Product overview Designed as the reagents for the HI782 Marine Nitrate High Range Checker HC, the HI782-25 reagents deliver a dependable, colorimetric testing experience for saltwater samples

Manufactured with care to high-purity standards, these packets arrive pre-measured for quick, repeatable tests without sacrificing accuracy

In practice, the chemistry behind the HI782-25 uses a zinc reduction reaction that yields a pink tint in your sample

The intensity of the color corresponds to nitrate levels, and your HI782 reader translates that into a readable ppm NO3- value

This setup is intended for saltwater contexts with expected nitrate ranges from 0

0 to 75

0 ppm

What makes HI782-25 unique These reagents are built for ease of use and reliable results

Each packet is clearly labeled with a lot number and expiration date, enabling batch traceability across testing sessions and time

Pre-measured, easy-to-use reagent packets that speed testing High-purity chemicals for cleaner color development Packets labeled with lot numbers and expiration dates for traceability How the color develops Add the HI782-25 reagent to your sample and watch for a pink tint that scales with nitrate concentration

The color is interpreted by the HI782 system and shown as ppm NO3-, helping you monitor marine conditions without guesswork

Designed for marine water ranges Optimized for saltwater testing, these reagents support a measurement range from 0

0 to 75

0 ppm

They are intended to work with the HI782 Marine Nitrate High Range Checker HC to deliver consistent colorimetric readings across multiple tests

-world use and benefits For reef and saltwater hobbyists, quick, color-based nitrate checks practical data points to guide feeding, maintenance, and water-change decisions

While results don’t specific tank outcomes, they provide actionable insight into nutrient trends and water quality

Pre-measured reagents reduce setup time for each test Traceable batch information supports ongoing tank management Simple colorimetric readings align with a clear ppm NO3- scale Usage at a glance Keep testing simple with these steps: Open a HI782-25 packet and add to the sample Mix as directed until the pink color develops to the HI782 scale and record the nitrate reading in ppm NO3- Quality and handling These reagents are manufactured for traceability and stored with clear labeling

Store in a cool, dry place and check the expiration date before use

Use within the window to maintain consistency across tests

FAQ Q: What is included in the HI782-25 Marine Nitrate High Range Reagents kit
