• HI4001-03 is a 1000 mg/L (ppm) ammonia standard solution (as NH3-N) for calibrating ammonia gas sensing combination ion-selective electrodes (ISE). Hanna ISE standard solutions are manufactured using high-purity chemicals and bottled in our own state-of-the-art facilities.

• When performing measurement techniques such as direct measurement and incremental methods, the ISE requires calibration to obtain accurate readings. A maximum of two calibration points is recommended to improve accuracy. Volumetric glassware can be used to dilute the standard solution to achieve the expected concentration of the sample to be measured. ISE calibration standards and sample solutions should always have the same ionic strength; before measurement, the exact volume of ionic strength adjuster (ISA) must be added to all standards and samples.
