Frequently Asked Questions (FAQ)

• Q: What is the condition and warranty of this probe?
  A: Every probe is new, original, and comes with a full 12-month factory warranty.
• Q: Does this 0.5m probe need an extension cable?
  A: No, one-meter (and shorter) systems like this 0.5m model integrate the cable and do not need an extension.
• Q: What makes the 8mm probe more robust?
  A: The larger diameter allows for thicker PPS plastic around the coil and a stronger stainless steel case.
• Q: What is the key feature of the CableLoc design?
  A: It mechanically secures the cable to the probe body, providing a high 330 N (75 lbf) pull-out resistance.
• Q: Can this probe be used in hazardous areas?
  A: Yes, the model with suffix 05 holds CSA, ATEX, and IECEx approvals for such environments.
