DA-800N Neutron Dose Survey Meter

Product introduction

DA-800N Neutron Dose Survey Meter measuring instrument adopts highly sensitive 3He tube as detector, which has high neutron measurement sensitivity, good gamma suppression performance, small size, light weight, intelligent and easy to operate Convenience and other advantages. The instrument is suitable for neutron radiation detection occasions such as environmental protection, chemical industry, petroleum, medical treatment, import and export commodity inspection, accelerator, neutron source and other security inspection, border control, customs inspection and so on.

Features

• neutron dose rate, cumulative neutron dose;

• With USB data interface.

• 4-inch color touch LCD display;

• Automatically save the accumulated dose, will not be lost when power off, and can manually check the alarm record;

• The alarm threshold of dose rate and cumulative dose can be set arbitrarily;

• 40000 sets of alarm storage data;

• Over-threshold sound alarm, small dead time, high dose rate;

• It has a real-time clock function, which can display the year, month and day in real time, and the operation of the clock will not be affected by power failure.
