## Questions & Answers

**Q: Do you sell a unit like this unit that also test for CO2?**
A: Analox does not make a handheld model that analyzes for CO2.  If you mean a carbon monoxide handheld analyzer, you will want to look for a Palm CO (carbon monoxide) analyzer.

**Q: Can user change battery?**
A: Hello,Yes the user can replace the batteries.  You can find the procedure on the Analox site within their manual on page 19.Per the manual it involves: "1. Loosen the 4 screws located on the front cover. The gasket seal is designed to prevent water leaking into the O2 EII Pro, as a result, the seal may be tight. Loosen the seal by moving the lid from side to side, and then carefully lift the cover.  2. Slide the battery out of its holder and disconnect the lead.  3. Connect the lead to the new battery and slide the battery into its holder, under the battery clip.  4. Replace the cover carefully, taking care that the sensor locates properly and that you do not trap any wires. Screw down until you feel the gasket tighten; do not over tighten the screws."So it is pretty easy.Let us know if you need anything further.  Secondly we do sell the product with your choice of black, yellow, blue or red Pelican 1050 case with pick and pluck foam for $289.99, let me know if you'd like that offer.Regards,Wayne,Founder & CEO

**Q: Does this come as a kit with the pelican storage case and small attachment hose? I can’t seem to find it as a kit on Amazon**
A: Thanks for your question! 

This listing is for the analyzer only, a carrying case or box by another brand will have to be purchased separately.

Thank you,

HouseofScuba

**Q: Can the included "domed adapter with hose barb" be used to obtain a reading directly from the nitrox tank?  If so, do you need to plug the hose barb?**
A: Thank you for your question.  You can take a reading directly from the nitrox tank, without having to plug the hose barb.
