Hey QC brothers and sisters,

We are now testing our caustic tank with an easy caustic titration kit. I am now looking for one that measures total acidity. All I see for total acidity are wine kits. Can I use those? We CIP with 2% acid, which is a blend of Nitric and Phosphoric.

Cheers

Just purchase bulk phenolphthalien and 5N NaOH, do the titration yourself. It will be cheaper and easier to reproduce batch to batch than any dropwise kit. We used to buy the kits from Birko, but for the cost of one chemical refill(50mL) you can buy a liter of each chemical.

Your chemical supplier will normally provide kits for free...
