FS-600 is a small high-range radiation detector, the main function is to monitor X-ray, -ray and -ray.The detector of this instrument is an energy-compensated Geiger counter (hereinafter referred to as GM tube), which is characterized by accurate measurement and high range.This product uses a 32-bit microprocessor and is equipped with a 64*128 dot matrix LCD display, which is simple to operate and has a strong anti-interference ability.The equipment provides an audible alarm, and the alarm threshold is continuously adjustable. When the alarm threshold is reached, an alarm is issued to remind the staff to pay attention to safety.The main counting indicators of the instrument comply with international standards. Even the product size is designed according to the inspection standard (JJG 1009-2016), and the product has obtained the calibration certificate of the Institute of Metrology (20211105-0891) Function: 1. Nuclear radiation,can detect X, , Ray . 2. Trend graph, Particles sound, Alarm sound, Display sound. 3. Built-in Geiger counter, which is characterized by accurate measurement and high range. 4. Measure the dose rate real-time, and record the cumulative dose at the same time. 5.The dose rate alarm threshold and dose alarm threshold can be continuously adjustable and arbitrarily set. 6.Can view the start date of the current cumulative dose. 7.Have dual alarm functions of dose rate and dose value. 8. With buzzer sound alarm function. 9.When the radiation dose rate exceeds 10mSv/h, it has a blocking warning prompt function (display 999MAX). 10.Built-in memory, the accumulated dose value, dose rate alarm threshold and dose alarm threshold data will not be lost after power off. 11.Continuous monitoring of battery power, Low battery reminder function. 12.With real-time dose rate curve display function. 13.Screen backlight ON/OFF function. 14.Particle sound ON/OFF function. 15.The external Type-C interface can be used for power supply.
