Water quality monitoring - multiparameter probe


The water quality measuring instrument (multiparameter probe) has been developed specifically for the instant determination of ground water quality values in situ. Profiles in observation boreholes or monitoring wells are easily obtained as are quality measurements in lakes, rivers and oceans. The portable and compact design is based upon the proven electric contact meter, with its robust supporting frame and tape drum. The detachable probe is made from high quality stainless steel whilst the standard white printed measuring tape enables precise depth readings to within a centimeter accuracy.

The instrument is operated via an integral key pad and liquid crystal display. The unit responds to water contact with a lamp and tone. At the touch of a button the tone is cancelled and the LCD shifts through the measured value of the quality parameters, any single channel parameter can be locked in for examination in greater detail. The whole operation and other facilities such as off sets or instructions are conveyed to the operator by the display.

On the standard instrument the probe is detachable from the printed tape, enabling easy service or repair. When the probe is reconnected the microprocessor-controlled unit will automatically recognize different sensors and parameters, adjusting for range (conductivity) or zero point automatically.
