Additel’s multi-functional and loop process calibrators bring portability, accuracy, and compliance together in one rugged handheld package. Designed for technicians working in demanding industrial environments, these tools combine measurement, sourcing, simulation, and documentation across pressure, temperature, and electrical signals.

The ADT226 and ADT227 series provide advanced multi-functional calibration with large touchscreen displays, IP67 protection, dual-channel pressure modules, and optional ATEX/IECEx intrinsically safe models for hazardous sites. The ADT227 adds a full HART communicator, supporting smart transmitter calibration and troubleshooting. For high-risk environments such as oil & gas, hydrogen, or petrochemical plants, the ADT260Ex extends capability with multichannel reference recording, powerful data logging, and compatibility with external RTDs and pressure modules.

For routine loop testing and transmitter calibration, the ADT209/210 loop calibrators offer a lightweight, user-friendly solution with accuracy down to 0.01 % of reading.

Every calibrator is supplied with ISO 17025 accredited calibration data, backed by Additel’s reputation for reliability and Maximator Australia’s local service and support. From mining maintenance to hydrogen infrastructure, these calibrators ensure safe, efficient, and compliant field work.
