Additel 226 Multifunction Process Calibrator ATEX Certified Intrinsically Safe NVLAP ISO 17025 accredited calibration certificate with data

The Additel 226 multifunction process calibrator combines portability, functionality, and accuracy and packages it into a powerful and cost effective process calibrator, which has an ATEX certified intrinsically safe option allowing 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. Other environmental conditions have also been considered, such as temperature and humidity. To combat these external elements, Additel has designed a unique internal circuit design and process technology to allow for the utmost confidence in critical calibration and measurement.

The 226 provides improved accuracies including an electrical accuracy of 0.005% RD + 0.005% FS, high-static differential pressure mode accuracy to 0.002% FS and across the board improvements in temperature measurement accuracies.

The onboard applications provide a useful selection of features including high static differential pressure mode, pressure leak test, safety valve test, analog transmitter calibration, unit converter, thermal calculator, and snapshots. High static differential pressure mode uses two sensors and unique calculation technology to achieve a differential pressure measurement to 0.002% FS. The leak test will automatically calculate the pressure drop to determine a leak condition. The safety valve test is a specialized task which captures the exact pressure release point by taking 10 readings per second during a valve crack test. 

The 226 Ex intrinsically safe model has passed the most stringent testing by certified organizations to acquire intrinsically safe certificates, ATEX, IECEX, CSA and UKCA. The explosion-proof grade (Ex ia IIC T4 Ga), can be widely used in potentially explosive environments, such as oil and gas platforms, oil refineries, chemical and petrochemical plants, pharmaceutical industries, energy and gas processing industries. Each intrinsically safe calibrator has an advance transflective color LCD display which has enhanced visibility when viewed in direct sunlight.

The 226 non-Ex version is equipped with a true effective value RMS measuring function, which can measure the RMS of various waveforms with no need to consider distortion or waveform parameters and other errors caused by various waveforms.

Users can remotely connect mobile devices to the 226 via a Bluetooth connection at an unobstructed distance of up 20 meters. The included USB type-C comm port and cable provide a hard wired communication option as well as charging for the removeable and replaceable Li-ion battery, which provides up to 35 hours of run time.
