Review on ๐ก๏ธ Sunmallow Temperature Range Meters by Kev Mills
Not working - NOT CALIBRATED
I followed the instructions as per the attached procedure and I got an "ERR" error message for every PH solution I put it in. The pack contained 2 of each of the instant fixes and ended up using both 6.86 and 4.01. Well maybe this product works great, it's just that the one I received was defective. He gets a star for the trouble I went through.
