  • Buffer (2 bags) with a pH value of 4.01 and a pH value of 6.86
  • Tolerance range ± 0.01 pH
  • No color, no contamination of the electrode
  • Prepare the solution in a glass or neutral plastic container
  • Shelf life after reconstitution: 1 month
  • Store in a cool place out of direct sunlight
  • Economical, reusable, 250 ml buffer capacity
  • On the back of the bag there is a table for correcting the buffer value depending on the temperature

Instructions for use:
Pour the contents of the bag in 250 ml of demineralized water (at a temperature of 25 ° C), stir with a plastic spoon and wait for the powder to dissolve completely, then calibrate the meter according to the instructions with a solution with a certain pH value.

The pH meter should be calibrated with the buffer that comes closest to the expected pH of the solutions we normally measure. For example, if we normally measure acidic solutions, the meter should be calibrated with a buffer with a pH of 4.01 if we buy alkaline solutions with a buffer with a higher pH.

Every pH measuring device should be calibrated regularly to ensure measurement accuracy. Meter calibrations should start with acidic solutions and end with alkaline solutions.
