KJD-2100Radon detectorThe alpha spectrometer is a new type of continuous radon measurement instrument, which is one of the standard radon measurement methods. It uses static electricity to collect radon decay products for cumulative measurement, with high sensitivity, on-site results, small size, and easy operation. It can be used for indoor radon measurement, soil radon measurement, aqueous solution radon measurement, water radium measurement, and other fields.

The KJD-2100 radon detector adopts a single-chip microcomputer system and is equipped with a large screen dot matrix LCD display, which can automatically display and store measurement curves and complete data processing work. Key input, Chinese character human-machine dialogue; Rechargeable battery power supply; Use large capacity non-volatile RAM to store data. At the same time, the instrument can also be used online with desktop or laptop computers, and the Windows fully Chinese operating system makes measurement more intuitive and operation more convenient.
