HI93728-01 Nitrate Test Reagent Kit
The Hanna HI93728-01 reagent kit uses the cadmium reduction method to accurately measure nitrate levels in water from 0.0 to 30.0 mg/L. This 100-test kit is designed for use with Hanna photometers and colorimeters, providing reliable nitrate testing for drinking water compliance, aquaculture monitoring, and agricultural water analysis.
Cadmium Reduction Process
Sample Collection
Collect water sample in clean cuvette or test vial. Sample should be free of large particulates and at room temperature for accurate analysis.
Reagent Addition
Add HI93728-01 reagent to sample. Cadmium metal reduces nitrate to nitrite, which then reacts to form a pink-colored complex proportional to nitrate concentration.
Color Development
Allow reaction time as specified in instructions. The intensity of pink color corresponds directly to nitrate level present in the water sample.
Photometric Reading
Insert prepared sample into compatible Hanna photometer. Device measures absorbance and calculates nitrate concentration in mg/L with lab-grade accuracy.
Compatible Hanna Instruments
The HI93728-01 reagent kit is designed for use with Hanna photometers and colorimeters that support the nitrate cadmium reduction method. Compatible models include the HI83200, HI83300, and other benchtop or portable photometers with nitrate testing capability. Each kit provides 100 tests with a measurement range of 0.0 to 30.0 mg/L, ideal for monitoring drinking water compliance with EPA standards, testing aquarium or aquaculture water quality, and evaluating agricultural irrigation sources. Store reagents in a cool, dry place away from direct sunlight and follow expiration dates for accurate results.
