Model LP2000

Linear Polarization Resistance Probe
Fixed Length with NPT Pipe Plug & 2-Electrode Endcap

View PDF version


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.
