JH-2000 Handheld intelligent signal calibrator is an intelligent industrial instrument calibrator, high precision, small size, can be used to adjust the field of industrial instrumentation can also be used for calibration of laboratory instrumentation. JH-2000 handheld powerful signal calibrator can simulate a variety of industrial control process output and control signals required, and hand-held signal calibrator can measure these industrial control signals generated in the process. JH-2000 hand-held signal calibrator powerful and comprehensive output allows you to live comfortably in the tight construction to carry out a variety of instrument calibration and commissioning process. And in the two-wire instrument set-ups, JH-2000 hand-held signal calibrator demonstrated its superiority, it provides you with DC24V power supply circuit, a direct-wire instrument for the transfer test. In the measurement 20mA, JH-2000 hand-held signal calibrator can be a stable display 20.000 (5 digits) value. Because JH-2000 hand-held multi-function signal calibrator with more features, performance characteristics, it is the process of debugging and testing of industrial controls an essential tool. All features are designed to be very easy to use. The JH-2000 hand-held calibrator signal structure is specialized for field use, designed to operate with one hand, adjust the settings of all instruments with one hand only.
