Frequently Asked Questions (FAQ)

• Q: Does this probe work with existing 3300 monitoring systems?
  A: Yes, the 3300 XL 8mm Probe series fully complies with 3300 XL system requirements.
• Q: Can I extend the total cable length?
  A: You can add extension cables, but the total system length must not exceed 9 meters for specified accuracy.
• Q: Is the probe suitable for oil-filled environments?
  A: The standard probe resists oil; the FluidLoc option prevents internal liquid leakage.
