CH286-05

CH286-05 β detector is a counting detector for measuring low energy β-rays. It is applied to environmental monitoring, atmospheric pollution monitoring, precise measurement and analysis, higher education, scientific research and thickness measurement for its low noise and wide dynamic range.

CH286-05 β detector has the advantages of simple and convenient use, high reliability, not easy to damage, long lifetime and high detection efficiency.

This product can directly output TTL signal with fixed pulse amplitude and width to facilitate signal acquisition and processing. Before the detector leaves the factory, each parameter has been preset as the optimal value. The user only needs to provide +12V power supply within the required range, connect the detector and the power supply module, and connect the output signal terminal to the pulse counter for counting application.

1) Test with 14C with activity of 60μCi (Source distance detector 2mm);

2)Test process of Instability for 1 hour: The counting rate collected by the detector is 6.0±0.5ks-1, each data collection time is set to be 4min, each group of data is accumulated to collect 15 data (1 hour), the absolute value of deviation between each value in each group of data and mean value is calculated, continuous 3-group test (3h) is conducted, and the maximum value in the 3 groups is taken as 1 hour instability test value;

3) No dew condensation.
