Ammonia Standard Solution is required for Ion Selective Electrode (ISE) calibration. Use this solution to get accurate test results for in-lab and field analysis.
Hach Standard Solution (p/n 2354153) is used to conduct Ion Selective Electrode (ISE) verification for laboratory and field analysis. The solution has the concentration in the range of 1000 mg/L ± 20 mg/L NH₃-N. 500 mL is the volume of each bottle. Ammonia Standard Solution is NIST traceable for performance verification. To preserve the shelf life of the solution, it is sealed in an airtight package.
Storage conditions
The temperature range of 10 °C to 25 °C is recommended for the ISE Standard Solution storage. The solution is required to be kept in the place protected from direct sunlight. Ready-to-use Standard Solution has a three-month shelf life after opening.
