Hanna Marine Ammonia Checker HI784

The HI784 Marine Ammonia Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of ammonia colorimetrically. The HI784 is designed specifically to measure ammonia levels in a saltwater aquarium. The 0.00 to 2.50 ppm range is ideal for coral/fish or fish-only aquarium maintenance.

• Ideal for aquariums and marine biology

• Easier to use and more accurate than chemical test kits

• Small size, big convenience

Primary Applications: Marine, Saltwater Aquariums, Aquaculture

Ammonia is a by-product of the Nitrogen cycle. Ammonia is normally removed by nitrifying bacteria, but ammonia levels can rise if there is an imbalance in the tank water chemistry. Excessive ammonia in a marine aquarium increases the risk of inhabitant illness or death.

Range: 0.00 to 2.50 ppm (mg/L) NH3

Resolution: 0.01 ppm (mg/L)

Accuracy: ±0.05 ppm ±5% of reading @ 25 °C (77 °F)

Light Source: Light Emitting Diode @ 610 nm

Light Detector: Silicon photocell

Method: Adaptation of the Salicylate Method. The reaction between Ammonia and Ammonium and the reagent causes a blue-green tint in the sample.

Environment: 0 to 50°C; max. 95% RH non-condensing Prepared sample cuvette (sample plus reagents) must be 18 to 29°C 

Battery Type: 1.5V AAA Alkaline

Auto Shut-Off: After 10 minutes of non-use
