HI749 Hexavalent Chromium LR Colorimeter is a handheld Colorimeter designed for measuring chromium concentration in a specific range. It has a compact appearance, is easy to use and has high accuracy.
Compared with traditional tungsten lamps and other light sources, LED light sources have better performance and higher luminous efficiency. They can use less energy to provide a stable light source. LEDs can ignore the heat they generate because higher heat will affect electronic products. stability.
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.
