Temperature Calibrator
Overview
Product Overview
The APSL-C211 and APSL-C251 Temperature Calibrators are high-accuracy, high-resolution and high-reliability handheld calibrators integrating measurement and simulation of RTDs and thermocouples, as well as output and measurement of electrical signals including voltage, millivolt and resistance. Equipped with a high-brightness large backlit display, they feature easy operation, robust structure, compact lightweight design and cost-effective performance. Suitable for instrument workshops, metrology rooms and calibration laboratories, they serve as ideal calibration instruments for process control instruments.
