The first stencil moisture meter, the TQM™Aqua-Check™ determines when the stencil is dry enough to expose. Our exclusive TQM Aqua-Check meter detects hidden moisture instantly. It is a fast and accurate measurement that prevents you from having to take chances with your stencil. The battery-operated contact meter provides direct readings of the residual moisture content in coated (and dried) screens to ultimately prevent pinholes and premature stencil breakdown. A screen that is not dried thoroughly before exposure will not harden effectively, and is vulnerable to these deficiencies. The Aqua-Check’s modest cost can save you big outlays in press downtime and stencil remakes. For use on polyester and nylon screen mesh. There’s no guesswork. Simply hold it against the emulsion or film surface and press the “Read” button for 2 seconds. Red for trouble ahead. Orange for risky. Green for go!
