Multi channel analyzer: 1024 channels

Energy resolution:<3.5% (137Cs)

Data collection and processing:

Data collection, communication, processing and display terminal: 4-inch display screen, touch screen operation, built-in data acquisition and processing software.

On the basis of energy spectrum and particle arrival time analysis, nuclide identification is achieved.

Nuclide identification: Nuclide identification is based on spectral analysis methods, and users can configure a nuclide library.

When measuring samples with a dose rate greater than 1uSv/h, the sample nuclide can be correctly identified within 1 minute.

Working conditions:

Temperature: 0-40 ℃, humidity: not exceeding 90% (30 ℃)

Built in rechargeable Li battery power supply, with a continuous working time of not less than 24 hours.

Weight and size:

Weight: 4Kg

Size: 260X230X260mm
