Buffers for calibration giving fast, accurate pH results in high purity and low ionic strength waters. Recommended for samples such as well water, rain water, distilled/deionized water, boiler feed water, and process water.

• Increases measurement accuracy
• Reduces electrode drift
• Eliminates contamination of sample
• For best results, a high quality pH electrode is recommended

pHISA™Adjustor additive is designed to increase sample ionic strength without changing the pH of the sample.
