| Abstract |
Studies on the effect of altitude on 3 personal samplers (MSA Model G, Bendix 3900 and Bendix C115) performed in a vacuum chamber simulating altitudes of 800-16,000 feet (240-4,800m) are described. Pump performance and calibration of the flow-rate meters were both affected by altitude changes. In all 3 cases, the flow rate of a pump unit calibrated for 2l/min at 800 feet increased by approx. 5% at 12,000 feet if not adjusted. If at 12,000 feet the flow was adjusted so that the flow-rate meter float was at the original calibration mark, flow rate increased by 10-23%. Equations for the empirical relations so derived are given for each sampler. |
