INFICON

INFICON is a global manufacturer of instrumentation and sensor technologies for the refrigeration, HVAC, and industrial gas detection markets. Headquartered in Syracuse, New York, the company has a history dating back to the 1960s, with a focus on developing precision leak detection, vacuum measurement, and gas analysis equipment. Their product portfolio includes refrigerant leak detectors, vacuum gauges, charging scales, combustible gas detectors, and reference leaks, all designed for use in field service, maintenance, and manufacturing environments. INFICON devices are built to meet rigorous industry standards, with many models offering A2L refrigerant compatibility, sensitivity ratings as low as 0.2 oz/yr, and measurement ranges from 1 micron Hg to 760,000 micron Hg. The company's heated diode and ultrasonic sensor technologies provide reliable detection across a variety of refrigerants, including R-600A, R-448A, and R-436B. INFICON also produces digital vacuum gauges with LCD displays and wireless electronic scales with ±0.06% accuracy, supporting precise charging and evacuation procedures. Their reference leaks, calibrated to 0.18 oz/yr, are used for verifying detector performance. 3G Electric stocks over 20 INFICON SKUs, including replacement sensors, filters, and accessories, with datasheets and logistics support for global procurement. These products are applicable in commercial refrigeration, HVAC system installation, industrial gas monitoring, and automotive AC service, where accurate leak detection and vacuum measurement are critical for system integrity and regulatory compliance.

Frequently asked questions

Common questions about INFICON from 3G Electric.

What types of refrigerants are INFICON leak detectors compatible with?

INFICON leak detectors are compatible with a wide range of refrigerants, including R-600A, R-448A, R-436B, and R-134A. Many models, such as the heated diode sensor (MPN 705-202-G1) and ultrasonic sensor (MPN 711-202-G1), are A2L compatible, meaning they can detect mildly flammable refrigerants. The specific compatible refrigerant type is listed for each model, so you should verify compatibility with your target gas before selection.

What is the sensitivity range of INFICON replacement sensors?

INFICON replacement sensors, like the MPN 724-701-G3, offer a sensitivity of 0.2 oz/yr. This level of detection is suitable for locating small refrigerant leaks in HVAC and refrigeration systems. The sensitivity is factory-calibrated and designed to maintain accuracy over the sensor's service life, though periodic verification with a reference leak is recommended.

How does the INFICON Pilot Plus vacuum gauge measure pressure?

The INFICON Pilot Plus vacuum gauge (MPN 710-202-G1) uses a visual indication method to measure pressure from 1 micron Hg to 760,000 micron Hg. It features an LCD display and a 1/4 in male SAE flare right-hand connection. The gauge operates on a 9V battery and provides real-time readings for evacuation and vacuum testing in HVAC applications.

What is the accuracy of INFICON charging scales?

INFICON charging scales, such as the MPN 501-202-G1, have an accuracy of ±0.06%. This high precision ensures accurate refrigerant charging, which is critical for system performance and efficiency. The scale has a 275 lb maximum capacity and includes a wired handset display and carrying case for portability.

Are INFICON combustible gas detectors suitable for detecting gasoline vapors?

Yes, the INFICON combustible gas detector (MPN 718-202-G1) can detect gasoline vapors at concentrations up to 1,000 ppm, with a minimum detection limit of 1 ppm. It uses a sound alert to indicate gas presence and comes with a hard carrying case. This detector is designed for industrial and field use where combustible gas monitoring is required.

What is the purpose of INFICON reference leaks?

INFICON reference leaks, such as the MPN 703-080-G29 (R-600A) and MPN 703-080-G10 (R-134A), are calibrated devices that release a fixed leak rate of 0.18 oz/yr. They are used to verify the sensitivity and performance of refrigerant leak detectors, ensuring that the detector is functioning correctly before and during service work.
