Compared with light sources such as traditional tungsten lamps, LED light sources have better performance and higher luminous efficiency. They can use less energy to provide the best and stable light source. LEDs can ignore the heat they generate because higher heat will Affect the stability of electronic products.
HANNA's carefully designed CAL CheckTM function allows performance verification and calibration of the instrument using NIST traceable standards; CAL CheckTM NIST curve calibration set is used to simulate specific absorbance values ââat each wavelength to verify the accuracy of subsequent readings.
