TR-205 Total Chromium and Chromium Ion Analyzer (with printer)

Detection principle:

Add an oxidant to convert trivalent chromium into hexavalent chromium, then add a color developer to react with hexavalent chromium to form a purple red complex. Measure its absorbance using spectrophotometry, and after processing and calculation by a microcomputer system, directly display the total chromium content (mg/L).

Product Features:

1. Developed and designed according to the GB7466-87 "Determination of Total Chromium in Water Quality" standard, the measurement is accurate and effective.
2. Adopting imported high brightness and long-life cold light source, with excellent optical performance and a light source lifespan of up to 100000 hours.
3. Large LCD screen with full Chinese display, direct data reading, simple and time-saving operation.
4. Integrated digestion and colorimetric analysis, no need to replace the tube, simple and fast measurement, and no safety hazards.
5. It can save 80 standard curves and 1800 measured values (date, time, parameters, test data).
6. Memory standard working curve, users can also calibrate the curve as needed.
7. One click factory reset, which can quickly recover in case of curve loss caused by misoperation.
8. It has a curve coverage interference function 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. It has a printing function, which can immediately print the measured values or query historical records for printing.
12. 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.
