Gas Level Indicator Magnetic Butane Propane Calor LPG

Magnetic Gas Level Indicator for Butane or Propane LPG Gas Bottles

Simply place the magnetic indicator onto a clean area of your LPG gas bottle - works with all butane and propane gas bottles - and allow a few moments for the temperature to register on the reading area. The clever liquid crystal materials react to the internal temperature to show the level of the liquified gas within, so you'll know how much gas you have left in the bottle, easy.

Features
The gas residue test card uses PET and Liquid Crystal material to complete a visual colour change based on the internal temperature of the liquid gas transition inside the gas bottle. Color changes according to temperature changes, indicating the liquid gas position.
