HI-700044P - Pool Line pH 4.01 buffer solution, 25 x 20ml sachets

The pH 4.01 buffer is one of the most commonly used buffer solutions. It is extremely stable and represents the mid-way point in the acid range of the pH scale - ideal for those requiring an accurate acid reading, particularly those working in swimming pools, hot tubs and spas, and wherever the pH is expected to be acidic.

Buffer solutions should be stored at 25°C, away from direct sunlight for accurate readings.

To correctly maintain your meter/electrode, we highly recommend use of a Hanna cleaning solution, as well as a buffer, for maximum performance every time.

Hanna buffer solutions are prepared, ready-to-use, according to precise formulas and standardised in accordance with the National Institute of Standards and Technology (NIST) to ensure quality and accuracy. All solutions show a batch number, an expiry date, and the correlation table between pH and temperature. A certificate of analysis is available on request.

Benefits of individual packaging

• Ideal for users who do not calibrate frequently
• Ideal for field use due to portability
• Every sachet is as fresh as the day it was packaged
• Light block packaging prevents oxidation from UV light that could alter the buffer value.
