Development of Improved Detection Instruments for Toxic Gas Contaminants in Mining Atmospheres.
NTIS: PB/82-256223 :54 pages
The objective of this investigation was to develop improved sensor cells for use in direct-reading detectors and diffusion-exposure meters. A pumped CO sensor cell was developed that has a shorter response time, improved temperature cycle characteristics, and improved linearity and stability at high CO concentrations. Diffusion CO sensor cells showed good response-level stability and linearity up to 1,000 ppm. In addition, a new sensor cell catalyst was developed for NO2 sensor cells that has a much shorter response time and improved response stability characteristcs.
