Truma LPG Gas Level Indicator

The Truma 50501-01 LPG gas level checking device is used on the exterior of any standard gas cylinder (with a diameter of 200mm to 350 mm) and indicates whether there is gas at the point of measurement.

Please note the Truma gas level checker is NOT suitable for checking gas levels on Calor 6kg Lite cylinders with the built-in gas level gauge because the magnet inside the Calor 6 kg Lite interferes with the signal emitted by the pen.
