摘要：
Process monitoring systems include a reader having a read sensor, an optional reference sensor, and a light source. The reader optionally includes an optical block defining an interior volume and an aperture aligned with the read sensor to allow diffuse light to be received by the read sensor. One or more percent reflectance values may be calculated in response to a dark measurement, a correction function, and normalization. The one or more percent reflectance values may be compared to a threshold to determine whether a disinfection cycle was effective. The reader may indicate the determination to a user and provide the determination to a tracking system for diagnostics, inventory management, or compliance monitoring.
