Dual Beam Technology and Interference Filters photometer with economically designed keypad and large- format graphic display. It is equipped with a wide range of pre-programmed methods based on the proven range of AQUALYTIC® tablet reagents, liquid reagents, tube tests and powder reagents (VARIO Powder Packs). Users can also store The AL450 is a filter photometer using interference filters at ó different wavelengths. The unique design of the optics allows the automatic selection of the required wavelength without any moving parts. This and the dual beam technology utilizing an internal reference channel, guarantees the highest accu- For portable use, the Instrument operates with seven standard rechargeable batteries (supplied). These batteries are availa- ble 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 AL450 also operates without a power pack by using alkali- The entire Instrument, including sample chamber (the most critical component of any photometer) and battery compart- ment.

N.I.S.T. Traceability The instrument has a factory calibration, which is related to in- ternal standards, which are not N.I.S.T traceable. The Instrument may be calibrated by the user In a "user calibration mode" with N.I.S.T traceable standards, (N.I.S.T. = National Institute of Standards and Technology) Test methods are regularly updated to suit market requirements You can find software updates for new methods and additional languages on our website at www.aqualytic.de. With the help of an external mathematical program, the cor- responding polynomial is created from data pairs (concentra- tion/absorption)....
