Pressure Decay, Vacuum Decay, Mass Flow Lid Deflection, Force Decay, Headspace Gas Analysis
Leaks, even when they are small, can have a significant impact on the performance of a part or component or cause equipment to fail. Cracks and faulty seals are often the cause of these leaks, but they can often be detected by conducting vacuum testing on components prior to manufacturing.
Vacuum leak testing is the principal leak test method for testing sealed parts that could have leakage from an external source into their housings and casings. Prime candidates for vacuum leak test procedures include:
- Underwater sensors or housings
- Outdoor electrical housings
- Sealed components
- Components associated with vacuum sources
Pressure Decay Test Systems
Pressure decay leak testing is the most commonly used today. Its simplicity makes it easy to automate and to integrate into production/assembly processes.
In simplest terms, the pressure decay test fills a pressure vessel with air until it reaches its target pressure, cuts the air source to isolate the pressure, and measures the decay (loss) of that pressure over a set period of time; any loss in pressure indicates a leak. The sensitivity of the pressure decay method is a function of the test part’s size and the test time. Most tests can be performed rather quickly, with highly accurate results, but the larger the part, the longer the cycle time that is required to achieve an accurate test result.
Benefits of Pressure Decay Leak Testing
- Sensitive enough to detect very small leaks
- Can test in pressure or vacuum environments
- Determines a leak rate based on pressure or vacuum
- Can calibrate to a volumetric flow
- Can report pressure or flow loss (psig or scc/min)
- Provides a simple and highly effective leak test method

NEW – XL3000flex Helium and Hydrogen Sniffer Leak Detector
HIGH FLOW Technology for Highest Measurement Certainty and Fastest Throughput
XL3000flex sniffer leak detector is the first device to detect leaks with forming gas (95% nitrogen and 5% hydrogen) as accurately as with helium, with a smallest detectable leak rate of 1 ∙ 10-7 mbar∙l/s for both test gases.
The XL3000flex provides the best flexibility to choose the test gas which is easiest to obtain according to lower cost. In addition, the XL3000flex uses the INFICON High Flow Technology: the device operates with a gas flow of 3000 sccm – the highest gas flow available on the market today. This allows the sniffer tip to be moved over the test piece at some distance and at a higher speed, so even the most inexperienced operators can achieve reliable results with the XL3000flex.
An additional advantage of the high gas flow is that it is the only way to enable reliable robotic sniffer leak testing.
LDS3000 Modular Leak Detector
Compact Performance at the Highest Level
With the LDS3000 leak detector, INFICON is opening a new chapter in the success story of leak testing systems. The successor to the LDS2010 is setting new standards for accuracy, reproducibility of measurement results and speed of leak testing.
The LDS3000 is extremely compact. The small dimensions, 13 X 9.45 X 11.1 in. (330 X 240 X 280 mm), make it even easier to integrate it into leak testing systems. More importantly, the space requirements and installation expense have been reduced even further by dispensing with a 19″ control module and improving the cabling considerably. In addition, there is an optional touch screen for easy operation and an optional field bus connection.
INFICON offers a wide variety of calibrated test leaks for almost every application demand.

Leak Tester Calibration
Instrument Recalibration Process
- Our instrument calibration service includes thorough pressure and flow circuit tests to determine instrument accuracy across all pressure ranges
- To ensure accuracy and repeatability, BTD uses the same pressure calibration and flow calibration systems for recalibration that we do for initial in-house equipment calibration
- A specially trained technician performs an inspection and runs the instrument’s self-test cycle to determine the overall condition of your Sentinel instrument
- Each transducer range is digitally recalibrated using a multi-point pressure calibration process and, if equipped, a multi-point flow calibration process
- All pressure calibration and flow calibration is performed with certified gages traceable to NIST standards
- We perform complete instrument system backup to a USB flash drive
- Upon completion, we issue a BTD Calibration Certificate to document “as found” and “as left” specifications
To provide the recalibration service you need without causing undue disruption of your day-to-day operations, we offer both factory and on-site equipment calibration.
For BTD factory equipment calibration, simply disconnect your instrument and ship it back to our manufacturing facility.
For on-site instrument calibration service, our technician(s) will travel to your facility on a scheduled service call. Your instrument remains connected while we recalibrate and recertify its accuracy. A key advantage of on-site equipment calibration is reduced machine downtime—your leak test instrument will be fully recalibrated and back in production with minimal delay.
ONLINE PHARMACEUTICAL CONTAINER CLOSURE INTEGRITY TESTER
The PK-V Machine is designed to perform VDM based closure integrity testing of pharmaceutical vials and bottles by placing them in a vacuum test chamber.
It is fully suitable for both 100% in-line and off-line testing at high production speeds.
The leak test takes place into an airtight testing chamber in which a pressure differential is applied (Patent No. 1225063 of 13-9-1988). The test objective is to detect container leakages by measuring the reached vacuum level as well as the vacuum change over test time.
The leak testing machine measurement system is designed to identify the presence of leaks on containers due to:
- (micro) holes;
- Inappropriate sealing;
