JA33003 Surface Pollution Monitor

JA33003 is an instrument that can simultaneously measure the surface activity of α and β. It can measure the activity value, count value, or specific activity of selected nuclides. When the measured value exceeds the pre-set alarm threshold, an audible and visual alarm will be given. It is suitable for environmental protection, public security, customs, health, and scientific research institutes.

Features:

Can measure both alpha and beta simultaneously without the need for an external probe

β background monitoring and compensation, alarm threshold can be set

Adjustable measurement time

Large OLED display screen

Large detection area: 170cm2

A user-friendly interface that only requires 5 key operations
