Recommendations for Optimal Use and Care of the PreAsion Tester

Recommendations for Optimal Use and Care
To maximize the effectiveness of our tester, we recommend adhering to the following best practices during operation. First, ensure that the Ozone reagents A and B are purchased separately, as they are essential for accurate readings but are not included in the package. Always use freshly prepared reagents for testing to guarantee reliable results. When handling the unit, maintain it in a clean, dry area to prevent damage, and remember to keep the device away from direct sunlight for prolonged periods, which can affect its calibration and lifespan.
In terms of maintenance, we should regularly check the unit’s battery levels to ensure optimal performance. Since this device operates on dry batteries (which are not included), keeping spares on hand is advisable. After each use, we must clean the components gently to prevent buildup from the reagents. For storage, safeguard the tester in its original protective case to keep it safe from accidental bumps or drops. Additionally, refer to the manufacturer guidelines for periodic calibration to maintain accuracy.
