Description

Prepare your pH meter for the next measurements

Regular calibration lets you check whether the meter and electrode read known pH values correctly. This Hanna pH 4.01 and 7.01 buffer set is a practical aid for preparing a pH meter to test milk, cheese and other samples, following the procedure for your instrument.

Two reference points in one pack

5 sachets of pH 4.01 buffer and 5 sachets of pH 7.01 buffer. Each contains 20 ml of ready-to-use solution: 10 × 20 ml in total.

A fresh portion instead of a large open bottle

Single-use foil sachets let you open the solution when needed for calibration. This makes work easier to organise and reduces repeated use of the same opened container.

Specifications and use

Buffer value accuracy: ±0.01 pH at 25°C. Select calibration points and follow the procedure in your meter instructions. The sachets are single-use; follow the packaging information.
