              TQC Ltd 
              specialise in the supply ofautomatic 
              leak testing machines 
              & leak test systems.
 The requirement may be for a standard leak 
              testing application or a special purpose leak test machine. TQC 
              combines standard leak test instuments and TQC designed fixtures 
              to provide the best solution to suit the customer specification. 
               This test machine capability is enhanced 
              by our experience in automated production line equipment and process 
              automation resulting in a complete service to industry. 
             Leak testing is a niche area of engineering, 
              sometimes referred to as pressure testing or vacuum testing. TQC 
              has the knowledge and expertise to assist the customer in specifying 
              the acceptable leakage rate, or leak limit, and in designing and 
              supplying the leak test machine to reliably test how much an item 
              is leaking..  Different forms of leak testing equipment 
              supplied include, manually loaded QC test benches to fully automatic 
              leak testing machine for 100% testing. Test methods provided include 
              pneumatic leak testing, air decay leak measurement, pressure decay, 
              vacuum decay, high vacuum, helium leak testing and water submersal 
              or dunk tank systems for visual leak location..
