Calibrator for leak testers T2710

Checks at the production line

The T2710 is made for periodic checks and calibration of leak and flow testers. There is no need to take testers to a laboratory: the calibrator runs on a rechargeable lithium-ion battery and, at 180 × 80 × 35 mm and 700 grams, fits in a toolbox. Besides acting as a reference for other instruments, you can also use it as a stand-alone meter, for example to measure an actual leak on a part or to check a reference leak.

Mass flow measurement

The T2710 measures with a thermal mass flow sensor. This measurement does not depend on pressure or temperature changes and gives values at the reference conditions of 0 °C and 1013.25 mbar, without correcting afterwards. The sensor responds quickly, which makes fine adjustment of the micrometric valve easy. The measuring system uses a resolution of 1 million AD points as standard.

Two versions

The version up to 30 cc/min measures with a resolution of 0.01 cc/min and is meant for very sensitive applications such as medical devices, precision valves and hermetic electronics. The version up to 200 cc/min has a resolution of 0.1 cc/min and suits most applications in automotive, hydraulics and pneumatics. If you need a larger range, ForTest can supply the T2710 for up to 1000 cc/min on request. The accuracy for that range is given in the quotation.

Simulating a leak

The T2710 comes with a micrometric valve. You connect the calibrator in series with the valve to the pressurised system and open the valve until the T2710 shows the leak value you want. This simulates the target leak exactly, so you can check that the leak tester measures that value correctly. A standard and a precision micrometric valve are available; the precision version adjusts more finely and holds its setting more steadily.

Recording measurements

Through the USB connection you transfer the recorded measurements to a PC. You can then add them to calibration reports and keep the traceability your quality system requires.

Combining with a reference leak

If you want a fixed reference that needs no adjustment, use a certified reference leak: the T0710 for small leaks or the T0730 for larger flow rates. For higher flow rates, ForTest offers the T2730 calibrator: 5 to 20 l/min as standard, up to 200 l/min on request.
