Water quality nitrogen analyzer

1. Equipment Introduction

The HD-T3N water quality three nitrogen analyzer is an independently developed product of Shandong Holder Electronic Technology Co., Ltd. It is designed and manufactured in full accordance with relevant standards and is applicable to many testing standards at home and abroad.

This instrument mainly detects the concentration indicators of ammonia nitrogen, nitrate nitrogen and nitrite nitrogen in water quality, and has intelligent data analysis functions. The 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.

2. 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.

3. Functional characteristics

2. 8-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 problem of error in the 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. Multifunctional 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 mobile testing;

13. Built-in teaching demonstration video, users can watch the operation video in the instrument while performing experimental operations, which is easier to get started.

14. The firmware of the later product can be upgraded.
