Level Indicator Strips: Never Be Caught Short Again

Size: 200mm by 20mm

Product code: LL-STRIP-200

Are you tired of running out of gas or essential liquids at the worst possible moment? Whether you're hosting a backyard barbecue, embarking on a camping adventure, or simply need to check the levels in various containers, our Level Indicator Strips provide a convenient and reliable solution for both gas and liquid monitoring.

How Level Indicator Strips Work

These innovative strips utilize advanced thermochromic technology to give you a visual representation of the level inside your container. Thermochromic materials change colour in response to temperature variations. This colour change accurately reveals the level of the substance within.

Here's a step-by-step guide on how to use them:

  1. Preparation: Ensure the surface of the container is clean and dry for optimal adhesion. If necessary, wipe the area with a clean cloth to remove any dust or debris.
  2. Application: Peel off the protective backing from the strip and carefully apply it vertically to the side of the container. Ensure the strip is in full contact with the surface and free of any air bubbles or creases.
  3. Activation: Apply heat to the strip using a hairdryer on a warm setting. Alternatively, you can use very hot (but not boiling) water. Move the heat source back and forth across the strip for a few seconds until you see a distinct colour change.
  4. Observation: The strip will change from its initial black colour to a vibrant orange. Once the heat source is removed, a portion of the strip will revert to black, indicating the approximate level of the substance inside. The point where the orange and black sections meet represents the level.

Important Considerations:

  • Temperature Sensitivity: The strips are designed to work optimally within a temperature range of 14°C to 40°C (57°F to 104°F). Outside of this range, the colour change may be less pronounced or slower to occur.
  • Accuracy: While the strips provide a helpful visual guide, they offer an approximate indication of the level. Factors such as container shape, ambient temperature, and substance type can influence the accuracy of the reading. Always exercise caution and use personal judgment when assessing levels, especially in critical situations.
  • Reusability: The strips are designed for multiple uses. However, the adhesive may lose its effectiveness after several applications. If the strip starts to peel, you can secure it with tape or a suitable adhesive.

Benefits of Level Indicator Strips

  • Eliminate Guesswork: Take the guesswork out of checking levels and avoid the inconvenience of running out unexpectedly.
  • Easy to Use: No complicated instructions or tools required. Simply apply, heat, and observe.
  • Cost-Effective: Reusable design saves you money and reduces waste compared to single-use alternatives.
  • Versatile: Suitable for various substances, including butane, propane, water, and other liquids compatible with the thermochromic material.
  • Compact and Portable: Lightweight and easy to store, making them ideal for various applications.

Applications

Level Indicator Strips are perfect for a variety of uses, including:

  • BBQs and Grills: Ensure you have enough gas for your next cookout.
  • Camping Stoves: Monitor fuel levels for cooking while camping or backpacking.
  • Propane Heaters: Check the propane level in your heater to avoid running out on a cold night.
  • Fire Extinguishers: Monitor the level of foam or water in fire extinguishers to ensure they are ready for use.
  • Water Tanks: Monitor water levels in RVs, boats, or storage tanks.
  • Other Liquid Containers: Check levels in various containers, such as those holding cleaning solutions, automotive fluids, or garden chemicals.
