Hanna HI767-11 Marine Nitrite low range

Hanna HI767-11 Marine Nitrite Low Range Checker HC

The Hanna HI767-11 Marine Nitrite Low Range Checker HC offers a precise, affordable, and user-friendly solution for measuring nitrite levels in marine environments. Bridging the gap between simple test kits and complex laboratory instruments, the HI767 delivers lab-quality results with the ease of digital technology, making it ideal for reef keepers, aquarists, and marine water professionals.

Using a modified EPA Diazotization Method 354.1, this handheld colorimeter provides highly accurate readings by detecting the pink tint formed during the reaction between nitrite and reagent. It is specifically designed for saltwater samples requiring low-range nitrite analysis.

Key Features:

• Low Range Sensitivity: Measures nitrite concentrations from 0 to 999 ppb (as NO₂-N), ideal for marine environments where precision is critical.

• High Accuracy: ±10 ppb ±4% of reading @ 25 °C ensures dependable, repeatable results.

• Simple Operation: One-button design for easy measurement—no complicated calibration or interpretation of color shades.

• Advanced Optics: Uses a fixed-wavelength LED @ 470 nm and a silicon photocell detector for accurate colorimetric analysis.

• Auto Shut-Off: Automatically powers down after 20 minutes of inactivity or 4 minutes after a reading, conserving battery life.

• Portable and Compact: Palm-sized design is ideal for both field and lab testing.
