Product Features
High quality LED light source system
Compared with traditional tungsten lamps and other light sources, LED light sources have higher performance and luminous efficiency, and can provide the best and stable light source with less energy. LEDs can ignore the heat generated by themselves, as higher heat can affect the stability of electronic products.
High quality optical filter
8 nm narrowband interference filter, accurate to ± 1 nm, with a 25% increase in absorbance. The improved optical filter ensures higher wavelength accuracy and allows for brighter, stronger signals to be received, higher measurement stability, and less wavelength error, ensuring measurement accuracy and precision.
Reference detector
The internal reference system can compensate for any drift caused by battery voltage fluctuations or environmental temperature changes. By automatically adjusting the voltage of the LED, it achieves consistent and stable light source output, enabling fast and stable readings between blank (zero) measurements and sample measurements.
Stable and efficient light source setting
High quality concave focusing lenses can collect all the light transmitted through the glass cuvette, reducing errors caused by defects and scratches in the glass cuvette, and minimizing errors and reading deviations caused by defects in the glass cuvette.
CAL Check ™ function
Carefully designed CAL Check ™ Function, allowing the use of NIST traceable standards for instrument performance validation and calibration; CAL Check ™ NIST curve calibration group is used to simulate specific absorbance values for each wavelength to verify the accuracy of subsequent readings. CAL Check ™ The CAL check screen guides the user through the verification process and user calibration step by step.
