Probes

Probes — New & Used

Probes are critical sensing and measurement components used to monitor temperature, level, electrical signals, and process conditions across industrial equipment and lab setups. From temperature probes and thermocouples to test probes and process probes, they provide the front-end accuracy your control, monitoring, or test system depends on.

At Surplus Select, we stock a rotating inventory of new and used OEM probes, including temperature probes, immersion probes, test leads, and specialty industrial probes. Our inventory updates daily, offering surplus pricing for maintenance teams, OEMs, test labs, and integrators looking to replace failed probes or add measurement points without paying full catalog cost.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your Probe Fast (Search-First)

Search your part number or model (e.g., K-type temperature probe, immersion probe 1/4" NPT, oscilloscope probe 10:1).
No PN? Try specs like "RTD temperature probe 3-wire", "stainless steel temperature probe 6" stem", or "test probe kit 4mm banana".
Need a specific connection or range? Add details such as K-type, J-type, M12 connector, food-grade, or high-temperature to your search.

Applications & Use Cases

Process & industrial temperature monitoring: Use probes in tanks, lines, and equipment to measure and control process temperatures.
Test & measurement: Connect electrical probes to meters, scopes, and analyzers for troubleshooting and validation work.
OEM machinery & skids: Integrate probes into packaged systems to feed PLCs, controllers, and monitoring systems with accurate data.
Laboratory & R&D: Use probes to collect temperature or signal data during experiments, validation runs, and development work.
MRO & replacements: Swap failed or drifted probes with surplus OEM units to restore accuracy and minimize downtime.
