Does anyone else make something like the Vapor Pin® sampling device?

We’re not aware of another device quite like the patented Vapor Pin® sampling device. Other types of sub-slab sampling devices installed with cement are available, and some practitioners construct their own from plumbing parts. But the cost of locating parts, problems with leakage, and the fact that once installed, they normally can’t be reused, makes them more costly in the long run. We believe the Vapor Pin® sampling device will become the new standard for sub-slab vapor sampling because it’s easy and quick to install and use, it can be used over and over, and it provides quality samples with little or no leakage.
