Feature: 1. The sensor probe adopts non‑contact induction, safe to use and long life. 2. The stainless steel bracket is convenient to adjust the measuring head, and the light way must be unobstructed during adjustment. 3. The electrical wire adopts high‑quality tinned shielded wire, and the signal output is fast and stable. 4. The metal shell comes with M18×1 threaded fixing installation, double nut installation, convenient disassembly and assembly. 5. With small size, easy to carry and store, convenient to use and with good percompatible withmance.
