F28 LIGHT
HIGH SPEED LEAK TESTER
FOR INDUSTRIAL QUALITY CONTROL

Without any doubt, the smallest high performance leak tester on the market. One of the main advantage is that our F28 Light module can be mounted close to the test part, ensuring the best measurement conditions. You can daisy chain up to 50 modules and supervise them with a touch screen panel + our user friendly interface : F28 light demo.

Specially adapted for automatic and semi automatic test machines, the F28 Light has a full range of specifications at a very competitive price.

F28 LIGHT : TECHNOLOGY

By far the most popular technology, differential pressure decay uses a reference volume to test your part. This helps compensate for any ambient pressure or temperature variations as they occur on both parts simultaneously.
Only a leak on the test part will result in a movement of our transducer’s membrane.

The second advantage of this method is that the accuracy does not drop with the test pressure as the transducer is measuring pressure differences between the two circuits, as opposed to the traditional pressure decay technology that measures pressure drops against the atmosphere.

Direct measurement principle
The part under test 3 and the reference part 5 are filled to an identical pressure. A differential sensor 4 measures the pressure variation between the part under test  3 and the reference part 5. In some applications, the reference part can be replaced by a cap.

Desensitized test
This  mode  is  used  for  the  measurement  of  large  leaks,  when  the  reject  level  required  is above the full scale of the differential sensor.
The  test  pressure  is  applied  to  the  input  of  the  part  under  test  3.  The  measurement  is performed by the pressure sensor 2.

Other type of tests are available in option
