Five PosiPatches are included with all PosiTector SST PosiPatch Kits. These kits include everything required to begin measuring with the innovative PosiPatch. While they are reusable, PosiPatches may eventually wear out or become dirty after extensive testing. Replacement PosiPatches are also available:
PosiPatches (24) - for use with PosiTector SST PosiPatch Kits
PosiPatches (5) - for use with PosiTector SST PosiPatch Kits
DeFelsko Adhesive Patches (25)
Latex Adhesive Patches (25)
The DeFelsko Adhesive Patch is similar to conventional Bresle Method patches and features a low-tack adhesive, making it easy to remove with no residue to clean. It is latex-free, and therefore significantly less expensive than conventional patches.
For users who require a patch with latex construction (which can expand to a 15 ml sample size), we offer the DeFelsko Latex Patch. It also features a low-tack adhesive and TearGuard™ technology for easy patch removal that leaves no residue to clean. Additionally, it features an easy-to-remove tab on the paper backing.
One of the many innovative features of the PosiPatch is its ability to be reused multiple times by rinsing with DI water between tests. The PosiPatch can be used repeatedly until water begins to leak through the air‐permeable membrane or the seal against the substrate. In our tests on freshly blasted steel with a typical 50‐100 micron (2‐ 4 mil) profile, PosiPatches were reused dozens of times with no noticeable wear or leakage. Patch life will vary depending on use ‐ if dragged along the substrate, lifespan will be reduced. We believe that 10 uses is a very conservative estimate of lifespan and still yields the lowest per‐test cost of any commercially available Bresle Method Patch.
Yes. The PosiPatch is ideal for use in any orientation. When used on vertical surfaces, position the injection port at the 6 o’clock position before attaching the ring to the surface and insert the dispensing tip only as far as is needed to see the tip inside the PosiPatch.
Yes! The flexible PosiPatch is designed for multiple uses on typical rough surfaces and maintains its watertight seal for a simple, leak-free test.
Yes. The Bresle Method PosiPatch is ideal for measuring on flat and curved surfaces.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
The innovative PosiPatch uses a magnetic ring to hold it against the surface, so no adhesive is required. This means that the PosiPatch isn’t destroyed when removed from the surface, unlike conventional patches. After rinsing with deionized water, the PosiPatch can be used again.
