TFA Dostmann 98.1127 Magnetic Gas Level Indicator Reusable Easy to Read Black

Product description

• Magnetic: simply attach the level gauge to standard steel gas bottles such as propane or butane with the magnetic back
• Use: place the magnetic gas level indicator in the lower part of the steel gas bottle, after approx. 10 minutes of gas removal, you can read an exact display of the filling level
• Display: the analogue display of the liquid crystals change their colour at different temperatures, if the colour gradient of the strip from top to bottom is not continuous, at this point the level is between liquid and gas phase
• Gas level indicator: shows the temperature difference in the bottle when the liquid gas evaporates, resulting in the interruption of the strip to the right
• Reusable: the level indicator can be used over and over again, shows a low gas level before the gas is empty
