NT6101-S75 environmental grade X and gamma radiation inspection instrument

Product Introduction

X. The gamma radiation air specific release energy (absorbed dose) rate meter uses large-sized plastic scintillators as detectors, mainly used for measuring radiation X and gamma air absorbed dose rates in low radiation environments, as well as searching for radiation sources. Applicable to environmental protection departments, disease control centers, geology and mining, medical and health, nuclear power plants, public safety and nuclear emergency, national security, military customs and entry-exit inspection and quarantine, civil aviation, railways, highways and shipping, nuclear decommissioning and decontamination departments.

Features:

-The detector adopts a 3 × 3-inch composite plastic scintillator, which has high sensitivity and fast response speed;
-The host is equipped with a GM detector, which is used to measure the cumulative dose of radiation to the operator;
-The measurement time can be selected from 1 to 600 seconds as needed;
-Adopting the internationally unified units nGy/h (environmental grade) and nSv/h (protective grade);
-Large size dot matrix LCD display with backlight function;
-Lithium batteries with large capacity and charge discharge protection function;
-Real time display of battery level and undervoltage alarm function;
-Touch sensitive buttons;
-Dose rate alarm function with secondary alarm threshold;
-Detector malfunction alarm function;
-Real time clock display;
-Overload alarm function;
-Can save 200 million pieces of data and have real-time viewing function;
-The shell is made of aluminum magnesium alloy;
-The probe is equipped with an anti slip handle, and the host is fixed on the probe;
-Equipped with programmable sound, flashing, and vibration alarm functions;
-USB data read and transfer function;
-Optional Bluetooth and Bluetooth printer.
