pH Solution

A must have in every grower’s toolbox! Bluelab Calibration Solution is used to ensure that your testing equipmentย is working properly and givingย accurate readings. All buffers are NIST certified andย referenced to high laboratory standards.

Bluelab pH meters are calibrated to pH 7.0 first then to pH 4.0. The company’sย conductivity/ TDS instrumentsย are pre-set at theย factory and do NOTย need calibrating.

Available size: 500 mLย Bottles

Grower’s Tip:
To prevent cross contamination, pour the necessaryย amount of bufferย into a small container and calibrate from here. Discard when finished — do NOT reuse.
