plugging in to readings on a CellSensor

Hello. I'm new to arduino and I'm trying to figure out how to send readings from a CellSensor emf/rf reader to an arduino. The readings are expressed in milliWatts per square centimeter. Does anyone have experience with hacking this product?

Thank you!

Depends if you are prepared to open it up to get a connection to the internal analogue meter. It wouldn't take much doing if you opened it up and established how much voltage its feeding to the meter and then a voltage divider maybe to an analogue pin on the arduino and a common ground.
