Permanganate Index COD Tester

1. Equipment Introduction

HD-TCMn type permanganate index COD tester (CODMn) is a self-developed product of Shandong Holder Electronic Technology Co., Ltd. It is designed and manufactured according to the national standard method "GB/T 11892-1989 Determination of permanganate index of water quality", and is applicable to many domestic and foreign testing standards.

This instrument uses the manganese method to determine the COD index in water, also known as CODMn or permanganate index. It has intelligent data analysis function, charts and lists display data, and the analysis is clear at a glance; high-definition color LCD touch screen, Android smart operating system, Chinese display interface, Chinese and English keyboards, humanized operation, and easier to use.

It is widely used in the determination of low-content COD in surface water, tap water, etc.

2. Features

2. 8-inch LCD touch screen display, humanized Chinese operating interface, intuitive and simple reading.

3. The precision colorimetric cell design is adopted, and the light source is consistent, which can solve the problem of error in the test results caused by the error of the light source, 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. In order 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 is equipped with 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. Built-in teaching demonstration video, users can watch the operation video in the instrument while performing experimental operations, which is easier to use.

14. Later product firmware can be upgraded.
