Electrical Calibration

Process Calibrator Specialists

Electrifying Electrical Capability

APL has moved on from being only a pressure specialist laboratory. Many process instruments today offer multiple functions on a single device. Our electrical capability is finely tailored for calibrating multifunction and process calibrators as well as a range of standard electrical meters, calibrators and decade resistors, including accredited calibration of temperature functions by electrical simulation (thermocoule and RTD scales).
