Characteristics of water quality COD measuring instrument1. The instrument adopts a 4.3 inch color TFT screen, with a user-friendly interface according to the testing needs;2. The instrument supports large-scale storage of data (date, time, parameters, measurement results), as well as USB flash drive storage. The instrument and USB flash drive can be transferred for convenient customer use;3. Data transmission, capable of connecting to a computer and transmitting data to the computer through a USB interface, supporting Bluetooth wireless transmission (optional);4. The instrument supports 200 curves, and the instrument can customize high-precision measurement curves according to the measurement range requirements. The curve also supports customers to establish instrument segmentation curves, and the segmentation coefficient K can vary depending on the measurement concentration, thereby improving measurement accuracy;5. The instrument adopts an ARM9 main control chip, which ensures a smooth operating interface, fast response speed, and a large internal storage capacity of up to 500M of memory;6. The instrument adopts the national standard colorimetric dish colorimetric method;7. The instrument adopts a high-precision filtering system, which improves the stability and measurement accuracy of the instrument compared to the same industry in China;8. Direct reading of concentration, fast and accurate determination of concentration;9. The lifespan of the light source is longer with imported tungsten lamps;10. Curve correction, supporting automatic curve correction and automatic saving;11. Memory curve, 5 manufacturer curves, 195 extension curves, a total of 200;12. Curve customization: customize high-precision curves based on the customer's measurement range to improve the accuracy of analysis and measurement. Support customers in establishing instrument segmentation curves, with segmentation coefficients determined based on concentration.13. Configure high-precision prefabricated liquid reagents for safer, simpler, more accurate, and faster measurements!
