Analysis method can be endpoint, rate, two-point, single wavelength, dual wavelength, blank reagent, blank sample, and absorbency. Calculating method like single and dual-point calibration is also available. It has a halogen lamp (6V/12W) with long lifespan and wavelength range of 340 to 630nm. There are 7 basic filters: 340, 380, 405, 510, 545, 578, and 630nm and 2 optional filters. The central wavelength has an accuracy of ±3nm. Its resolving power for display is 0.001Abs and 0.0001 Abs for inner calculate. Slope error is ?5% with sway of 0.003A/h. The 10mm 35?L colorimetric tank is made of quartz/stainless steel. It also features temperature control at 25?, 30?, 37?, (±0.1? variable). The sampling volume can be set with recommended volume of 500?L. The chances of cross contamination or repeat is below 1%. The analyzer is computer-controlled with bidirectional communication available. It can store 200 items and 100,000 test results. It is connected to a color LCD that displays reaction curve real-time. As for test reports, there are 3 formats available. It also features RS232 output and connected to an external computer.
