Has anyone used this (or any other potassium meter)? I'm wondering how long the sensor lasts (I notice you can buy replacement sensors).
Also, are readings expected to be higher/lower at certain times of day? Eg when you first wake up?
I sent emial to Charles Weber who is a potassium expert - he might know. Stay tuned. There is also a club in Britain who take potassium supplements to treat arthritis - some Charles Cote group. They might know. I'll see if I can track them down as well.

But it SAYS on the manufacturers site: *This product is not approved by Horiba for personal medical use
It is for soil science.
Oh, but at this site it says: The C-131 Cardy potassium ion meter is not currently approved for medical use by the FDA, nor is it sold as a medical device, but it is very sensitive measuring device which has given excellent results to the patients in our group who have used it.

It's pricey. But we really need something if we are going to try to help others with this protocol. Other people are stupid about their health and symptoms and especially if they are on pain-killers may not even notice key symptoms.
PLEASE NOTE - as with ALL measurement equipment, it can go out of calibration and MUST be periodically checked to ensure it is correctly calibrated. Here is a site selling solutions of known potassium concentration for calibrating the meter:

Looks like people with periodic paralysis use it:

They say: Test results are not accurate enough to be used for diagnostic purposes. They are intended to be used for monitoring purposes and to determine patterns of potassium levels/shifting as seen in conditions such as periodic paralysis. Used in conjunction with urine pH levels will give a broader picture of the potassium levels in conjunction with the acid/alkaline levels. This information might be helpful to diagnose conditions such as periodic paralysis when used in conjunction with other diagnostic tests and devices. Standardized laboratory tests should be conducted before making any diagnosis or before administering any medications or supplements to address the effects of hyperkalemia and hypokalemia or potassium shifting.
