Ammonia nitrogen mainly comes from the microbial decomposition products of proteins in animals and plants. Due to its toxicity, ammonia nitrogen testing is usually required in aquaculture. Ammonia nitrogen in river water or reservoirs mainly comes from agricultural or civilian pollution. Therefore, ammonia nitrogen measurement is also commonly carried out in lakes, river water, drinking water, boiler inlet water, sewage, and industrial wastewater.

The ideal resolution is generally not lower than 0.1mg/L, usually only 0.5mg/L.

The ammonia nitrogen spectrophotometer has a combination optical system of narrowband interference filter and silicon photodetector, ensuring accurate measurement readings every time;
Hanna's meticulously designed CAL Check ™ The HI96733-11 ammonia nitrogen NIST traceable calibration group is used to verify the performance status of the HI96733 ammonia nitrogen spectrophotometer.
The dedicated colorimetric cup locking design ensures that the colorimetric cup is inserted into the same position in the measuring unit each time to maintain the path length of * for accurate results,

It is simple and convenient to add reagents to the water sample to be tested. The reagents will react with ammonia nitrogen in the water sample to produce a yellow color. Based on the color change after the reaction between the reagents and the water sample, the ammonia nitrogen concentration value can be determined using an ammonia nitrogen spectrophotometer.

Built in timer - ensures that the tested water sample and ammonia nitrogen reagent react according to the internally set standard time. At the end of the timer, the instrument will automatically read the reading, ensuring the consistency of reaction time for multiple batches of measurements.

GLP Function - Record the date of the last user calibration execution

Error messages - warning issues on the display screen, including unlimited, out of range, and under range readings, as well as light source errors;

Automatic shutdown - measurement mode for 10 minutes, or in calibration mode, it will automatically shut down after one hour of inactivity;

Battery status - battery level indicator, 【 ▊▊▊ 】 indicates 100% battery level; 【▊▊】 indicates that the battery level is ≤ 60%; 【 ▊ 】 indicates that the battery level is ≤ 30%; When ≤ 10%, the battery icon flashes, prompting the user to replace the battery in a timely manner.
