15x Calibration Powder for pH Meter 4.00 6.86 9.18, Powder, Buffer Solution Set

✔ [Calibration powder for accurate results] The calibration powder is suitable for all pH meters that should be calibrated according to the specified pH sizes. The powder is dissolved in 250 ml of water. ✔ [Correct deviating values] If implausible readings are achieved, your pH meter can be calibrated again using this calibration powder. ✔ [Quick and easy] After the powder has been dissolved with 250 ml in distilled water, a calibration liquid is created, which is ready to use. ✔ [Long shelf life] A special advantage is that the calibration powder has no expiration date and can therefore be used for many years. ✔ [For many buffer solutions] The solutions included in the set (5 sets with buffer solution 4.00, 6.86 and 9.18) are sufficient for a total of five calibrations. This in the 3 step process. Please refer to the pH meter manufacturer's instructions.
