  • Description

    WTW - photoLab® S12 Filter photometer for comprehensive routine analysis in water, galvanics in universities, service and industrial labs
    Maximum comfort at minimal costs! The photoLab® S12 filter photometer with 12 wavelengths combines lab precision with maximum speed up to economic trace analysis. Place cuvette, read result, done! Optional photoLab® S12-A with recheargable batteries for onsite measurements.

    • Barcode and cuvette recognition for round and rectangular cuvettes
    • Approx. 180 programs including trace analysis and color
    •AQA/IQC multi-level
    •User-defined methods

    photoLab® S12 with reference beam optics has 12 wavelengths for test kits in 16 mm round and rectangular cuvettes. It is easy to use and maintenance-free. The unique barcode system is supporting both 16 mm cell tests and the more economic reagent tests using 10, 20 and 50 mm cuvettes. The automatic cuvette recognitions allows the unique automatic measurement range switch.

    Thus, especially in drinking water analytics, the lowest concentration ranges can be detected. In addition to the almost 200 programmed methods, 100 user-dfined methods can be programmed and kinetic measurements are possible. This allows for a comprehensive routine operation in wastewater and drinking water, food industry as well as in service and teaching labs.

    The device is very efficient and economic for:
    • Routine determinations for a large number of samples
    • Measurement of lowest concentrations
    • Special tasks with user-defined methods

pHotoLab® S6 and S12 - Methods Update - Version 39 / 41

Update of the method data for WTW Photometers photoLab® S 6, S 12 and Spektral.

Download and installation notes:

For updating the photometers via the incorporated RS 232 interface the following accessories and programmes are required:

  • PC (Win95 or higher)
    Photometer photoLab® S 6, photoLab® S 12 or photoLab® Spektral
  • PC cable AK Labor, WTW Order No. 902 758
  • Program file "UpdateMethodData.exe"
  • 6 Method Data files " pls6md.XXX", "pls12md.XXX", "plspekmd.XXX", .....
  • File "Readme.txt"

Update Procedure:

  • Connect the serial interfaces of PC and photometer using the cable AK Labor.
  • Switch on the PC and photometer.
  • Copy all files (program file and six method data files) into a subdirectory or onto a floppy disk.
  • Start the program file UpdateMethodData.exe from this subdirectory/floppy disk.
  • Now all you have to do is to follow the instructions prompted by the program. The program automatically identifies the connected photometer and is self-explanatory in its function.
  • After approval for the update has been granted, all methods are loaded into the photometer, overwriting the old ones in the process (User-defined methods are also deleted and have to be programmed again).
  • The overall method update lasts approximately 3 minutes.

Update of instrument software for WTW filter photometers (devices with serial numbers starting with 1423xxxx).

Version history – innovations

Important Bugfixing – for some instruments, the following error may occur:

-Starting the instrument, the message “Remove cell” appears even if no cell is in the meter
-Instrument start up is frozen
-With the update version V4.03, this is fixed, updates can be performed as usual
