Myron L Nitrate Standard Solutions and Ionic Strength Adjusters external power supply making it the electrode forNitrate standards and ionic strength adjuster (ISA) solutions for the Myron L Ultrapen PT6 and UltrapenX2 PTBT6 nitrate pens. The standards cover four decades of concentration so you can calibrate close to the level you actually measure; the ISA solutions condition the sample so ionic strength differences between standard and sample don't skew the reading.
