Overview
Honeywell iSeries digital gas sensors are next-generation intelligent sensors that boast a digital interface and five-year operating life. With numerous built-in diagnostic features, the iSeries helps enhance overall instrument performance, making them smarter and safer by indicating faults and monitoring health - thereby decreasing downtime and cost of ownership.
Their ease of integration combined with pre-calibration drives a significant benefit to OEMs and users in terms of integrating the gas detector sensors easily into the instrument.
iSeries multi gas detector sensors target the following gases: carbon monoxide, hydrogen sulfide, oxygen, sulfur dioxide, and combustible gases & vapors. These sensors are often fitted within instruments, such as portable life safety devices and hand-held gas detectors like carbon monoxide sniffers.
With an industry warranty of two years from date of dispatch, Honeywell iSeries simplifies instrument design and speeds development.
