Special Report No. 91-01: Laboratory Examination of Several Personal Chlorine Monitors for Use in Pulp Bleach Plant Workplace Atmospheres

The performance of personal workplace atmosphere chlorine monitors available from COMPUR, Neotronics, Interscan, MDA, and ENMET was examined in the laboratory. All monitors required calibration before use and responded quickly to 5 ppm chlorine. Significant differences in other factors were recorded, including span drift, response to chlorine dioxide, effects of temperature and humidity, and response to sulfur gases.
