Applications   : water treatment plant, sewage treatment plant, industrial effluents, ground water monitoring, food processing, beveragesm swimming pool, cooling water, etc..

  • Latest German technology, most powerful monitor, micro-processor based.

  • Single monitor can measure up to  8 parameters ( 5 electronic input modules + 3 external analogue input ). Including pH, conductivity, ORP (redox), dissolved oxygen, turbidity (NTU), residual chlorine, carbon dioxide, ozone, temperature, flow, level and pressure.

  • 3 models available : basic modle KM-200. KM-200D has built in data-logger, store up to 7200 data,approx. one year storage. KM-200R has built in PID (Pulse Width Modulation) control.

  • Backlight LED, alphanumeric display, indicates 4 parameters on page 1 simultaneously, shifts to page 2 for other  4 parameters after 10 seconds.

  • 5 ports for external electronic modules, able to measure  5 different parameters or identical parameters.

  • 3  nos. 0 / 4 or 20 mA or 0 to 5 / 10 V input, for external probes such as flowmeter, level sensors, pressure sensors or turbidity probe.  

  • 4 nos. programmable alarm relays, optional max.  8 relays (KM-200R has 2 relays only).

  • Automatic calibration and diagnostic.

  • Automatic Buffer Recognition.

  • Dialogue Prompt Manual, ease of programming.

  • Double security code protects program settings.

  • Optional KMremote software for data verifying, correcting and storage. Time period, time sequence, number of parameters and scaling can be change on PC. Display graphs on historic values.

  • Built in real time clock.

  • ISO 9001 certification.
