It provides a stable pH 6.86 reference value so you can calibrate electronic pH probes and keep daily measurements accurate and repeatable.\n<\/p>\n<h3>Use of pH 6.86 buffer solution<\/h3>\n<p>\nElectronic pH meters gradually drift because probe surfaces age and are exposed to chlorinated water, chemicals and temperature variations. Calibrating with a Meytec buffer solution pH 6.86 allows you to correct this drift close to the operating range of most pool waters, where the target pH is usually around neutral.\n<\/p>\n<p>\nIn many calibration routines, this pH 6.86 buffer is used as the central reference point and combined with additional acidic or alkaline buffers, such as pH 4.01 or pH 9\u201310, to refine the meter response across the full working range.\n<\/p>\n<h3>250 ml design bottle for regular calibration<\/h3>\n<p>\nThe Meytec buffer solution pH 6.86 bottle 250 ml is supplied in a practical screw cap bottle that is suitable for users who calibrate their instruments frequently. The 250 ml volume offers a good balance between quantity and shelf life for service partners, technicians and pool operators.\n<\/p>\n<ul>\n<li>250 ml of ready to use pH 6.86 buffer solution.<\/li>\n<li>Design bottle with secure cap for repeated opening and closing.<\/li>\n<li>Suitable for bench meters, handheld testers and fixed controllers.<\/li>\n<\/ul>\n<p>\nTo maintain the specified pH value, only small working volumes should be poured into a clean container for each calibration and the main bottle should be reclosed immediately after use.\n<\/p>\n<h3>Calibration with Meytec pH 6.86 buffer<\/h3>\n<p>\nThe Meytec buffer solution pH 6.86 bottle 250 ml is compatible with most pH meters that accept external buffer solutions. It is intended for calibration and verification of pH probes in residential and commercial pools, spas and other installations where reliable pH control is essential.\n<\/p>\n<ul>\n<li>Neutral reference point close to the recommended pool pH.<\/li>\n<li>Supports precise adjustment of pH probes in water treatment applications.<\/li>\n<li>Can be used alone or as part of a multi point calibration routine.<\/li>\n<\/ul>\n<p>\nFor best results, the calibration sequence and buffer values should follow the instructions provided by the instrument manufacturer, including stabilisation time and temperature compensation where required.\n<\/p>\n<h3>Example calibration procedure<\/h3>\n<p>\nA simple calibration using Meytec pH 6.86 buffer can be carried out either as a single point adjustment near the operating value or as part of a multi point procedure together with additional buffers.\n<\/p>\n<ul>\n<li>Rinse the pH probe with clean water and gently dry with a soft cloth.<\/li>\n<li>Pour a small amount of pH 6.86 buffer into a clean container.<\/li>\n<li>Immerse the probe and wait until the reading is stable.<\/li>\n<li>Adjust the meter to 6.86 according to the calibration menu.<\/li>\n<\/ul>\n<p>\nWhen used as the central point in a multi point calibration, the pH 6.86 buffer is combined with lower and higher reference solutions so the meter can correct both offset and slope over a wider pH range.\n<\/p>\n<h3>Storage and handling recommendations<\/h3>\n<p>\nTo keep the Meytec buffer solution pH 6.86 bottle 250 ml within specification, it should be stored in a cool, dry place away from direct sunlight and heat sources. Good handling practices help avoid contamination and extend the useful life of the solution.\n<\/p>\n<ul>\n<li>Always close the bottle tightly immediately after dispensing.<\/li>\n<li>Use only clean containers and never return used buffer to the bottle.<\/li>\n<li>Avoid contact with pool water, dirt or other chemicals.<\/li>\n<\/ul>\n<p>\nWith correct storage and regular calibration, this buffer solution helps maintain accurate pH readings, supports stable dosing control and contributes to comfortable, well balanced pool and spa water.<\/p>","protected":false},"excerpt":{"rendered":"<p>Meytec buffer solution &#8211; pH 6.86 &#8211; bottle 250 ml The Meytec buffer solution pH 6.86 bottle 250 ml is a neutral calibration liquid for pH meters and controllers used on swimming pools, spas and other water treatment systems.
