## Questions & Answers

**Q: How can this unit provide an evacuation function but the unit does not accurately measure microns and requires a separate micron gauge?**
A: You need a separate micron gauge

**Q: Is the warranty valid outside the US?**
A: I don't know I would think so you would have to ship it back to were you bought it .

**Q: Do the games measure microns? or is the separate probe a must?**
A: It will measure microns internally though the hoses. The probs only measure line temps. I have the wireless versions and the kit comes with the micron sensor

**Q: do this kit has hoses?**
A: No. Hoses are separate.
