CHECKIT Comparator The CHECKIT Comparator is a compact handy colorimeter unit which is suitable for both mobile and static analysis work.
CHECKIT Comparator is a colorimetric rapid test for easy determination of Free Chlorine, Total Chlorine, Chlorine Dioxide or Ozone concentrations that can be used as an indication measurement for our amperometric measuring systems. Naturally, regarding resolution and accuracy, the rapid test does not come close to the Krypton systems, and it cannot replace a fotometric measurement. However, it provides a quick orientation and can therefore prove helpful during installation or routine comparison.
The CHECKIT Comparator comes in a robust plastic casing with all necessary equipment.
PKV 30-DPS Converter for PROFIBUS-DP for max. 32 instruments of the K 100 oder dialog series. Converting of RS 485 to PROFIBUS-DP interface, instrument in a housing for installation on a top hat trail, dimension 105 X 105 x 80 mm (HxBxT), connectioncable inclusive
S-341 data logger The bus data logger S-341 on the base of the RS-485 with Kuntze protocol reads, shows, and stores measuring data of up to 10 Kuntze instruments with up to 8 parameters each.

dialog. Versatile meter and controller...
Large graphical display, trend indication, log book, text menu. Two PID controllers, three analog outputs, and serial interface.

Redundance spells security...

Reliable process control. With the dialog´s double measurement function you will immediately recognise sensor faults.

Ratio spells efficiency...

Surveillance of treatment processes. Monitor the efficiency of your ion exchangers via conductivity reduction using the dialog´s difference measurement function.

Combination spells compensation...

Independence of interferences. For disinfection with Chlorine, the pH value plays an important role. With the dialog you can measure and control Chlorine and pH simultaneously, and automatically compensate the pH influence on the Chlorine measurement.
