The Additel ADT209 and ADT210 loop calibrators are lightweight, rugged tools designed to simplify loop testing, transmitter calibration, and troubleshooting in the field. Engineered for portability and ease of use, they combine high accuracy, intuitive controls, and long battery life to deliver maximum productivity for technicians in industrial and process environments.

The ADT209 offers accuracy of 0.03% of reading, while the ADT210 provides industry-leading 0.01% of reading for demanding calibration work. Both models allow measurement, sourcing, and simulation of current (mA), voltage, and switches. Features include simultaneous mA and % span display, step and ramp functions, and built-in HART 250Ω resistance for transmitter calibration.

Compact and rugged, each unit is drop-tested, vibration-resistant, and equipped with a large, easy-to-read display. Powered by a standard 9V battery, they provide up to 50 hours of measurement mode runtime, ensuring reliability during extended field use.

Every calibrator is supplied with an ISO 17025-accredited calibration certificate, giving technicians confidence in compliance and audit readiness. Backed by Maximator Australia’s local support, the ADT209 and ADT210 are ideal for maintenance teams in mining, oil & gas, hydrogen, and industrial plants.
