Product Description

Ever been caught short with an empty gas cylinder? There's usually no way of telling how much gas is left. Just place the gas level indicator (GLI) on the bottom half of the cylinder switch on the gas.... Crystals change colour as gas runs low. No more returning of half full bottles! Can be used on any size propane, butane or mixed fuel gas gas cylinders. It is ideal for Leisure or Domestic use. Thousands are sold round the world each year. Can be used all year round You won't get caught short of gas again! * Safe, * Dependable, * Use today.....every day, * Re-use again and again! Thinner than a credit card and 114 x 50mm, the GLI's magnetic backing means it can be attached to the outside of the cylinder. We use a high quality magnet backing, that with careful use should last the life of the indicator. The GLI is designed as a warning device which shows when the gas bottle is running out. Packaged with full instructions and the science of how it works. Our new stock of Bottle shaped indicators are made in the USA with the latest liquid crystal technology. We do NOT supply rectangular indicators from Asia.
