Awhile ago I ordered some replacement solutions from Tftestkits and one in particular has me puzzled. It’s the R-0012 for the CH. With the original solution that came with my TF-100 I was getting a reading of around 525. Now when using the new solution it’s coming in around 800. Any thoughts would be helpful
I’m using the instructions that came with the TF-100 kit which states using a 10ml sample
thanks
