定标器是用来记录核辐射脉冲数目的一种仪器。它与计数管探头,闪烁探头等探测器配合,进行放射性强度测量。通过数码显示设备将所记录的结果显示出来,比较相同时间内记录到的脉冲数目,就可以了解核辐射射线强弱情况。射线愈强,在相同时间内所记录到的脉冲数目就愈多;射线愈弱,在相同时间内,所记录到的脉冲数目就愈少。 Scaler is used to record the number of nuclear radiation pulse instrument. It counter with the counting tube, scintillation probe and other detectors, for radioactive intensity measurement. Through the digital display device will record the results displayed, comparing the number of pulses recorded in the same time, you can understand the situation of nuclear radiation intensity. The stronger the ray, the more pulses are recorded during the same time; the weaker the ray, the fewer pulses are recorded at the same time.
