Grating Monochromator : uses 12000line grating which ensures high resolution, low stray light and parameters accuracy. Standard Curve: can set up various standard curves according to customers solution and find the concentration of unknown solution. Data output: equipped with USB port to connect with a PC to edit data through specific software . Data can also be printed through a parallel port connected to a micro printer. Compact design easy to carry. Auto setting wavelength., LCD Display Large sample compartment, it can accommodate 5-100mm path length cuvette with optional holders Display Mode: Can display absorption, transmittance, concentration and coefficient directly by different mode switching.
