Designed for use in safety-critical industrial applications, the 4OxLL long life oxygen sensor is designed to work for the whole life of the average portable gas detector. With an operational life of five years, the sensor provides a fast response with less than 5% drift over life. Using the 4OxLL, its maker claims that a plant operating 200 portable gas detectors can save 200 hours of maintenance labor, roughly $20,000 in total, based on $100/hr. labor, over five years, compared with a standard two-year model. This calculation is based on an estimated 30-minute sensor replacement time.
