Thank you for sharing your experience with your devices. Blushield is not a blocking or shielding technology, so it won't affect the readings of an EMF meter. Blushield provides protection directly at the cell level of living organisms, by producing a biologically coherent competing field that the body preferentially entrains with.  It exists alongside the EMFs emitted by your other devices (including cell phones and Wifi), but the Blushield gives your body a healthier option to resonate with, which removes the majority of the biological harm from the other EMFs.

There are currently no devices we are aware of that measure can scalar fields. We designed the devices so that if the light on the device is on, that means it's working properly. This is because the light is the very last part of the circuit, so if any other component in the circuit became defective or stopped working, the light would shut off automatically.

If you're asking how you can tell that Blushield is working to protect you from EMFs, you will need to directly observe biological effects. Many people feel a difference immediately, or within the first couple of weeks.  The differences can be subtle, or more dramatic in some cases.  Some people feel nothing at all, because the changes are happening at the cell level and many people can't feel that tangibly, similar to how most people can't tangibly feel the harmful effects of EMFs.

Most people will not want to do more extensive biological tests on themselves, which is why we conducted a clinical trial on our products a couple years ago. It is an independent review board certified, peer reviewed clinical study on 25 adults, which showed statistically significant improvements in several areas related to health and well being.
