COMMON FEATURES

High quality silicon photometric diode detector and 1200 lines/mm diffraction grating ensure the high quality accuracy and precision.

Backlit LCD display for an easy readout.

Automatic 0A and 100%T. Easy switching of transmittance, absorbance and concentration modes, just by pressing one key.

Direct concentration read-out and concentration factor setting function.

Large sample compartment, which can accommodate 5mm to 100mm path length cuvettes with optional holders.

Easy to change the halogen lamp or deuterium lamp by the user himself.
