♥ Welcome to my store "ZWJABYY" ♥The natural environment we live in has a certain radiation, and the real-time data fluctuates within a certain range. Daily use of nuclear radiation detectors helps to avoid radiation hazards in daily life.>>>Specifications:Product Name: Radiation DetectorDose rate range: 0.1 μSv/h ~ 100 mSv/hDose range: 0.1μSv ~ 100SvSensitivity: more than the 1cps/uSv/h (under the condition of Co60 radioactive source)Energy response: 48 keV ~ 1.5 MevRelative error: less than 10% (at 1 mSv/h)Power supply: 2 AA batteries (not included)Power consumption: less than 150mWTemperature specification: -10°C~+50°C>>>Packing list:1 * Radiation Detector (batteries not included)★Note:1. Due to the light and screen difference, the item's color may be slightly different from the picture.2. Please allow 1-2cm difference due to manual measurement.
