Scigiene's Gen 2 Wireless Hydrogen Sulfide (H2S) Sensor measures the levels of toxic H2S gas in the environment. The sensor produces instantaneous and 8-hour time weighted average (TWA) H2S readings along with temperature. Every five seconds the sensor takes a new temperature-compensated H2S measurement and checks this measurement against a configurable threshold. If the threshold is crossed, the sensor transmits data immediately. This means the sensor can report a critical gas level as soon as it's detected. If the threshold isn't crossed, the sensor transmits H2S data at a configurable Heartbeat. Using configurable Actions within Scigiene Premier Software, you can set up notifications to be sent via text, email, and phone call as different triggering events occur - gas level, battery level, inactivity, etc. The instantaneous reading is calculated using 40 seconds of data averaged together for improved stability and accuracy. The TWA reading is calculated using eight hours of data.
