Replacement probe parts for Geotech ET and ETL water level meters.

• Probe Assembly (5/8") — the complete field-serviceable 5/8" probe with stainless steel conductors. Fits ET, ETL, and the deep rewind reels. Because it's field serviceable, you replace the probe without replacing the tape.
• Delrin Probe Tip (3/8") — replacement tip for 3/8" probes.

If your meter has a 3/8" probe and the probe itself has failed, note that the 3/8" probe is not field replaceable — it comes permanently attached to a tape. See the 3/8" options on the ET or ETL replacement tape listings.

Rebuilding a probe? You'll likely also want the O-ring and wave washer.
