The PC MultiDirect is a contemporary, microprocessor-controlled photometer with ergonomically designed keypad and large-format graphic display. It is equipped with a wide range of pre-programmed methods based on the proven range of Lovibond tablet reagents, liquid reagents, vial tests and powder reagents (VARIO Powder Packs). Users can also store their own methods. The calibration and software-based adjustment options mean that the PC MultiDirect is also suitable for use as a testing instrument. For portable use, the instrument operates with seven standard rechargeable batteries (supplied). These batteries are available all over the world and are easily changed. The integrated intelligent charge controller allows simultaneous operation of the unit and battery charging (using the supplied power pack). The PC MultiDirect also operates without a power pack by using alkaline manganese batteries. The entire instrument, including sample chamber (the most critical component of any photometer) and battery compartment, is waterproof, ensuring that no water can come into contact with the electronic components.
