Myron L pH Buffer Solution — pH 4, pH 7 and pH 10

Myron L pH buffer solutions are color-coded, NIST-traceable buffers for calibrating any Myron L pH sensor. Single-point calibration at pH 7 covers most routine work; add pH 4 or pH 10 for two- and three-point calibration when your samples sit toward either end of the scale. Application Calibrate the pH channel on Ultrameter II 6P, Ultrameter III 9P, PoolPro, TechPro II TPH1, Ultrapen PT2 and UltrapenX2 PTBT2. Bracket the buffers around your expected sample pH for the tightest accuracy — pH 7 and pH 4 for acidic process water, pH 7 and pH 10 for alkaline systems and cooling water. Values and sizes pH 4, pH 7 and pH 10 in 2 oz sample bottles, quarts and gallons. The 2 oz bottles suit single field calibrations; quarts and gallons are economical for shop use and route work. Store the pH sensor in pH/ORP Sensor Storage Solution between uses — never in buffer or in dry air.
