Abstract

A battery-portable respirable aerosol sensor has been experimentally evaluated. Calibration procedures are described. For instruments calibrated with welding smoke, test results show agreement within +/- 15% of parallel filter samples for 10 laboratory and industrial aerosols including welding and tobacco smoke, oil mist, cotton and asbestos mill dusts, powdered metal and walnut shell dusts, and atmospheric urban aerosol in the 0.05-5.5 mg/m3 range. Results show that an average of several piezobalance measurements can accurately simulate a time-integrated filter sample in many industrial environments.

摘要

已对一种电池供电的可吸入气溶胶传感器进行了实验评估。描述了校准程序。对于用焊接烟雾校准的仪器，测试结果表明，在0.05 - 5.5毫克/立方米范围内，包括焊接烟雾、烟草烟雾、油雾、棉尘和石棉厂粉尘、金属粉末和核桃壳粉尘以及城市大气气溶胶在内的10种实验室和工业气溶胶，与平行过滤器样品的测试结果在±15%以内相符。结果表明，在许多工业环境中，多次压电天平测量的平均值可以准确模拟时间积分过滤器样品。
