Barfield (AFI KLM E&M)
Welcome to the Barfield brand page. Renowned as a premier manufacturer of Ground Support Test Equipment (GSTE), Barfield is a highly respected authority in aerospace maintenance, delivering industry-standard avionics testing instruments and specialized repair solutions for commercial, regional, and military aviation worldwide.
The Benchmark for Air Data & Pitot-Static Testing
For decades, Barfield has set the operational benchmark for air data instrument calibration. Avionics maintenance repair organizations (MROs) and airline technicians rely heavily on Barfield test sets to execute critical flight-safety verifications. Their hardware stands out for combining high-accuracy pressure control systems with rugged, hangar-proof engineering.
Barfield’s elite product segments include:
-
Automated RVSM Pitot-Static Testers: The industry-leading DPS1000 and DPS500NG / DPS501NG series, which provide fully automated simulation and precise calibration of cockpit Altimeters, Airspeed Indicators, and Air Data Computers (ADCs) within strict RVSM guidelines.
-
Digital & Analog Flightline Kits: Time-tested workhorses like the Barfield 1811 Series (including the digital 1811NG), designed for fast, dependable pitot-static leak checks directly on-aircraft.
-
Fuel Quantity & Turbine Systems: Advanced diagnostic tools such as the DFQ40K (Digital Fuel Quantity Tester) and the TT1000A / TT1200A turbine temperature test sets, ensuring precision monitoring of engine and fuel tank capacitance arrays.
Streamlined Fleet Maintenance & Safety Automation
Barfield instruments are engineered to simplify complex testing workflows. By incorporating automated safety features like smart “Go-To-Ground” depressurization routines and programmable aircraft memory limits, Barfield equipment actively safeguards fragile cockpit instrumentation against catastrophic over-pressure damage. This absolute reliability helps maintenance teams minimize aircraft-on-ground (AOG) time safely.
