Calibration Solution Meytec pH 4.01 – 60 ml

The pH 4.01 calibration solution in a 60 ml pack is intended for pool operators and service technicians who carry out calibration of pH electrodes repeatedly throughout the season. The larger pack volume reduces the cost per calibration and eliminates the need to frequently order replenishment stock.

The guaranteed value of pH 4.01 (±0.01 at 25 °C) is a standard lower calibration point compatible with all standard pH electrodes and dosing units for pools and hot tubs. The solution is chemically stable and preserves its value throughout the shelf life when stored correctly.

For optimal results, we recommend combining it with the pH 7.00 calibration solution for a two-point calibration that covers the entire operating range of pool pH electrodes.
