Good proudct
I would ignore the 2 star review as the reviewer is obviously ignorant about the difference between Ph and TDS measurement. I have a Hanna meter use this reference solution. I use this solution and a GH reference TDS solution. Both are "accurate" relative to my meter.

Champ ph tester
Was listed an an item needed for ph tester. Never used one like this before but found out later that it isn't used for the champ. Thought I damaged tester when I accidently dropped it in a bucket of water but quick retrival and drying and it is working again a week later.

A blunder in units! NOT "1413 microsecond/cm"
This solution is for calibrating conductivity meters, essential if you are interested in accuracy.This is an Amazon blunder in the description. The product is fine and may be presumed very accurate.The correct units of conductivity are microS/cm, for micro-Siemens/cm.Or, more conveniently, mS/cm; 1.413 milliSiemens/cm.
