Model LP2000 is a fixed-length, linear polarization resistance probe with
an NPT pipe plug. The probe requires process isolation or process shutdown to install and
a threaded pipe fitting to mount. The probe assembly consists of an insertion rod with a
two-electrode endcap, a hermetically sealed connector, and an NPT pipe plug which are all
welded in place. The insertion length (I.L.) is calculated to the end of the electrode and
can be specified by the customer. For standard probes, the maximum insertion length is
given in the chart below. Electrodes are ordered separately. Several standard electrodes
are available to meet your specific needs.
