Hanna Instruments ' HI784 Ammonia Checker Mini Photometer is specially designed to quickly and accurately determine ammonia levels in saltwater aquariums and marine applications . With a digital readout, you won't have to struggle to determine colors visually.
Ammonia reagents for Hanna Instrument HI784 photometer - Allows you to perform around 25 tests.
To determine the amount of ammonia NH3, multiply the value of total free ammonia (NH3/NH4+) displayed by the photometer by the percentage of ammonia indicated in the table below.
Example: pH 8.0, temperature: 24°C, NH3 / NH4+ 1.00 mg/L (ppm)
Concentration of toxic ammonia: 1.00 mg/L (ppm) x (5.0 ÷ 100)= 0.05 mg/L (ppm)
pH | 21°C | 24°C | 26°C | 29°C |
7.6 | 1.7 | 2.1 | 2.4 | 2.9 |
7.8 | 2.6 | 3.2 | 3.7 | 4.5 |
8.0 | 4.1 | 5.0 | 5.8 | 7.0 |
8.2 | 6.3 | 7.7 | 8.8 | 11 |
8.4 | 9.7 | 12 | 13 | 16 |
8.6 | 15 | 17 | 20 | 23 |
8.8 | 21 | 25 | 28 | 32 |
HI784 comes with 2 measuring cuvettes and their caps, reagents for 10 ammonia tests, 1 plastic filling pipette and the battery.
Specifications | HI783 |
Range | 0.10 to 2.50 mg/L (ppm) in NH3 |
Resolution | 0.01mg/L (ppm) |
Accuracy (at 25°C) | ±0.05 mg/L (ppm) ±5% of reading |
Method | Adaptation of the salicylate method. The reaction between ammonia and ammonium and the reagent causes a blue-green coloration of the sample |
Light source | 610nm LEDs |
Light detector | Silicon photocell |
Environment | The prepared sample cuvette (sample plus reagents) must be between 18 and 28°C* |
