Read our Guide to Disposable Single Gas Detectors
WatchGas have introduced the SST1 as a maintenance-free single gas detector. This specific model detects oxygen depletion and oxygen enrichment. It’s a personal O2 monitor and is designed to be won on a person, protecting their breathing area, in applications such as oil and gas, contractors, site maintenance, turnarounds, shutdowns, boiler rooms, steel plants, laboratories, shipping, power generation and mining.
The SST1 is able to communicate with smartphones by using NFC technology. This method of communication operates as part of a wireless link and by simply ‘tapping’ your monitor and phone you will be able to connect to the WatchGas app. The app allows you to manage your fleet of instruments, assign monitors, download event logs and bump test your detector.
The WatchGas SST1 is a disposable monitor, so there is no need to replace the sensor or the battery. The range is available with a 2 or 3 year life time depending on the type of gas. This Oxygen (O2) monitor has a 2-year lifetime only.
