The HM Digital SP-2 is the matched pair of replacement in-line sensor probes for HM Digital's dual-line monitors. Stainless-steel electrodes in ¼" bodies sized for quick-connect fittings, on a short shielded lead terminating in a single 8-pin connector.
The two sensors are wrapped blue and red and labelled IN and OUT, so feed and product lines cannot be transposed during installation. Supplied as a pair — HM Digital lists this probe set for the DM-1.
