The FS-600 is a portable, handheld radiation detector designed for accurate monitoring of X-ray, gamma, and beta radiation. Its compact and lightweight design makes it ideal for on-the-go use in various professional and personal applications. Key features include real-time dose rate monitoring with a clear display and the ability to record cumulative dose values. It offers flexible power options via a built-in button battery or a connected USB cable for continuous operation. The device features an adjustable interface, allowing you to set custom alarm thresholds, select language (English), control screen backlight, and view a real-time dose rate graph. Important data, such as cumulative dose and alarm settings, is retained in the built-in memory even after a power loss, thanks to its efficient 32-bit processor. This detector is suitable for a range of uses including testing decorative stones (like granite or marble) for natural radioactivity, monitoring for industrial nuclear pollution, and assisting in geological surveys. Operation is straightforward: a single button accesses the setting menu to configure alarm presets, time, display options, and audio alerts.
