describe:LCD digital electromagnetic detector dosimeter tester instrumentation equipment:.One machine with dual functions, can test electric and magnetic field radiation at the same time, and send out an alarm light. When the test result exceeds a safe value, the instrument will automatically alarm.Data lock, lock the one-key radiation value.The LCD displays the value for easy reading. Radiological assessment, remember whether the radiological value is safeStylish design, easy to operate by hand, easy to carry and measure on siteSpecification:..Color: orange + black Material: unit plastic: V/m (electric field); uT (magnetic field)Accuracy: Electricity: 1V/m; Magnetic: 0.01TRange: Electric: 1-1999V/m; Magnetic: 0.01-19.99T Alarm threshold: Electric: 40V/m; Magnetic: 0.4TDisplay: 3-1/2 LCD displayBandwidth test: 5Hz-3500MHzSampling time: about 0.4 seconds Test mode: simultaneous dual module test over-range indication: LCD display ""1""Working temperature: 0C-50CHumidity: relative humidity <80%Power supply: 1*6F22 9V battery point size: 12.5*6 * 3cm / 4.92 * 2.36 * 1.18in (L * W * H)Item weight: 109g / 3.84ozPackage content: 1 X electromagnetic radiation detector1 X User Manual (English)1 X retail packaging.5hz-3500MHzSampling time: approx. 0.4 second test mode: simultaneous dual module test over-range indication: LCD display ""1""Working temperature: 0C-50CHumidity: relative humidity <80%Power supply: 1*6F22 9V battery point size: 12.5*6 * 3cm / 4.92 * 2.36 * 1.18in (L * W * H)Item weight: 109g / 3.84oz packagingContent: 1 X Electromagnetic Detector
