Portable COD and ammonia nitrogen detector

Product Introduction:

The HM-B02 portable COD ammonia nitrogen detector adopts a high-strength PVC engineering plastic suitcase design and an integrated digestion and detection design. The digestion module has a dual temperature zone function, and the detection part also has 360° rotating colorimetric tube detection and colorimetric dish detection. It has an Android smart operating system, an 8-inch high-definition LCD touch screen, fiber optic detection technology, imported light source, and a built-in large-capacity lithium battery. The portable multi-parameter water quality detector has the characteristics of stable performance, accurate measurement, wide measurement range, powerful functions, and simple operation.

Widely used:

It is suitable for the detection of various water pollutants in domestic sewage, industrial wastewater, groundwater, and surface water; it is used in water quality testing laboratories, municipalities, sewage treatment plants, environmental monitoring stations, and educational and scientific research colleges and universities, power plants, disease control centers, papermaking and electroplating, aquaculture, biopharmaceuticals, petrochemicals, coal, metallurgy, textiles, food and other industries.

Functional features:

1. Using Android smart system version 7.1.1, a smoother interactive experience, faster operation speed, and stronger stability.

2. Dual colorimetric detection system, supporting both prefabricated test tube colorimetry and colorimetric dish colorimetry;

3. The colorimetric tube detection part adopts a 360° precision rotating device to effectively ensure accuracy and improve stability by 10 times.

4. Built-in dual-temperature zone 8-hole digester, with independent control of the left and right temperature zones, which can quickly digest COD, total phosphorus, total nitrogen, etc.

5. Portable integrated detection equipment, built-in large-capacity lithium battery, can realize outdoor water sample digestion and determination in one machine.

6. Built-in thermal printer, supports automatic and batch printing, can flexibly select and edit print content, and supports QR code printing.

7. The instrument has WIFi wireless, 4G remote transmission and RJ45 wired networking functions to upload data;

8. Equipped with Hengmei Data Cloud Platform, it can receive the detection data of the instrument, which is applied to online data storage and long-term and short-term dynamic analysis;

9. Users can build their own standard curves and provide custom calibration of coefficient curves and sample curves.

10. The instrument has built-in teaching demonstration videos, and users can operate experiments while watching videos, which is easier to get started.

11. Detection and digestion can be performed simultaneously, greatly improving efficiency.

12. Detection items can be customized according to user requirements.

13. Equipped with factory-prepared reagent consumables, there is no need to repeatedly pipette and prepare concentrated sulfuric acid. You only need to add water samples into the test tube to perform the test.

14. Built-in humanized pinning function, which can pin the commonly measured indicators to the top. After pinning, it will be displayed at the top of the project list, without the tedious search every time;
