80 mV Kit – Comes with Quinhydrone powder and 2 oz. bottle of PH7 solution

A series of Calibration solutions designed specifically for the Myron Ultrapen PT3 and PT4. For maximum accuracy and ease of calibration, the Myron L Company has developed three calibration standard solutions with known dissolved species. We derived the temperature compensation (from 15?C to 30?C) for those solutions, and embedded automatic temperature compensation into the calibration function of your PT3. Note: To verify calibration while in measurement mode, you must manually correct for any variation in temperature. Example: @25?C, ORP2602OZ calibration solution will read 260mV, however @ 20.0?C ORP2602OZ will read 265mV. Purchasing chemicals Can I buy chemicals as a private individual?
