The large LCD has new prompts, large fonts, and impressive graphics to minimize the time you have to wait to get results. The soft keypad also has descriptions that will guide you through different programs. From basic concentration measurement to complex quantitative calibration curves, UVmini-1240 has it all. Some of its functions include the factor method for inputting simple constants, one-point calibration curve with a single standard sample as well as a point through the origin, a multi-point calibration curve that requires different standards. The standards are 1st, 2nd, and 3rd order filling of polynomial for calibration. Furthermore, it can do two or three wavelength quantitative analysis for the measurement of thick samples or for the measurement of another component that can be identified.
