Product details

application area

G21Ammonia nitrogen rapid water quality analysis analyzerIt can be widely used for water quality testing in research institutes, sewage engineering, water environment testing, petrochemicals, metallurgy and steel, biomedicine, food and dairy industry, wool textile printing and dyeing, electronic machinery, aquaculture, photovoltaics, leather, papermaking, and other fields.

Detection Principle

Ammonia nitrogen rapid water quality analysis analyzerThe determination of ammonia nitrogen is carried out using Nessler's reagent colorimetric method. The water quality detection item is selected, and the imported cold light source emits a light source signal to the sensor. The data is processed by a RAM processor and directly fed back to the sample concentration value, which is displayed in mg/L.

Product Features

The determination of ammonia nitrogen follows the national environmental standard HJ535-2009, and the results are accurate and effective.

Imported solid-state cold light source with stable optical performance, no need for light source preheating, and a light source lifespan of up to 10 years.

Multiple samples can be tested, and continuous detection mode can be activated to achieve higher detection efficiency.

Equipped with Glos water quality intelligent detection system and data averaging calculation dozens of times per second.
Functions such as automatic printing of detection results and guidance of detection mode.
Equipped with complete consumables and reagents, with low prices and minimal usage.
4.3-inch high-definition color screen, flat UI design.
ABS material, high-strength, corrosion-resistant, and high-temperature resistant shell.
