COD tester

Equipment Introduction:

The intelligent COD detector is designed and manufactured according to the "Rapid Digestion Spectrophotometry (HJ/T 399-2007)", which mainly detects the COD content in water quality; this instrument has both intelligent data analysis functions, charts, lists display data, and the analysis is clear at a glance; high-definition color LCD touch screen, Android intelligent operating system, Chinese display interface, Chinese and English keyboards, humanized operation, and easier to use.

Wide application:

It can be widely used in the detection of wastewater in various industries (industrial wastewater, urban sewage, domestic sewage and surface water in rivers and lakes), which can meet the various needs of different users. It can be used in industrial wastewater and various domestic sewage monitoring applications such as chemical, petroleum, coking, papermaking, metallurgy, brewing, and medicine.

Functional features:

1. Adopting the new Android 7.1.1 intelligent operating system, humanized Chinese operating interface, faster operation speed and stronger stability.

2. 10.1-inch LCD touch screen display, humanized Chinese operating interface, intuitive and simple reading.

3. The precision colorimetric cell design and consistent light source can solve the error problem of test results caused by light source error, and the test results are more accurate.

4. The light source adopts imported ultra-bright light-emitting diodes, and the brightness of the light source can be automatically adjusted and calibrated.

5. Supports colorimetric methods such as 10mm, 30mm, 50mm dish colorimetry and φ16mm tube colorimetry, with multiple choices to ensure the accuracy of measurement;

6. It has wireless communication function, supports WIFI, RJ45, mobile phone hotspot network transmission, and the test data can also be exported through a USB flash drive;

7.Multi-function sample management, samples can be named in Chinese and English, which is convenient for sample recording and data storage;

8. The instrument can permanently store 8 million sets of data. To facilitate the search of large amounts of data, it can be retrieved by time and analyzed at will;

9. Supports HDMI output, which is convenient for user training, explanation, and large-screen display.

10. The instrument has a regulatory cloud platform, and data can be uploaded through the local area network and the Internet, and can also be connected and uploaded to the platform of the environmental regulatory department.

11. Built-in thermal line printer, the content on the print paper can be freely selected (including QR code printing);

12. AC 220V, optional 6ah large-capacity rechargeable lithium battery, convenient for outdoor flow testing;

13. Later product firmware can be upgraded.
