Honeywell announced the launch of the Signalpoint Pro, an Intrinsically Safe (IS) certified gas detector that offers a low-cost solution for the detection of toxic and oxygen gases in potentially explosive atmospheres worldwide. It is designed for a wide range of indoor and outdoor applications, detecting toxic gases or Oxygen in an IS 2-wire 4-20mA format. This wiring configuration makes the detector particularly suited for retrofitting other 2-wire IS devices including the Sieger Series 2000 range of two-wire IS toxic gas detectors. The device offers high reliability and ease of use; its smart gas sensors are automatically recognized when plugged into the detector and access to the sensor does not require opening the main terminal housing. This reduces down-time during sensor replacement procedures.
