TR-108B portable COD analyzer

Detection Principle:

The TR-108B portable COD analyzer from Tongao brand uses a closed digestion tube for closed digestion. In a strong acidic solution, a special oxidant containing a certain amount of potassium dichromate is used to digest the water sample at a constant temperature of 165 ℃ under the action of a catalyst, so that the reducing substances in the water are oxidized. The total absorbance of unreduced Cr6+and reduced Cr3+or the absorbance of reduced Cr3+are measured at different wavelengths.

Product Features:

1. Using EPA approved methods that comply with HJ/T399-2007 standards, the measurement is accurate and effective.
2. Adopting imported high brightness and long-life cold light source with excellent optical performance, the light source has a lifespan of up to 100000 hours.
3. Large LCD screen with full Chinese display, direct data reading, simple and time-saving operation.
4. Dissolve colorimetric integrated, no need to replace tube, simple and fast measurement, no safety hazards.
5. It can save 60 standard curves and 2000 measured values (date, time, parameters, test data).
6. The memory standard working curve, and users can also calibrate the curve as needed.
7. One click factory reset allows for quick recovery in case of curve loss due to misoperation.
8. It has the function of curve coverage interference to prevent accidental operation of covering curves.
9. It has data storage function and data power-off protection function, making it convenient to query historical measurement data and prevent data loss.
10. Equipped with a USB interface, data can be transferred to the computer for permanent storage.
11. Optional printing function, which can print the measured values immediately or query historical records for printing.
12. Built in super large rechargeable battery, with ultra long standby time of up to 168 hours.
13. The digestion instrument adopts intelligent PID temperature control technology and a dual anti overheating protection system, ensuring safe and uniform heating with fast speed. Used for the digestion of COD, total phosphorus, total nitrogen and other projects.
