Product Sheet

Speed:
Advanced electronics, revolutionary calculation algorithms and optimization of the pneumatic circuit allow to execute tests in very short times.

Precision:
Measure resolution over 100000 points on end scale, measure uncertainty inferior to 0,5%.

Connection:
ET07 is able to connect with PC, VISUAL BOX, PLC, automatic and semi automatic stations and FOR TEST© accessories.

ET07 is actually the most compact leak test instrument in the world. Although it is an instrument with very reduced dimensions, in performance terms it can be absolutely compared with the most complex and big leak test systems.
The instrument detects leaks, taking advantage of the “pressure drop” principle (this method is recognized by UNI EN 1779): at the beginning it pressurizes the piece and after an arrangement time, it finds the pressure decay.
The leds which are set on the superior part, give information about the condition and the results of the test, the connector allows us to manage the test through remote controls or to connect with a PC for manage till 10 ET07 or a VISUAL BOX, a central unit which manages till 4 ET07.
The reduced dimensions allow the instrument installation near the element to test, to reduce the parasite volumes and guarantee the best test conditions.
The compactness and the possibility of a real-time management and the independent way until 10 test stations, make ET07 the ideal application in the multi-test inspection stations.
