TD1870 Multi-Function Calibrator

TD1870 Multi-Function Calibrator

The TD1870 Multifunction Calibrator is a wide-range, high-precision calibration instrument designed to meet the needs of modern metrology laboratories, industrial calibration units, and research facilities. It integrates ultra-precise DC/AC voltage and current sources, capable of delivering high-performance DC voltage, DC current, DC power, AC voltage, AC current, AC power, phase, and frequency outputs.

In addition to electrical signal outputs, the TD1870 offers resistance simulation, thermocouple simulation, RTD (thermal resistor) simulation, and pulse output, making it an ideal multifunctional tool for calibrating 5½-digit and lower digital multimeters and a wide range of precision electrical measuring instruments.
