The Pro-Tek passive colorimetric air monitoring badge for personal or area sampling of hydrogen sulfide is described. The badge has been validated over the range of 1.8 to 164 ppm-hours (0.23-21 ppm on an 8-hour TWA basis). It has an overall accuracy throughout this range of +/- 15.9% and meets the NIOSH accuracy criteria for an analytical and sampling method. The colorimetric analytical method used is based on the Texas Air Control Board's Molybdenum Blue method. Color-activated exposed badge solutions are read out on a standard laboratory spectrophotometer using 1 centimeter (10 mm) cells. Variations in exposure temperature (between 10 degrees and 40 degrees C), relative humidity, and face velocity (between 2 and 250 ft/min) do not affect badge performance. Unexposed badges are stable for more than 12 months refrigerated and for two months at room temperature.
介绍了用于个人或区域硫化氢采样的Pro-Tek被动比色空气监测徽章。该徽章在1.8至164 ppm-小时的范围内（基于8小时时间加权平均值为0.23-21 ppm）经过验证。在此范围内，其总体准确度为+/- 15.9%，符合美国国家职业安全与健康研究所（NIOSH）对分析和采样方法的准确度标准。所使用的比色分析方法基于得克萨斯州空气控制委员会的钼蓝法。使用1厘米（10毫米）比色皿，在标准实验室分光光度计上读取颜色激活的暴露徽章溶液。暴露温度（10摄氏度至40摄氏度之间）、相对湿度和表面风速（2至250英尺/分钟之间）的变化不会影响徽章性能。未暴露的徽章在冷藏条件下可稳定保存超过12个月，在室温下可稳定保存两个月。
