Description
The SST1 Serviceable offers one of the most cost-effective solutions on the market. With its 3-year replaceable battery and solid polymer sensor technology, the SST1 offers a compact and modular design without compromising its ruggedness. The SST1 Serviceable can be configured to your needs with one simple tap of the NFC and paired with the WatchGas Application. Monitoring for Low, High STEL, and TWA the SST1 will indicate any immediate risks and long-term exposure to toxic gases. SST1 is the platform that will allow us to expand on up to 8 different gases, so this is the ideal solution for your application.
