Portable Single Gas Detector

SST1 Serviceable offers one of the most cost-effective solutions on the market. Equipped with a replaceable 3-year battery life and solid-state polymer sensor technology, the SST1 is presented in a compact and modular design while maintaining its rugged character. With NFC capability, the SST1 can be easily configured to meet your needs and paired with the WatchGas app. SST1 monitors low, high, short-term exposure limits (STEL) and time-weighted averages (TWAs) to provide real-time indication of the risk of toxic gases and long-term exposure. In addition, the SST1 platform can be scaled to monitor up to 8 different gases, making it the ideal solution for your application needs.
