Question
Why is catalog number/order code 25M1A1025-115 used inside sensors as standard solution?
Summary
pH/ORP sensor maintenance details
Answer
The differential pH/ORP sensors use a special concentrated 7 pH solution containing stabilizers and mold inhibitors to prevent contamination. In addition, this solution is 10 times more resistant to changes in pH than the pH 7 calibration buffer. This allows a long working life of the solution over the course several months
