• HI782 Marine Nitrate High Range Colorimeter is specifically designed for the rapid and accurate determination of high-level nitrate in seawater aquariums and marine applications. With a digital reading, there is no more struggling to visually determine color.

• Measuring range up to 75.0 ppm

• Less complicated laboratory-grade accuracy - only 1 reagent required

• Simple and intuitive digital operation

• Compact and precise, whether at home, at work, or on the go

• *  Products classified as dangerous goods can only be shipped by ground transport.

• Nitrate is the final step in the nitrogen cycle. Excess nitrate in seawater aquariums promotes the growth of algae and undesirable organisms such as dinoflagellates. HI782 is a simple, accurate, and cost-effective method for measuring nitrate (as NO3-) from 0.0 to 75.0 ppm in seawater aquariums.

• The HI782 Nitrate Checker HC uses the zinc reduction method to colorimetrically measure nitrate concentration. HI782 provides fast, accurate results in four simple steps:

Features at a glance:

• For use with saltwater samples.

• More accurate than chemical test reagent kits.

• Dedicated to a single parameter.

• Small size and easy to use.

• Error-free digital reading.

• Ideal for aquarium and marine biology applications.

• HI782 High Range Nitrate Checker vs. HI781 Low Range Nitrate Checker

• HI782 is designed to quickly and easily measure nitrate levels for aquarists with above-average nutrient levels. This includes saltwater aquariums with fish only, or corals that can tolerate nitrate levels of 30 ppm or higher.

• Extremely low nitrate levels are critical for many saltwater reef aquariums, as nitrate can cause damage or even death to certain delicate corals and invertebrates. Therefore, HI781 offers unparalleled accuracy in measuring extremely low nitrate levels (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends the HI97728 Nitrate Portable Photometer.
