Aqua Master Tools pH 7 Calibration Solution - 100 ml

Product detailed description

Aqua Master Tools pH 7 calibration solution is a neutral standard for setting pH metres. It is used with pH pens, combined metres and monitors that calibrate pH at two points.

What it is used for

For most Aqua Master Tools pH metres, pH 7 is one of the two main calibration points. The second point is pH 4 calibration solution. Pour the solution into a clean container and do not return it to the bottle after use.

Two bottles in one calibration

Two-point calibration means that you immerse one electrode in two different solutions one after the other. Therefore, rinse the electrode thoroughly with clean water before and after each use.

Pour only the amount needed for one calibration into a clean container, close the bottle immediately and store it at 15 to 25 °C away from direct sunlight. Pour away the used amount - it must not be returned to the bottle, even if the electrode was in it only for a short time.

Parameters

• Type: pH calibration solution
• Value: pH 7.00
• Volume: 100 ml
• Storage: closed bottle at 15 to 25 °C, away from direct sunlight

If the electrode is visibly dirty, clean it before calibration using Aqua Master Tools Cleaner D.

Frequently asked question

Is pH 7 enough for calibration?

For devices with two-point calibration, use both pH 7 and pH 4. A single-point pH 7 check is a quick reference, not a full two-point calibration.
