α. β Surface Pollution Monitor

α. β Surface Pollution MonitorAdopting a dual flash detector with high detection efficiency, the same probe can simultaneously measure alpha and beta particles and automatically distinguish between them. It is an ideal instrument for detecting alpha and beta surface contamination in environmental laboratories, nuclear medicine, molecular biology, radiochemistry, nuclear material transportation, storage, and inspection. This instrument adopts single-chip control, which can achieve continuous data acquisition, storage, and can be queried at any time.

α. β Surface Pollution MonitorTechnical Features

1) The same probe can simultaneously measure alpha and beta particles and automatically distinguish between them

2) Equipped with over threshold and fault alarm indication functions

3) Adopting microcontroller technology, it has multiple functions, small size, simple instrument operation, and easy use

4) The probe host adopts a split structure, and the host itself is a gamma ray measuring instrument/personal dose alarm device

5) RS485 interface is used between the probe and the host to achieve long-distance data transmission

6) Low power consumption and long standby time

technical indicators
