Features:

The actual application of HD2001 is a multi-channel y-spectrometer with 2048 channels

2. It has four major functions: powder sample measurement, non-destructive sample measurement, air hydrogen measurement, and soil hydrogen measurement

3. Full wave acquisition, no pulse leakage meter, with intelligent functions such as baseline correction and interference recognition. PMT output signal is straight through, waveform distortion free, and consistent resolution can be measured by placing C5 peak at any channel address within the measurement range

4. Maximum data pass rate:>333Kcps, high-speed transmission, no data leakage count

5. Visual measurement display, with functions such as signal waveform, baseline online monitoring, and real-time analysis of measurement results

6. Equipped with peak position monitoring function to ensure data collection quality

7. Comprehensive analysis and spectral analysis of characteristic spectral segments, full spectrum testing, multi spectral line comparison, and other functions can be used for scientific research, teaching, and technical training

8. Electric structure lead shielding room, saving time and effort when replacing samples
