About INFICON

INFICON is a manufacturer of instrumentation and sensors for vacuum measurement, leak detection, and gas analysis. The company was founded in 1969 as a spin-off from Balzers, a Liechtenstein-based vacuum technology firm, and has since established itself as a supplier of precision instruments for industrial and scientific applications. INFICON's product portfolio includes vacuum gauges, residual gas analyzers, mass spectrometers, leak detectors, and refrigerant management tools. These products are used in semiconductor fabrication, vacuum coating, refrigeration and air conditioning service, automotive manufacturing, and general industrial processing. The company operates globally, with manufacturing and support facilities in Europe, Asia, and North America.

3G Electric supplies a range of INFICON products focused on HVAC/R service, leak detection, and vacuum measurement. The line includes wireless electronic refrigerant scales, infrared sensor refrigerant leak detectors, digital vacuum gauges, combustible gas detectors, A2L-compatible refrigerant recovery machines, and replacement filters and sensors for leak detectors. These products are used by technicians and engineers for charging, recovery, leak checking, and vacuum verification in refrigeration systems. Key technical attributes include measurement ranges from 1 micron Hg to 760,000 micron Hg for vacuum gauges, leak detection sensitivities down to 0.03 oz/yr, and compatibility with A2L refrigerants such as R-1234yf and R-32. Many units carry CE and UKCA listings, and some models offer IP-rated enclosures for field use.

INFICON instruments are designed for field and workshop environments. The Pilot Plus digital vacuum gauge, for example, provides visual indication via an LCD display and operates on a 9V battery, with connection options including 1/4 in male SAE flare and 16 mm male flange. The D-TEK series leak detectors use infrared sensors to detect refrigerant leaks, with models offering 0.04 oz/yr or 0.03 oz/yr sensitivity and A2L compatibility. The Vortex refrigerant recovery machine features a 1 hp AC motor with vapor recovery rates of 0.5 lb/min and liquid recovery rates of 5.1 lb/min, and includes a shoulder strap for portability. The wireless electronic refrigerant scale has a 275 lb capacity and ±0.06% accuracy, with a wired handset display and carrying case. Replacement sensors, such as the 724-701-G1, are available to maintain leak detector performance.

3G Electric supports the INFICON line by stocking these products for global distribution. We provide technical specifications, manufacturer part numbers, and compatibility information to help procurement and maintenance teams select the correct instrument for their application. Our catalog includes both current and legacy INFICON models, and we can source additional items from the manufacturer's catalog on request. For buyers needing assistance with cross-referencing or identifying the right replacement sensor or gauge, our team can provide support based on the published specifications and model numbers.

Frequently asked questions

Common questions about INFICON from 3G Electric.

What is the measurement range of the INFICON Pilot Plus digital vacuum gauge?

The INFICON Pilot Plus digital vacuum gauge measures from 1 micron Hg to 760,000 micron Hg. It provides visual indication via an LCD display and operates on a 9V battery. Two connection types are available: a 1/4 in male SAE flare right-hand and a 16 mm male flange. The gauge is used to monitor vacuum levels during evacuation of refrigeration systems. It is available in A2L-compatible versions for use with mildly flammable refrigerants. The Pilot Plus series is part of INFICON's line of vacuum measurement instruments for HVAC/R service and industrial vacuum applications.

What is the sensitivity of INFICON D-TEK refrigerant leak detectors?

INFICON D-TEK refrigerant leak detectors are available with infrared sensors offering sensitivities of 0.04 oz/yr or 0.03 oz/yr, depending on the model. These detectors are A2L compatible, meaning they can be used with mildly flammable refrigerants such as R-1234yf and R-32. They also support common refrigerants like R-134a and R-22. The D-TEK 3 model includes an IR sensor, sensor filter, AC adapter, and carrying case. The handheld design allows for field use in HVAC and automotive refrigerant leak detection. Replacement sensors are available to maintain sensitivity over time.

What are the recovery rates of the INFICON Vortex refrigerant recovery machine?

The INFICON Vortex refrigerant recovery machine has a 1 hp AC motor and achieves vapor recovery rates of 0.5 lb/min and liquid recovery rates of 5.1 lb/min. It is A2L compatible, allowing recovery of mildly flammable refrigerants. The unit weighs 29.8 lb and includes a shoulder strap for portability. It is designed for use in HVAC/R service and automotive applications where refrigerant must be removed from systems before repair or disposal. The Vortex is part of INFICON's refrigerant management product line, which also includes charging scales and vacuum gauges.

What is the capacity and accuracy of the INFICON wireless electronic refrigerant scale?

The INFICON wireless electronic refrigerant scale has a maximum capacity of 275 lb and an accuracy of ±0.06% (±3 g). It features a wired handset display and a resolution of 0.1 oz. The scale is designed for use with R-134a refrigerant and includes a carrying case, magnetic handpiece, and strap. It is CE and UKCA listed. This scale is used for precise charging of refrigerant into HVAC/R systems, where accurate weight measurement is critical for system performance. The wireless design allows the technician to operate the handset away from the scale platform.

What replacement sensors are available for INFICON leak detectors?

INFICON offers replacement sensors for its leak detectors, such as the 724-701-G1. This sensor is compatible with R-1234yf refrigerant and is A2L compatible. It is designed for use with model 721-202-G1 and provides 0.03 oz/yr sensitivity. Replacement sensors restore leak detection capability when the original sensor reaches the end of its life or becomes contaminated. They are part of INFICON's aftermarket support for its D-TEK and other leak detector series. 3G Electric stocks this sensor and can advise on compatibility with specific detector models.

Is the INFICON combustible gas detector suitable for detecting gasoline vapors?

Yes, the INFICON combustible gas detector (MPN 718-202-G1) is designed to detect gasoline vapors and other combustible gases. It has a detection range starting at 1 ppm for gasoline and provides a sound alert when gas is present. The unit includes a hard carrying case. This detector is used in applications such as fuel storage, automotive repair, and industrial settings where combustible gas leaks pose a risk. It is a portable, handheld instrument. For specific gas response factors and calibration information, refer to the manufacturer's documentation.
