Hanna HI97728C Nitrate Photometer Kit
A nitrate photometer kit for environmental water testing
The HI97728C combines Hanna’s nitrate photometer with a carrying case and CAL Check standards. Its quoted range is 0.0–30.0 mg/L as nitrate nitrogen, NO₃-N. The meter can also display a converted nitrate result through its Chemical Form setting, so record the selected form with the reading.
Choosing the right measurement
The method has important interferences. Hanna lists chloride above 100 mg/L as a negative interference, so the instrument must not be promoted as a seawater nitrate Checker. Keep the reported chemical form with each result, and assess the suitability of strongly coloured or turbid samples before testing.

Reagents and optional accessories
HI93728-01 is the separate 100-test reagent pack; HI93728-03 is the 300-test pack. Check standards and sample reagents perform different jobs.
Care and reliable results
The CAL Check standards validate and calibrate instrument performance; they are not the reagents used to test a water sample. Dedicated nitrate reagent packs are separate. Follow the exact manual’s reaction procedure and room-temperature conditions, and read the reagent safety information before use.
