LAQUA 300 Sensor Heads
Your LAQUA WQ 300 water quality meter can be connected to different sensor electodres for measuring the parameter you want..
The following paramaters, each with its own sensor electrode are available with either a 2 meter or 5 meter cable.:
-
- pH(model 300PH-2 or 300PH-5)
- ORP (model 300-O-2 or 300-O-5)
- combination EC / TDS / Resisitivity / Salinity (model 300-C-2 of 300-C-5)
- Ion (model 300-I-2 or 300-I-5)
Next to one of the sensor heads you will also need a sensor electrode to enable you to measure the parameter of your choice. Please order the sensor electrode separately.
With the ION Sensor Head a BNC connector adapter will be supplied for connecting an ION electrode (all with BNC connector).
Note. For measuring DO (Dissolved Oxygen) no separate sensor head is available. For DO an electrode with integrated sensor head is available. See also under LAQUA 300 Sensor Electrodes.
