It provides a stable reference at pH 4.0 so you can verify and adjust electronic pH probes and keep daily measurements reliable.\n<\/p>\n<h3>Purpose of the pH 4.0 buffer solution<\/h3>\n<p>\nElectronic pH meters and controllers gradually drift over time because probes age and are exposed to treated pool water and temperature changes. Calibrating them with a known Meytec pH 4.0 buffer solution restores accuracy, so dosing decisions are based on correct readings instead of approximate values.\n<\/p>\n<p>\nThis Meytec buffer solution pH 4.0 sachet 20 ml is usually used together with a pH 7.0 buffer solution in a two point calibration. The pair covers the most important pH range for pools and spas and helps compensate for probe drift.\n<\/p>\n<h3>Single use 20 ml sachet<\/h3>\n<p>\nThe calibration liquid is supplied in a sealed 20 ml sachet that is opened just before use. This single dose packaging limits contact with air and contamination, which can otherwise alter the pH value over time in opened bottles.\n<\/p>\n<ul>\n<li>Individual 20 ml volume for one full calibration sequence.<\/li>\n<li>Factory sealed to maintain a stable pH 4.0 reference value.<\/li>\n<li>Convenient format for occasional users and mobile service technicians.<\/li>\n<\/ul>\n<p>\nUsing a fresh sachet for each calibration helps keep digital pool testers and pH controllers as accurate as possible, especially when they are used to drive automatic dosing systems.\n<\/p>\n<h3>Use with pool pH meters and testers<\/h3>\n<p>\nThe Meytec buffer solution pH 4.0 sachet 20 ml is compatible with most handheld pH meters, controllers and combined photometers that allow external calibration. It is suitable for residential pools, spas and small commercial installations where regular pH checks are required.\n<\/p>\n<ul>\n<li>Calibration liquid for electronic pH meters, pens and desktop testers.<\/li>\n<li>Supports accurate adjustment of pH probes used in pool and spa water.<\/li>\n<li>Useful for control units that regulate acid or pH minus dosing pumps.<\/li>\n<\/ul>\n<p>\nAlways follow the calibration procedure of the specific instrument, including temperature compensation and careful rinsing between buffers.\n<\/p>\n<h3>Example of a two point calibration<\/h3>\n<p>\nProcedures differ by device, but the general method for using Meytec pH 4.0 buffer together with a pH 7.0 buffer is similar on most portable testers. Two point calibration improves accuracy across the typical pool pH range.\n<\/p>\n<ul>\n<li>Rinse the pH probe with clean water and dry gently with a soft cloth.<\/li>\n<li>Open a pH 7.0 buffer sachet, immerse the probe and confirm or adjust the reading.<\/li>\n<li>Rinse the probe to avoid mixing buffer solutions.<\/li>\n<li>Open the Meytec pH 4.0 buffer sachet 20 ml, immerse the probe and confirm or adjust to 4.0.<\/li>\n<li>Rinse the probe again before resuming normal pool water measurement.<\/li>\n<\/ul>\n<p>\nThis two point method ensures the meter reads correctly at both neutral and acidic reference points, which stabilises readings within the operational range used for pool treatment.\n<\/p>\n<h3>Storage and handling<\/h3>\n<p>\nTo maintain the certified pH value, the Meytec buffer solution pH 4.0 sachet 20 ml should be stored in a cool, dry place away from direct sunlight. Each sachet is intended for single use and any remaining solution should be discarded after calibration.\n<\/p>\n<ul>\n<li>Keep sachets sealed until just before calibration.<\/li>\n<li>Avoid contact between the buffer and pool water to prevent contamination.<\/li>\n<li>Dispose of used sachets and leftover liquid according to local regulations.<\/li>\n<\/ul>\n<p>\nRegular calibration with fresh Meytec buffer solution helps extend probe life and keeps your pH readings dependable throughout the swimming season.<\/p>","protected":false},"excerpt":{"rendered":"<p>Meytec buffer solution &#8211; pH 4.0 &#8211; sachet 20 ml The Meytec buffer solution pH 4.0 sachet 20 ml is a single use calibration liquid for pH meters and testers used on swimming pool and spa water.
