AMMONIUM IN WATER
Ammonia is a common byproduct of protein breakdown and is excreted by animals as ammonia, urea or uric acid. Ammonia is also commonly found in fertilizers and is used as a nitrogen source for plant growth. It is effective in cleaning chemicals and can be found in glass and floor cleaners. Ammonia exists in two forms. One is ionized ammonium (NH4+) and the other is gaseous ammonia (NH3). The relationship of which form is present depends on the pH of the solution with ammonium becoming more dominant at pH levels below 8. Since most natural water has a pH of 8 or less, ammonium is the most common form present. For aquatic life, this can be lethal when the pH increases as the ammonium is converted to ammonia, which is more toxic as it can diffuse back into the animals. In surface and ground water, unless there is some contamination, concentrations are very low. In drinking water, ammonia is often added to the water at concentrations less than 0.4 mg/L to increase the effectiveness of chlorine as a disinfectant. Using the Nessler method, the HI 97700 is designed to measure ammonia in the low range at levels from 0 to 3.00 mg/L ammonia-nitrogen. Results can be displayed as either ammonia or ammonium.
MODERN FEATURES
Step-by-Step On-Screen Instructions
Setup, calibration and measurement instructions with step-by-step instructions and on-screen animations.
Simply access Guidance Mode at any stage during setup or measurement using the dedicated HELP key.
AUTOMATIC DATA RECORDING
No need to worry as the photometer will automatically record the last 50 measurements.
Results can be viewed immediately using the Log Recall Menu.
CAL Check FeatureTM Hanna's direct, simple procedure to ensure the photometer is working properly.
Simply insert the cuvettes containing Hanna standards into the meter and follow the instructions.
(HI97700-11)
Light Emitting Diode (LED) lamps provide more light but use less energy and generate less heat.
Narrow band interference filtering results in more accurate measurement results and higher repeatability.
A concave focusing lens reduces errors from imperfections in the cuvette.
High durability
Designed to withstand shock and water, the new IP67 body ensures top performance in any environment. The internal optical system prevents dust, dirt and water from entering. This photometer uses a proprietary positioning system that ensures the cuvettes are placed in the holder in the same position for accurate measurements every time.
Compact design
Designed to fit comfortably in your hand for on-the-go or tabletop use, the LCD display provides quick readings from any angle, day or night. The battery provides over 800 measurements.
The machine has calibration and accuracy testing functions.
CAL Check FeatureTM Hanna's direct, simple procedure to ensure the photometer is working properly.
Simply insert the cuvettes containing Hanna standards into the meter and follow the instructions.
