近年来，在线颗粒计数器在饮用水行业的使用有所增加。不幸的是，这些粒子计数器的性能还没有得到充分的验证。与任何其他监测工具一样，粒子计数器的数据仅与设备接收到的校准和性能验证一样好。本文介绍了目前用于校准粒子计数器的各种方法。文中还介绍了在现场成功进行的简单现场校准验证。

Use of on-line particle counters in the potable water industry has increased in recent years. Unfortunately, there has been insufficient verification of the performance of these particle counters. Like any other monitoring tool, a particle counter's data are only as good as the calibration and performance verification which the equipment receives. This paper describes the various methods currently being used to calibrate particle counters. A simple field calibration verification which has been successfully performed in the field is also described.
