The company’s Protec P3000(XL) Helium Sniffer Leak Detector, the Sensistor Sentrac Hydrogen Leak Detector and the HLD6000 Refrigerant Leak Detector will be displayed at Booth 647 throughout the annual three-day show for manufacturing suppliers, buyers and users of assembly equipment at the Donald E. Stephens Convention Center.

“Year after year we discuss projects with more and more companies targeted to improve their leak detection processes,” said Thomas Parker, INFICON’s North American automotive market sales manager. “The automotive, medical and aerospace industries are all under pressure to manufacture and guarantee leak-free products.”

INFICON’s Protec P3000(XL)® Helium Sniffer Leak Detector is designed for demanding production environments for leak testing components in refrigerators, freezers, air conditioners, automotive air conditioners, engines, RAC components and other similar products.

The device provides quick results to make the best use of available cycle times and is both easy and comfortable to use. Protec P3000(XL) also can detect leaks from a considerable distance and provides the lowest detectable leak rate on the market.

A small display in the ergonomically-designed probe handle shows leak rates so that a technician can concentrate on the sniffing process while monitoring leak rates at the same time. A built-in illumination source on the probe helps insure precise positioning of the sniffer tip, and multiple alarm functions ensure that alarms cannot be overlooked.

The Protec P3000(XL) leak detector’s maintenance-free sensor uses innovative INFICON Wise Technology™. The Wise Technology sensor combined with a unique design and the ruggedness of the detector provides low cost of ownership and high up-time.

Manufacturers can cover a wide variety of test requirements with INFICON’s Sensistor Sentrac® Hydrogen Leak Detector. The sniffing device can handle manual and robot-assisted leak detection in environments with high levels of tracer gas, providing both selectivity and sensitivity.

Looking for leaks with diluted hydrogen tracer gas is an ideal solution for a variety of industrial applications. Sensistor Sentrac increases the advantages of the hydrogen gas method and was developed for improved operator-friendly use. A pressure-sensitive color touch screen provides a user interface with clear logical functions. It also makes settings simpler for various measuring situations and minimizes the risk of time-consuming errors. In addition, settings for a variety of measuring situations can be saved as configuration files and stored on an SD card for safe backup.

Sensistor Sentrac delivers leak-detection results immediately on both desktop and battery-operated models. The ergonomically designed probe handle delivers fast access to frequently used functions through a multi-function button. Probes can be used in rough environments that are wet or dusty. During leak testing, LED lights in the probe illuminate and precisely pinpoint leaks.

The new INFICON HLD6000 Refrigerant Leak Detector builds on the success of its predecessor, the HLD5000, with an updated hand probe that is more ergonomic, lighter, more flexible and more maneuverable. A new touch screen display also uses a more intuitive interface and provides easy-to-understand icons with fewer menu levels. Probes are available to detect leaks of R-1234yf, R-134a and CO2, as well as many other refrigerants.

As under-hood and interior space becomes increasingly tight, the HLD6000’s slim probe with twin LED illuminators makes it easy for operators to correctly place a probe in poorly lit areas to precisely locate leaks. Optional flexible probe tips also are available. Colored LED status lights alert the operator to device status, excess leakage detection and possible errors or warnings.

The HLD6000 has the same long-life highly sensitive infrared sensor as the INFICON HLD5000 Refrigerant Leak Detector and responds quickly to refrigerant leaks. Its dual inlet system compares background refrigerant to measured refrigerant at the sniffer tip to minimize false alarms and more efficiently pinpoint leaks.

The HLD6000 integrates into local networks with a variety of analog or digital interfaces through an optional I/O module. The USB interface provides data transmission to a connected flash drive, and its gas reservoir for a COOL-Check reference leak is stored in a “garage” beneath the main unit for quick replacement.

The Bubbleizer on display at the INFICON booth will compare four small to large leaks of 0.01, 0.1, 1.0 and 10 sccm (standard cubic centimeters per minute) side by side in four water-filled glass cylinders. Parker notes that in helium tests a crack of 15 microns wide by 1.5 mm long leaks at a rate of 0.003 sccm, but is undetectable in water-bubble testing.

INFICON is one of the world’s leading developers, producers and suppliers of instruments and devices for leak detection in air conditioning, refrigeration and automotive manufacturing. The company has manufacturing facilities in Europe, China and the United States, as well as sales and service offices throughout the world.
