Happy Harvest pH Calibration Fluid 7.0 allows you to keep your pH meter accurate and on top of your growing game.
How to calibrate your pH meter:
Pour a small amount of calibration fluid into a clean and dry container just big enough for the pH pen’s probe side to fit into, an empty bottle cap or small cup works well. Don’t use any metals.
If you can, rinse your pH meter’s probe end off with distilled water before calibrating it. Your pH meter will either have a electronic or manual calibration.
If electronic, submerge the probe in the calibration fluid and press the calibration button, select which pH to calibrate to and press enter, wait for the meter to finish.
If manual calibration, your meter would have come with a screw driver and somewhere on the meter, sometimes in the battery compartment, there is a small screw. As above, submerge your pH meter’s probe in the calibration fluid, and turn the screw slowly so that the reading on the meter matches the pH calibration fluid’s value, 4.0 or 7.0 for example.
Once you’ve calibrated your meter, rinse it clean water and it will be ready to use. Do not throw the used calibration fluid back into the bottle.
