HF-B3G Triple Axis HF RF Meter Analyzer and Detector 50MHz - 3.5GHz Measuring EMF Radiation from Cell Phones Smart Meters Cell Towers WiFi

Q: What kind of battery does this use? Is it internal and rechargeable or do you place the batteries inside and if so, what size / type battery? Thanks

I am sorry for the delay in my answer. This device uses regular 9v battery (comes with it). You can use any rechargeable 9v battery. But, before you buy this device, I need to let you know that I find it to be no so accurate. The numbers keep jumping up and down, in high values, making the device useless. It has a way to lock on the max value, but does not show the real time number. I am going to send the supplier an email asking them if this is expected. I used to have an analog one, and it showed some small/ minute variation in readings, but still manageable. I bought this digital device, because I thought I can get a better, accurate reading. This might be more detail than expected, but hope it is useful.

Q: Does this emit any kind of rf itself? i am highly sensitive to wi-fi radiation. it effects my heart condition. so can't have anything that emits it

Hello,The RF Meter is only measure the RF signals. It does not emits RF.

Q: Will this meter measure the frequency from a high voltage power line running in front of our land? Need to know how far to build for it to be safe.

Hello, The HF-B3G won't measure low frequency EMF. In order to do so we recommend you using the MG-300 or the MG-2000T. https://www.amazon.com/dp/B01CGVBP5O https://www.amazon.com/dp/B01HQBRZ9O

Q: Why are reading alot higher when held in my hand versus setting on table (ball not touching anything)? also why read higher on Y axis?

Hello, The reason for higher reading might be that your body serves as an antenna or a reflector of the signal back to the meter. Please ensure that your cell phone turned off when you do the measurements.
