DA-60B α, β Surface Contamination Meter
Product introduction
DA-60B type α, β Surface Contamination Meter adopts scintillation detection method. It is used to detect the degree of α or β radioactive contamination on surfaces such as work surfaces, floors, walls, hands, clothes, shoes, etc. in radioactive workplaces and laboratories.
Features
• Can measure α, β γ separately, optional α nuclide identification
• Counter blocking alarm prompt and protection function
• Built-in large-capacity lithium battery, real-time display of battery capacity
• Dose rate alarm threshold setting, over-threshold alarm
• Flashing lights and audible pulse frequency to indicate radiation intensity
• Sound, vibration, light alarm real-time clock function
• Ultra-low power consumption design, real-time indication of battery power
• The detector adopts ZnS(Ag) detector with high sensitivity and fast response
• Backlight function for easy use at night and in low-light environments
• Large-size dot-matrix liquid crystal display, the measurement results are displayed clearly and intuitively Buttons, easy and convenient to operate
• Various alarm thresholds in line with national standards are available, and can also be defined by yourself
• 4GB large-capacity storage can store 100,000 sets of data for viewing at any time, data printing, and communication with the host computer (with analysis software)
• The connection cable between the host and the probe can be extended to 1.5 kilometers, and wireless docking is also possible
• The host has a built-in GM detector to monitor the surrounding environment of the operator in real time
