Highlights Interface RS232 Large illuminated display Touch-sensitive film keypad with logical layout Use of round vials and rectangular cells of different sizes without adapter 35 user-specific methods Fast, easy lamp change Update via Internet Description The AL800 is a modern single-beam spectrophotometer with an excellent price/performance ratio that is specifically designed for water testing. The instrument is equipped with a wide range of pre-programmed methods based on the proven range of AQUALYTIC tube tests, tablet reagents, liquid reagents and powder reagents (Vario Powder Packs). The AL800 allows differentiated tests for certain methods. With the Chlorine method, for example, differentiated measurement is possible for free, combined and total chlorine. The user chooses the desired method either from the method list in alphabetical order or by entering a numerical code. If desired additional information like the required vial, the reagent type and the measuring range can be displayed using the functional keys. The date and time are shown in the display by pressing the „clock key“. The AL800 automatically selects the correct wavelength. Zero calibration is performed with the water sample by pressing the ZERO key. A characteristic coloration develops when you add the indicator to the water sample. Press the [Test] key to initiate the measurement (which starts either immediately or after the time required for colour development).
