SST1/SST1E Serviceable Models
SST1/SST1E Serviceable
Single Gas Detection
WatchGas SST1/SST1E serviceable single gas detectors offer a broader range of target gases. Typically up to 23% lighter and smaller than comparable detectors and equipped with a replaceable sensor and battery. These detectors stay in your fleet well beyond the impressive 3-year battery runtime. Delivering the lowest cost of operation in their class, these serviceable detectors are ideal for industrial plant operations and fleets of any size. Two models, multiple gas options. Each developed from a real customer need. Scroll to learn more.
- Prevent toxic gas exposures with earlier sensor warnings – up to 20 extra seconds to evacuate
- Up to 67% less test gas consumption can save you 1000s and reduce testing bottlenecks
- Built in preventative cumulative background exposure / leak awareness
- Better visibility for quicker decisions – typically 54% larger display than comparable detectors
- STEL & TWA Alarm Readings
Description
