Product Overview

The HA9001 is an electronic instrument designed for counting and analyzing output pulses from radiation detectors. It integrates functional modules including a linear amplifier, single-channel analyzer (SCA), multichannel analyzer (MCA), low-voltage power supply, and high-voltage power supply. With abundant I/O connectors on the front and rear panels, it connects to common radiation detectors such as GM tubes and scintillation probes to form α/β counting systems, γ intensity measurement setups, and gamma spectroscopy systems. It is widely used in nuclear electronics experiments, radiation protection education, nuclear physics research, radiological hygiene monitoring, nuclear power plant inspections, nuclear industry measurements, nuclear detection training, and radioactive aerosol analysis.
