The Additel 226 multifunction process calibrator combines portability, functionality, and accuracy into a powerful and cost-effective process calibrator. An ATEX certified intrinsically safe option allows you to perform calibration work in the harshest of environments.

The 226 has been designed with ruggedness and dependability in mind and meets IP67 standards with a 1-meter drop test, 4G vibration, xenon exposure, and 130g steel ball drop testing of the display. The unique internal circuit design ensures confidence in critical calibration and measurement.

The onboard applications provide useful features including high-static differential pressure mode (0.002% FS), pressure leak test, safety valve test (10 readings/second during valve crack), analog transmitter calibration, unit converter, thermal calculator, and snapshots.

The 226 Ex intrinsically safe model has ATEX, IECEX, CSA and UKCA certification (Ex ia IIC T4 Ga) for use in potentially explosive environments such as oil and gas platforms, refineries, chemical and petrochemical plants. The non-Ex version includes True RMS measuring function. Bluetooth connectivity up to 20 meters and USB Type-C with 35-hour battery life provide flexible operation.
