I need a few opinions about what TDS ppm meter, in the mid price range, is best to use for soil potted plants. I bought one that was lower priced and I got what I paid for. I need a new one asap. I looked at this one. Even though it says it’s for koi ponds, in the reviews I read that it was used for TDS, but you can’t just ask certain questions on Amazon.
Any suggestions and pictures would be greatly appreciated.
