Options & Accessories |
Model 133-7-1 Waterproof Version (Part Number 47-2453) - Waterproof versions have the same characteristics as non-waterproof models, other than they are waterproof, contain an O-ring, and do not have a “C” connector on the probe end (base). A 100 ft (30 m) cable is hard-wired into the detector. They weigh slightly more and have a slightly larger diameter than the non-waterproof versions.
