## Description

Dometic GasChecker GC 100: Gas Level Pen : desertcart.co.uk: DIY & Tools

Review: Works well on a film set! - Great little gadget! I use this at work to know when gas bottles are about to run out. It can give false negatives but never a false positive so its important to not just take the first reading as gosple. By taking a few readings on different sides of the bottle and gently playing with the angle of the pen to the bottle you soon get good results. But it doesn't work if the bottle starts freezing up ... which is only fair ... so you need to scrape the ice off to get to bare metal first if you're running the bottle hard! :)
Review: Keep your dosh !!!! - Have never used this item before. I tried it at the weekend to show a friend, and it wouldn’t work properly: ie it showed red but never went green. I tried it on 3 different bottles, all full as l had only just bought them. Waste of money, don’t bother.

## Questions & Answers

**Q: Will this work on a LPG bottle**
A: I use it for my Motorhome on my Propane LPG bottle. Works very well!

**Q: Will this work on a 47kg bottle**
A: This works on any size

**Q: is it powered by replaceable battery?**
A: I purchased one of these units to check the level in my gas cylinder. I tried it on a 11kg Flow gas Cylinder and it worked once. When I tried it again it showed the cylinder empty when I knew it was full. I followed the instructions and made sure the gas cylinder was clean and also the tip of the unit was square onto the cylinder.I contacted the supplier and they replaced it with a new unit. I also tried the new one on a full gaslow-refillable cylinder and also on the flowgas cylinder and experienced the same problem. I contacted the supplier and they told me the unit would not work on the refillable cylinder due to the construction. They said that it may not work on the flowgas cylinder as they had only tried it on Calor cylinders. In the end I sent the unit back and they re-funded the money.

**Q: Can this item be returned if not suitable?**
A: This is what I’m using this for
