- Recommended for simplifying nitrate measurements in natural waters, drinking waters, soils, fertilizers or other samples with high chloride or carbonate content
- Eliminates chloride and other anion interferences
- No filtering of samples required
- Now two measurements, NH3 and NO3, can be made with one electrode
Includes: One 1 pint (475mL) bottle alkaline reagent (951011), one 1 pint (475mL) bottle reducing reagent (700006), two 1.6 oz. (50mL) bottles of ammonia electrode filling solution (951203), one 1 pint (475mL) bottle of 100ppm nitrate as N standard (930707), one 1 pint (475mL) bottle of 100ppm ammonia as N standard (951207), two reagent delivery systems and Technical Bulletin 115, Nitrate Measurement in Environmental Samples.
