Horiba W-20 Series Water Quality Instruments
P/N 530511-2(U22), 201031-1(W22XD)

Horiba W-20 Series are great instruments for in-situ measurements in wells, streams, lakes, and ponds. Different cable lengths offer versatility for each sampling situation. Years of Horiba sensor technology development have reached their culmination in the form of a 46-mm diameter sensor probe.
In addition to the Water Quality Monitoring System's own capabilities, it was designed by Horiba to be compatible with GPS and other data processing techniques. And now, the W-20 series is available with a detachable cable and flow through cell designed by Horiba. Learn more about the W-23XD.
