Vac Checker® Precision Digital Vacuum Gauge

High precision digital vacuum gauge specifically developed for highly sensitive testing of vacuum bags and vacuum equipment in composites applications. Vac Checker can be used to perform a reliable vacuum 'drop-test' in a fraction of the time of a typical mechanical instrument.

Vac Checker is a high precision, full scale digital vacuum gauge that will prove itself to be an invaluable tool in the professional composites workshop. Specifically developed and specified for composites use by DD-Compound and manufactured By Testo, this is an incredibly rugged instrument that allows vacuum drop-tests and system diagnostics to be performed significantly more quickly than using typical mechanical instrumentation.

The Gauge can be toggled to display vacuum in most of the common scales: mbar, Torr, mmHg, inHg, Micron, Pa, hPa and inH2O.

Along with the vacuum level it also displays the boiling point of water this is a useful feature as when the vacuum level increases the boiling point decreases, on large infusion stacks there is often a stall in the vacuum pull down around this boiling point as the laminate dries out, knowing that it is not drawing past this boiling point will indicate that the stall is likely caused by moisture and not a leak. Not to be confused with similar products intended for the HVAC industry as these will only provide readings at the near-absolute range making them significantly less useful for composites.

Comes supplied with a single hose-tail for 6/8/10mm I.D. hose. This is for the most common line-end connection, if you wish to use the gauge in an in-line configuration a second set of hose-tails can be purchased to provide a connection on both sides of the instrument.

Typical Use

The Vac Checker is typically connected to one of the resin feed lines in resin infusion to a flying hose and quick-release coupling for prepreg processes, the checker can be used to monitor the vacuum pull down, once the vacuum level has stabilised a drop test can be performed by isolating the vacuum pump and monitoring the vacuum level, the precision on the digital gauge will show a drop in vacuum in under a minute where a traditional mechanical gauge requires the test to be performed over 30mins or more for reliable results.

This gauge can also be used to periodically check the performance of vacuum pumps and the integrity of centralised vacuum systems and peripherals such as degassing chambers and catch-pots.

Leak Flow Indicator

Our simple but effective Leak Flow Indicator will be spun by all but the tiniest leak in a vacuum bag; speeding up bagging and alerting to new leaks if and when they occur.

Traditional Vacuum Gauge

We carry a high quality, glycerine filled bottom entry vacuum gauge and rear entry vacuum gauge suitable for reading the vacuum level on vacuum pumps, bags and equipment. Although these manual gauges do not have the precision and resolution of the Vac Checker, they do provide an accurate and instant indication of overall vacuum level and can still be used to provide a reliable drop-test albeit, over a longer period.
