Detection principle:
The TR-105 hexavalent chromium analyzer is designed and developed based on GB7467-87 "Determination of hexavalent chromium in water quality - Diphenylcarbazide spectrophotometric method". The color reagent reacts directly with hexavalent chromium to form a purple red complex, and its absorbance is measured by spectrophotometry. After processing and calculation by a microcomputer chip, the hexavalent chromium content (mg/L) is directly displayed.
Product Features:
1. Adopting imported high brightness and long-life cold light source, with excellent optical performance and a light source lifespan of up to 100000 hours.
2. Large LCD screen with full Chinese display, direct data reading, simple and time-saving operation.
3. Supporting finished reagents, simple and fast determination, without any safety hazards.
4. Can save 80 standard curves and 1800 measured values (date, time, parameters, test data).
5. The memory standard working curve, and users can also calibrate the curve as needed.
6. One click factory reset allows for quick recovery in case of curve loss due to misoperation.
7. It has the function of curve coverage interference to prevent accidental operation of covering curves.
8. It has data storage function and data power-off protection function, making it convenient to query historical measurement data and prevent data loss.
9. Equipped with a USB interface, data can be transferred to the computer for permanent storage.
10. It has a printing function and can print the measured values immediately or query the historical records for printing.
