摘要：
A respirator service life indication system may include a breathing apparatus having an air purifying element; and a service life indicator arranged in a parallel flow configuration with the breathing apparatus. The service life indicator typically might have a sacrificial cartridge, and a sensor disposed downstream of the sacrificial cartridge and configured to detect a contaminant concentration above a predetermined threshold in a gas stream passing through the sacrificial cartridge.
