Overview
Enviro Testers watch type personal dosimeter is mainly used for monitoring by X and gamma radiation. It caused by individual cumulative dose and dose equivalent rate, could stay wrist like a watch, is more suitable for interventional radiology treatment doses of radiation measurement and alarm, can display real-time data and alarm indication is given, and a data storage, alarm parameters setting, battery voltage detection, wireless charging and wireless data communications, and other functions. Alarm indication is given by Acousto-optic instructions. Its features are compact structure, waterproof and dustproof and can be systematically managed.
