Aqua Master Tools pH 7.00

Description

Keep pH meters correctly calibrated at the pH 7.00 reference point

Aqua Master Tools pH 7.00 Calibration Solution is designed for routine calibration of pH meters used with water and nutrient solutions. Its defined reference value allows you to check and adjust your meter before taking measurements. It is therefore a practical maintenance product for pH meters used for growing and comes in four sizes ranging from 20 ml to 5 L.

Defined reference value with NIST traceability

The calibration solution has a reference value of pH 7.00 at 25 °C and is traceable to a NIST standard. As with pH buffer solutions generally, the specified value changes slightly with temperature. For correct calibration, take the temperature of the solution into account and follow the instructions supplied with your meter. Instruments such as the Aqua Master Tools P50 Pro2 use pH 7.00 as one of their calibration points.

Four sizes for different levels of use

The compact 20 ml sachet is convenient when only a small quantity is required. The 100 ml and 500 ml versions provide more solution for regular recalibration, while the 5 L size is intended for correspondingly higher consumption. This lets you select a suitable quantity while continuing to use the same pH 7.00 reference solution.

Clean handling helps protect the reference solution

Pour only the amount required for calibration into a clean container and calibrate the instrument according to its operating instructions. Solution that has already been used or poured out should never be returned to the original container or reused. Bottles should be closed immediately after dispensing. Aqua Master Tools specifies a storage temperature of 15–25 °C.
