Multi-functional Radiation Detector A two-use tool, can test the electric field and magnetic field radiation simultaneously. Automatic alarm Sound light alarm, when the test result exceeds the safety value , instrument will automatically alarm. Accurate measurement and data lock Built-in electromagnetic radiation sensor, by microchip detection, data lock function, lock with a radiation value button, the value is displayed on LCD display, easy to read. 2 temperature unit measurement Measures ambient temperature - with 2 temperature units (℃ and ℉). Wide application Suitable for measuring machine gen electromagnetic, measure low frequency devices and high frequency radiation devices. Radiation assessment, remind you whether the radiation value is safe or not. Product Description Radiation assessment, remember whether the radiation value is safe or not. Measure the ambient temperature - with 2 temperature units (℃ and ℉).Fashionable design, easy to use in the hand, it is easy to carry and take measurements in the field. One-touch instrument two uses can simultaneously test the electric field and the magnetic field radiation: data lock, one-key lock of the radiation value, and simple reading of the value. Suitable for measuring the generated electromagnetic machine, measure low-frequency devices and high-frequency radiation devices. Audible light alarm, when the test result exceeds the safety value, instrument will automatically alarm.
