Measury PH Calibration Solution 4.00 & 6.86 PH Buffer Solution Fluid - 250ml each – Liquid

• Calibrate any brand's pH meter with these solutions, as long as the stated pH values align.
• The buffers do differ only ± 0.015 pH (at the most) from the stated pH value.
• Choose the set 4.00 & 6.86 if you measure at the low end of the pH scale most of the time (<7). If you plan to measure pH values above 7, the kit 6.86 and 9.18 is your best bet.
• Different to pH buffer powders, there is no need to mix anything with distilled water.
• 250 ml last you a long time since only a small sip of the solution is required to calibrate your device.

The Measury calibration solutions are ready-mixed solutions for the calibration of pH instruments. No further accessories such as distilled water are required, as is the case with calibration powders.Dip the measuring electrode of the pH meter into the calibration liquid and calibrate the meter according to the manufacturer's specifications.Choosing the right solutions:Many commercially available pH meters are calibrated with a two-point calibration.This means that either solutions 4.00 and 6.86 or solutions 6.86 and 9.18 are used.The rule of thumb here is: If you usually measure a pH value in the lower part of the scale which is at or below 7.00 pH, select the solutions 4.00 and 6.86.On the other hand, measure mostly in higher pH ranges, above 7.00 pH, select solutions 6.86 and 9.18.Scope of delivery:1x 250ml Calibration solution 4.001x 250ml calibration solution 6.86
