High accuracy-0.01Sv/hBuilt in high sensitivity energy compensated Geiger-Muller counter (GM tube), measurement accuracy up to 0.01Sv/h, error 10% (real time measurement) . Retain 3% (average measurement). Multi-function The nuclear radiation detector can measure the dose equivalent of -rays, -rays and X-rays. In addition, if the measured value exceeds the threshold level, an alarm will be issued. It is the best model for inspection factories, hospitals, laboratories, imported products and daily radiation control. Two measurement modesThere are two measurement modes, real-time measurement and average measurement, so you can check the real-time measurement value in emergency and the average value in daily life, and know the radiation amount instantly, depending on the situation. You can use it. * The average measurement value will be displayed after a few minutes of measurement after startup. Backlight, two types of power supply Equipped with a large backlight LCD display, the measured values can be seen at a glance, so you can use it without any problem even in a dark place outdoors. And the real-time value and the average value can be displayed in one screen and monitored at the same time without switching. There are two types of power supply: dry battery and USB, which is convenient anywhere. Portable and easy to useWith its compact size and lightweight design, you can take it with you to any workplace. Since it is a portable type that can easily measure without expertise, it can be easily operated with one hand without any troublesome setup.
