TH0540 Precision Current Transducer
The TH0540 Series is a high-precision I/I type AC/DC current transducer designed for reliable and accurate measurement of electrical signals across a wide current range. These precision transducers are specifically developed as companion accessories for instruments such as TD1300, TD1310, TH1300, TH0560, TK6500 and other compatible systems to enable accurate AC/DC current measurement in laboratory and calibration environments.
The TH0540 transducers deliver high stability, low phase deviation, wide bandwidth, and excellent long-term consistency, making them suitable for metrology laboratories, industrial testing equipment, calibration systems, and automated measurement environments.
