Professional FAQ

• When should I choose a 9-meter probe?
  • Use long probes for large machines or distant junction boxes.
• Does hazardous approval affect probe size?
  • Approvals do not change dimensions or mounting requirements.
• Can this probe replace shorter 3300 models?
  • Yes, if the system calibration matches the 9-meter length.
• What causes unstable readings in the field?
  • Incorrect gap setting and cable damage cause most issues.
• How do I select the right approval option?
  • Match plant safety zone requirements with CSA, ATEX, or IECEx.
