  • December 2013: Robert Nepper reports that they have made improvements to the SuperWAPI, which features a heat resistant stainless steel cable. North Star Devices' WAPI is the only WAPI offered as a hammer together design, not requiring heat sealing. The SuperWAPI is also now available as a kit. Read more about their WAPIs in their latest flyer: Reusable Water Pasteurization Indicators (WAPIs)
