Electrical Calibrators

Electrical calibrators are precision instruments used to generate, source, and measure electrical signals with a high degree of accuracy for verifying and adjusting measurement equipment. They produce stable, traceable outputs of voltage, current, frequency, and resistance, enabling calibration laboratories, quality assurance teams, and field technicians to maintain the accuracy of test instruments across industries.

These instruments are essential in national metrology institutes, accredited calibration labs, and industrial facilities where compliance with standards such as ISO/IEC 17025 is required. Electrical calibrators range from simple signal sources and voltage references to multifunction calibrators capable of simulating a wide range of electrical parameters.

Typical Applications

Calibrating digital multimeters, clamp meters, and panel meters in test laboratories
Verifying frequency references and oscillator standards in telecommunications and R&D
Sourcing precise voltage and current signals for process instrument calibration in industrial facilities
Standards maintenance and traceability verification in metrology and accredited labs
Capacitance and impedance standards calibration for LCR meters and impedance bridges
