Industrial health and safety equipment manufacturer Sensidyne released the SensAlarm Plus, an all-in-one gas detection system for monitoring oxygen, toxic, and combustible gases. The system functions as a single transmitter that offers “Test-on-Demand” and “Predictive Sensor Failure” features, in addition to accepting oxygen, electrochemical, catalytic bead, or infrared sensors. The system provides a large LED display of gas value and a backlit LCD displaying system settings, data review, sensor information, and visual and audible alert annunciators. SensAlarm Plus is available with single or dual strobes and comes standard with a loud audible annunciator. A battery back-up option provides power to the unit in the event of power failure for up to 60 minutes in standard monitoring or 30 minutes in full-alarm mode. (
