A general purpose high accuracy dosimeter reader, 80 , for determination of a treatment condition, based on comparison of an image of treated dosimeter, 111 , with a series of images of pre-treated dosimeter, 114 , is disclosed. A dosimeter undergoes noticeable changes, such as a color change upon treatment with certain materials, such as toxic gases and processes, such as ionizing radiation and sterilization is pre-treated. The dosimeter is imaged with an imaging device, 115 , such as charge-coupled device camera and images of the dosimeter or the changes, e.g., color change, are stored in an information storage device, 118 . In order to determine the treatment condition, the treatment dosimeter is imaged and the image is compared with the series of pre-treated images of the dosimeter using software. The closest match of the treated dosimeter with the pre-treated and pre-imaged dosimeter would indicate the treatment conditions. The process and device can be used for almost any indicating device, process and treatment.
