Bluelab pH 7 calibration solution

Product detailed description

Neutral point where every pH calibration begins

The Bluelab pH 7.0 solution is the neutral reference point for two-point calibration – the point from which the accuracy of the entire measurement depends. Together with the acidic pH 4.0 solution, it sets the Bluelab pH metre or pen to display reliably throughout the cultivation period. Regular calibration with fresh solution is the simplest way to maintain measurements you can trust.

Compatibility

The solution is intended for all Bluelab pH measuring devices – pH pens, pH metres, and control units with pH probes. The neutral pH 7.0 point is combined during calibration with the acidic point pH 4.0. Suitable devices can be found in the pH metres category.

Frequently asked questions

Which solution to start calibration with?

Calibration usually begins with the neutral pH 7.0 point and then continues with the acidic pH 4.0 point. The exact procedure can be found in your Bluelab device manual. Both solutions belong together – without the acidic pH 4.0 point, calibration is incomplete and measurements may be unreliable.
