Multitracker is a portable instrument for measuring parameters in Water or Wastewater Treatment Plants as well as other industries. Sensors are available for measuring sludge blanket, suspended solids and dissolved oxygen. Cable lengths of 13’, 26’ (standard) or 39’ (4,8,12 m) connect easily to the controller with an M12 plug connector. The Multitracker built-in data logger will store up to 250 samples and 50 fields. The same plug-in sensor connector can be used for the (optional) USB cable for downloading of data. The logged data can now be transferred to a computer and be handled with “Cerlic Tracker Talk” or MS Excel. Two different alarm levels can be set for min/max values on most units with vibration or acoustic signal at set points. Battery life is approximately 1-2 years with normal usage. MultiTracker is supplied in 2 or (optional) 5 sensor pvc case.
