Gas Bottle Level Indicator, 3 Pcs Magnetic Gauge Strips for Propane LPG

Product features

1. 3 Piece Gas Level Set: You will receive 3 reusable magnetic gas bottle level indicators for checking compatible propane, butane and LPG cylinders, providing multiple gauge strips for caravan, motorhome, camping, BBQ, patio heater and home gas setups
2. Magnetic Bottle Attachment: Each magnetic gas level indicator attaches to a suitable steel gas cylinder without permanent installation. Position the strip on the lower outside area of the bottle and check that the cylinder surface attracts the magnet before use
3. Liquid Crystal Indicator: The gas bottle gauge uses a temperature-sensitive liquid crystal strip to provide a visible reference while gas is flowing, helping users check the approximate liquid level without removing the cylinder from a compatible appliance setup
4. For Caravan and Outdoor Use: The gas tank level indicator is suited to caravan and motorhome users, campers, BBQ setups and patio heaters using compatible steel propane, butane or LPG bottles, making it useful when checking gas supplies during trips or outdoor activities
5. Check Before Reading: Attach the strip to a clean, dry steel cylinder and read the indicator while gas is being used. Results can vary with cylinder material, surface condition, temperature, weather and gas flow, so use the strip as a level reference rather than a precise measuring instrument
