Profile: Partech (Electronics) Ltd. specializes in offering instruments for water & wastewater industries. The 7300w² monitor is the core to the WaterWatch² product range. The monitor is designed to interface with all the sensors in the WaterWatch² range. The starting specification provides all the connections required for 1 or 2 sensors, and systems can be created by the use of expansion boxes to include multiple sensors. The maximum number of sensors will be limited by the practicalities of most sites. We anticipate 8 being a sensible maximum, although many more can be accommodated. The graphical display has been chosen to provide the best possible contrast, even in bright sunlight. In normal operating mode the display gives a large digit display of the measured parameter(s), the user can also select a trend display giving an indication of site performance over the last week. The MicroMac C is designed to operate in an industrial or treatment works environment with minimal routine intervention, and uses industry standard chemistry methods wherever possible. The robust nature of the MicroMac C with its separate electronic and chemistry compartments the latter including reagent storage provides a reliable on-line analyser.
