Model LP3100 is a linear polarization resistance probe commonly used in laboratory,
bypass-loop, and field applications. The assembly consists of a 1" NPT compression
fitting, an insertion rod with a hermetically sealed three-electrode endcap, and a
five-pin military connector mounted 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. This maximum I.L. is based on the
length of a carbon steel electrode. Electrode lengths may vary depending on the
alloy. Electrodes are ordered separately.
