4. Measure your Gas with this level indicator, simply attach it to your gas tank cylinder with this magnetic Gas Level Indicator and it will show you how much gas is left in your tank.

Working principle:
1. the temperature of the upper gas is high, and the temperature of the lower gas is low. Depending on the color segmentation of the product, the position of the boundary line is where the gas is located.
2. When testing the product, test it with the gas bottle open and test it while using it.
3. Because this product is used to test whether the gas is used up or not, the product is attached to the bottom of the bottle and can only 4. be measured when the gas is running out.
If the gas is above the test card, the test result is wrong, the buyer can put a few sheets of the product on the gas bottle.
