## Questions & Answers

**Q: Will this device detect ethanol?**
A: It will respond to ethanol vapor, but will not be very representative of the actual %LEL since this detector, like all, are calibrated standard to methane. If you need %LEL for ethanol we will need to special order for accurate ethanol %LEL. Thank you.

**Q: Does this unit have a belt clip or some other means with which to attach it to an individual?**
A: Yes come with an aligator belt clip.

**Q: Do you have any device that we can analyze the CO gas from vehicle**
A: No unfortunately we do not. Existing products from other companies seem to be OK options.

**Q: Conflicting info for battery life. "working battery time	> 24 hours" or "average battery life	‎6 hours". which is it? thanks!**
A: Thanks for bringing it to our attention. Battery life is well over 24 hours!
We will fix the Amazon-generated typo. Have a great day.
