n Feature Overview

BHC-336Scalers are mainly used for counting and measuring radioactive intensity. It can be connected to a universal gamma scintillation probe, G-M counter tube, or proportional tube probe to measure the intensity of gamma rays; Paired with radon (thorium) detectors (such as FD125), it can measure radon (thorium) gas concentration; Equipped with an alpha or beta scintillation probe, it can measure the intensity of alpha or beta rays; When connected to neutron probes such as lithium glass, 3He tube, or BF3, neutron flux or dose can be measured. Therefore, it is one of the essential tools for applications in nuclear physics laboratories, environmental radioactivity monitoring, isotopes, industry, agriculture, medicine, environmental protection, and other fields. The BHC-336 calibrator consists of a single channel analyzer, calibrator, ARM9 embedded system, etc. Built in low voltage power supply and positive and negative high voltage power supply can conveniently provide high and low voltage power supply for various probes commonly used. Set up a single channel analyzer, use the "differential" mode for energy spectrum analysis, use the "narrow window" to find peaks, and use the "wide window" for measurement; By using the "integral" mode, the integral spectrum can be measured.

n Main technical performance

The design of the instrument takes into account the impact of environmental electromagnetic interference, power grid stability, and changes in environmental temperature and humidity on the instrument; Corresponding electronic measures have been taken. Therefore, even under complex environmental influences, it can still operate normally and stably, overcoming the counting errors caused by external interference on the counter.

The instrument adopts a highly reliable ARM9 embedded system with powerful capabilities for data acquisition and processing. The system adopts high-resolution color display screen and touch function, which is easy to operate. It is easy to set the parameters to be collected and used, such as timing and number, through the touch screen, and save them.

This system has strong communication capabilities with the outside world. It can communicate with a PC through serial port, USB port, and network port, and upload the obtained data to the PC for further processing, storage, and printing. The instrument can also be controlled through the PC

The machine can automatically control high voltage, measure the flat curve of the probe, draw graphics automatically, and facilitate users to determine the optimal working conditions.

This instrument has strong pulse resolution and applicability, with a counting rate of up to 5MHz.
