Additel 227 Documenting Multifunction Process Calibrator with HART
The Additel 227 is a compact handheld documenting process calibrator that sources, simulates, and measures pressure, temperature, and electrical signals. The Additel 227 HART version (ADT227-HART) adds a built in full HART communicator so one tool handles the calibration, configuration, and troubleshooting of smart transmitters. A large smartphone style touchscreen and paperless documenting functions help technicians work faster and keep clean calibration records.
Key Features
- Built-in full HART communicator (ADT227-HART): works with most HART transmitters with an extensive device description (DD) library that is updated regularly
- Multifunction calibration: source, simulate, and measure pressure, temperature, and electrical signals in one device
- Large color touchscreen: a smartphone like interface that is easy to read and operate in the field
- Documenting calibration tasks: a built in task application for automated paperless calibration management
- ACal software integration: results can be exported to Additel calibration management software
- Data logging: record pressure, temperature, and electrical readings over long periods and store up to 500 results
- Dual pressure module ports: connect pressure modules for flexible range coverage including high static differential pressure measurement down to 0.002% FS
- Electrical performance: for example DC voltage sourcing to 15 V with 0.1 mV resolution on the standard model
- True RMS voltage measurement: with high voltage capability to ±300 V AC (non Ex model)
- Built-in barometer: for gauge and absolute pressure work
- Connectivity: USB Type C plus Bluetooth for connecting mobile devices at up to about 20 m
- IP67 rated: protection against dust and water in the field
- Intrinsically safe option (227Ex): ATEX, IECEx, CSA, and UKCA certified for hazardous areas
- ISO 17025-accredited calibration with data supplied with the unit
- Standard accessories: test leads right angle test leads (non Ex) pressure module cable USB cable (non Ex) and a hanging strap with magnet
Typical Applications
- Calibrating and verifying HART smart transmitters
- Process instrumentation maintenance in refineries, chemical, and power plants
- Pressure transmitter, gauge, and switch calibration
- Temperature instrument calibration with RTD and thermocouple signals
- Loop checks and troubleshooting
- Hazardous area work with the Ex model
Why Choose It
The Additel 227 combines a HART communicator multifunction calibrator, and documenting tool in one pocket sized rugged unit. That replaces several separate devices reduces paperwork errors and helps technicians complete calibrations faster and with traceable results.
