Features:High detection performance: ultra-fast detection and low measurement error, the instrument can measure the local radiation value.High sensitivity: high data accuracy. When the dose rate radiation dose exceeds the threshold, an audible and flashing alarm is automatically issuedVersatile: Radiation levels can be detected at any time in any environment or any environment. Examples include radiation detection, antiques, building materials, furniture, food, etc.Large display: There is a visual display, so that users can clearly see nuclears radiation datas.Portable design: small size, hand-held design, easy to carry.Notice:1.Actual color may be slightly different from the image due to different light effect2.Please allow 1-3cm deviation due to manual measurementDescription:Size:8.8x4.3x1.9cmSensor: GM-counter tubeMeasuring range: 0.08usv-50msyMeasurement accuracy: 17%~+25% based on csyWorking environment: temperature -20C~50C; Humidity <95%RH No condensationBattery life: about 15 days (continuous measurement, no particles sound)Charging interface: TYPE-C interface (when charging, the green-light is steady on, full off) alarmResponse time: <10s alarm threshold deviation :17%~+25%Weight: 180gProduct size: 8.8x4.3x1.9cmPackage size: 15.4x11.2x2.8cm
