The Tango uses sensor redundancy, reducing the likelihood of the monitor’s inability to detect gas. Below is a chart that shows the monitor failure rate of a single sensor monitor versus a monitor with DualSense Technology when bump tested daily or not bump tested at all. In either case, the Tango elevates the level of safety regardless of the customer’s current bump test policy. Single-Sensor DualSense Technology Daily Bump Test Failure is 1 in 1,265 Failure is 1 in 116,257 — 92 Times Safer No Bump Testing Failure is 1 in 286 Failure is 1 in 21,319 — 74 Times Safer * This bump test failure data is based on records collected through iNet, Industrial Scientific’s gas detection subscription service.
