threeProduct Features
1. ReferenceRelevant standardsHJ/T399-2007。
2. The instrument is equipped with a high range and a low range. The low range is measured using different wavelengths according to national standards, resulting in more accurate measurements.
3Adopting imported high brightness and long-life cold light source, the light source has a lifespan of up to 100000 hours.The instrument has better stability and more accurate measurements.
4. LEDliquid crystaldisplayIn Chinese,CODDirect data reading, simple operationsecure.
5Dissolve colorimetric integration,After digestion,need notTransfer samples and measure directly,Time saving, Quickly.
6It can save 60 standard curves and 2000 measured values (date, time, parameters, test data).
7The memory standard working curve, and users can also calibrate the curve as needed.
8. Built-in rechargeable lithium battery,And equipped with a portable aluminum box, convenient for outdoor on-site measurement.
9. set uphaveUSBInterface,approveData can be transmitted to a computer, convenient for analysis, comparison, andPermanently stored.
10. There areOne click factory resetfunctionIt can quickly recover when the curve is lost due to misoperation.
11. There areData power-off protection function,Prevent dataaccidentloss.
12. Separate the digestion instrument and the measuring instrument, do not interfere with each other, and reduce measurement errors.
13. DigesterOne click selection of digestion mode, room temperature available-Free setting at 200 ℃.
14. DissolverAdopting intelligent technologyPID temperature control technology, uniform heatingIntelligent temperature control.
15. The digester is equipped withAnti overheating protection system function, achieving heating temperature alarm prompt and constant temperature.open up or clear out by poking or jabbingused forCOD、 The digestion of total phosphorus, total nitrogen and other items.
16. According to customer needs, thermal printers can be selected to print measurement data in real-time for easy recording, analysis, and discussion.
