I am a truck driver, and it is ideal to give an idea of the level of the propane bottle. It is of course not 100% reliable, it depends on the quality of the bottle in general. But it still avoids bad surprises, like no more gas on a Sunday ....
Very good product, easy to use. It will allow me to have an idea of the consumption of a bottle of 13 kg when renting my camper. \ R \ nNot yet understood the change of the pile. (afraid to break something !!) \ r \ n
I tried this product to assess the capacity of 2 butane gas bottles of 13 KG. One full and one half full. The Gas Checker gave me no valid indication. red wherever it was applied. Very disappointed with this product.
