If the LED indicator lights green, gas is present. If it lights red, there is no gas. So the exact level can be easily determined. TRUMA LEVEL CHECK ADVANTAGES - Integrated LED torch for gas control in the dark. Automatic shut-off after measurement. Always ready: measurement in the temperature range from -15 to +40 degrees possible. UNIVERSAL - Suitable for all standard European steel and aluminium gas cylinders with a diameter of 200-350 mm. The LevelCheck is not suitable for plastic gas bottles, fillable tank gas bottles, gas tanks or butane gas bottles. International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
The Truma LevelCheck is designed for RVers and campers who need a quick and reliable way to check their gas bottle levels. Its key benefit is the simple ultrasound measurement that provides an instant green (gas present) or red (no gas) indicator, preventing unexpected outages. A caveat is its limited compatibility, as it is not suitable for plastic, refillable tank, or butane gas bottles. This device offers an integrated LED torch for dark conditions and automatic shut-off.

Extended Product Information
FAQs
How does the Truma LevelCheck work?
It uses ultrasound technology to measure the gas level within the cylinder. It indicates whether gas is present at the measurement point or not.
What types of gas bottles is the LevelCheck compatible with?
It is compatible with standard European steel and aluminum gas cylinders with a diameter of 200 mm to 350 mm. It is not suitable for plastic, refillable tank, gas tank, or butane gas bottles.
Does it show the exact amount of gas left?
No, the LevelCheck only indicates whether gas is present or absent at the point of measurement, not a precise volume or percentage.
How do I know if the battery needs replacing?
If the device does not power on or shows weak performance, the battery likely needs replacement. The device uses a standard coin cell battery.
Can I use the LevelCheck in very cold or hot weather?
Yes, the device is designed to operate reliably within a temperature range of -15°C to +40°C.
Is the LED torch a separate function?
No, the LED torch is integrated into the device and activates automatically when the measurement button is pressed, aiding visibility during use.
What happens after I take a measurement?
The device automatically shuts off shortly after the measurement is taken to conserve battery power.
Troubleshooting
Device does not turn on or show any light.
Ensure the battery is correctly inserted and has sufficient charge. Replace the battery if necessary.
Inconsistent readings (flickering lights or changing colors).
Ensure the LevelCheck is held vertically and pressed firmly against the gas cylinder. Check for any obstructions on the cylinder surface or the device sensor.
Red light shows, but gas is suspected to be present.
Verify that the gas cylinder is compatible (steel or aluminum, 200-350mm diameter). Ensure the device is placed at the correct height on the cylinder; the reading indicates gas *up to* that point.
Device turns off immediately.
This is normal behavior due to the automatic shut-off feature. Press the button again to take a new measurement.
