This device can help you to check whether there is no radiation and constant temperature around the object under test, but it can not directly detect the RF value - MULTIPLE FUNCTIONS --Test the average or peak (maximum) readings, and hold the data for viewing with one key. The large backlit LCD screen is clearly visible and easy to observe. Automatically power off after 5 minutes of inactivity - SOUND & LIGHT ALARM - when the test result exceeds the safe value (> 4.0 mG / > 0.4碌T / > 40 V/M) the screen turns red, the indicator light flashes, and a buzzer alerts you. If you think you it beeps noisily, you can choose to turn it off - LARGER FREQUENCY RANGE WIDER APPLICATION-The use of advanced electromagnetic radiation sensor, frequency range: 5HZ-3500MHz, coupled with accurate measurement chip, so it can be widely used to test TV, computer, printer, microwave oven, refrigerator, cell phone towers, for low frequency household appliances, and ghost hunting, etc. - CUSTOMER SERVICE - strives to create professional and high quality meters. We provide 36 months after-sales service and lifetime technical support. If you have any problem, please feel free to contact us, our professional after-sales team will solve your problem in time.
