calibrator has signal output and testing functions. When powered by the internal battery, there is one current (or voltage) output, and when powered by 220V AC, there are two current (or voltage) outputs. It also has a 24V DC working power supply for two-wire transmitters. This instrument can measure DC voltage signals from 0-220mV.DC, 0-6V.DC, and DC current signals from 0-30mA.DC. The instrument also has additional functions to simulate some commonly used resistance values of PT100 or Cu50 thermal resistors. This instrument has high accuracy and reliability, compact structure, and easy use, making it particularly suitable for on-site inspection of various industrial automation instruments and devices, such as DDZ-II, III, and I series electric unit combination instruments, various recording instruments, XCZ, XCT series electric coil instruments, XMZ, XMT series digital thermometers.
