Portable Water Quality Tester for Water Testing Lab
The portable water quality tester is based on the principle of characteristic absorption spectrum and the law of light absorption (Lambert-Beer law) of molecular substances to quantitatively analyze unknown concentration samples compared with known concentration standard substances. The instrument consists of an OLED screen, LED light source, colorimetric cell, photoelectric sensor, microprocessor, and auxiliary components. The portable water quality tester adopts high brightness quasi-parallel LED cold light source and advanced optical structure design to provide excellent optical performance and detection results. With a user-friendly interface, simple measurement method, and clear OLED screen display, it is easy to use for both professionals and non-professionals. It is a powerful assistant for scientific research, data analysis, and water quality testing, widely used in research institutes, tap water, hospital sewage, swimming pool water, domestic sewage, aquaculture water, environmental monitoring, petrochemicals, papermaking, pharmaceuticals, printing and dyeing, textiles, leather, brewing, electronics, municipal engineering, and colleges and universities. By simple button operation, multiple indicators of the sample content can be measured, and it can be flexibly customized.
Features
The instrument is fully made of plastic with a streamlined design and a specially treated surface that is oxidation-resistant, acid and alkali-resistant, and core component sealed and waterproof.
The instrument default to be equipped with a 10mL colorimetric tube, which is convenient and fast to operate.
Multi-parameter detection is supported. The instrument can support 420nm, 470nm, 520nm and 620nm wavelengths and can detect various parameters.
With the new optical path structure, the instrument has excellent optical performance and extremely high measurement accuracy and stability.
The instrument adopts a quasi-parallel cold light source, which has the advantages of wide transmission area, energy saving, environmental protection, long service life, and fast response speed.
The test results can be manually saved, saving storage space.
It is equipped with a built-in 2500mAh lithium battery, which can also be charged by connecting a data cable to the power supply.
The instrument can store up to 5000 test results.
It has 5 buttons, an acrylic protective panel, and an ultra-long service life.
The waterproof interface design is compatible with Android phone data cables.
When connected to a computer, the disk is named "M900".
