The BW Clip4 (photo) is a new four-gas, portable monitor that can operate continuously for two years without the need to change sensors or charge batteries. BW Clip4 monitors significantly reduce maintenance costs associated with fleets of portable gas detectors by eliminating repair work and the need to stock additional sensors and spare units. Because it is always on, the BW Clip4 helps drive safety compliance by assuring that workers wearing the device are protected. Using non-dispersive infrared (NDIR) technology, the BW Clip4 reportedly consumes 1,000 times less battery power than a catalytic bead (pellistor) sensor, the traditional technology used to detect flammable gases in a portable device. Other features include the following: simultaneous monitoring of H2S, CO, O2 and combustibles; realtime display for instant gas readings, even in non-alarm conditions; and internal test functions that alert users when the unit should be replaced. — Honeywell Analytics, Inc., Lincolnshire, Ill.
