Hanna HI784-25 Marine Ammonia Reagents

Hanna HI784-25 Marine Ammonia Reagents

The Hanna HI784-25 Marine Ammonia Reagents are high-quality, pre-measured chemical packets formulated for use with the HI784 Marine Ammonia Checker HC. Designed specifically for saltwater applications, these reagents allow users to perform fast, reliable, and highly accurate ammonia measurements in reef tanks, aquariums, and marine systems.

The reagent follows the Salicylate Method, in which a chemical reaction between ammonia and the reagent causes a blue-green tint in the sample. The intensity of the color is then analyzed by the HI784 Checker to determine ammonia concentration in ppm (mg/L).

Key Features:

• Specifically for Marine Use: Designed to work accurately with seawater samples.

• Pre-Measured Convenience: Each packet contains the precise amount needed for one test—no preparation required.

• High Accuracy: Delivers results with ±0.05 ppm ±5% of reading at 25°C.

• Reliable Reaction Chemistry: Based on the Salicylate Method, providing clear, consistent color development.

• For Use with HI784 Checker: Fully compatible and optimized for the HI784 Marine Ammonia Checker HC.

How to Use:

1. Fill the cuvette with the prepared saltwater sample.

2. Add the contents of one HI784-25 reagent packet.

3. Mix the solution thoroughly.

4. Insert the cuvette into the HI784 Checker HC.

5. Read the ammonia concentration displayed in ppm (mg/L).
