The neutron survey meter is a handheld neutron radiation monitoring instrument primarily used in locations where high-energy X-ray machines or neutron generators produce neutron radiation. ³He gas responds well to neutrons, enabling the detection of neutron dose rates in the environment.

Overview

The YD-900 Neutron Ambient Dose Equivalent (Rate) Meter/Neutron Survey Meter employs a highly sensitive ³He tube as the detector, offering advantages such as high neutron measurement sensitivity, excellent gamma suppression, compact size, lightweight design, intelligence, and ease of operation. This instrument is suitable for environmental protection, chemical industry, petroleum, medical fields, import and export commodity inspection, accelerators, neutron sources, and other security inspection, border control, customs detection, and other scenarios requiring neutron radiation detection.

Performance Features

■ Neutron dose rate, neutron cumulative dose;
■ Equipped with a USB data interface.
■ Features a 3.5-inch color touch LCD screen with a full Chinese operation interface, making it user-friendly and easy to operate.
■ Automatically saves cumulative dose, retains data during power loss, and allows manual viewing of alarm records;
■ Alarm thresholds for dose rate and cumulative dose can be set arbitrarily;
■ Stores 4000 sets of alarm data;
■ Audible alarm when exceeding thresholds, short dead time, high dose rate capability;
■ Includes a real-time clock function, displaying year, month, and day in real time; power loss does not affect clock operation.
