It provides a stable reference at 475 mV so you can check and adjust electronic probes, keeping oxidation reduction<br \/>\npotential readings accurate over time.\n<\/p>\n<h3>Role of a 475 mV redox buffer<\/h3>\n<p>\nOrp and redox probes slowly drift because of ageing, chemical exposure and temperature changes. Calibrating the instrument with a known<br \/>\nMeytec RX 475 mV buffer solution allows you to verify that the probe response is correct in the typical working zone for disinfected pool<br \/>\nwater, where orp control is often used to modulate chlorine dosing.\n<\/p>\n<p>\nUsing a fixed millivolt reference value helps you detect probe wear or contamination early and avoid relying on measurements that no<br \/>\nlonger reflect the true disinfection potential of the water.\n<\/p>\n<h3>Single use 20 ml sachet format<\/h3>\n<p>\nThe Meytec buffer solution RX 475 mV sachet 20 ml is supplied in a sealed single dose pouch. The buffer is opened only at the moment of<br \/>\ncalibration, which limits contact with air and contaminants that could change the reference value in multi use bottles.\n<\/p>\n<ul>\n<li>Individual 20 ml volume for one calibration or check.<\/li>\n<li>Factory sealed to preserve a stable 475 mV reference.<\/li>\n<li>Compact and easy to carry for on site service work.<\/li>\n<\/ul>\n<p>\nUsing a fresh sachet for each calibration supports repeatable results, especially where the orp signal is used to control automatic<br \/>\ndosing pumps in residential or small commercial pools.\n<\/p>\n<h3>Use with orp and redox meters<\/h3>\n<p>\nThis Meytec RX 475 mV buffer solution is compatible with most handheld orp testers, redox controllers and multi parameter instruments<br \/>\nthat accept external calibration solutions. It is suitable for systems that monitor disinfectant potential in chlorinated or brominated<br \/>\nwater.\n<\/p>\n<ul>\n<li>Calibration liquid for electronic orp and redox meters.<\/li>\n<li>Helps verify the response of probes used for pool disinfection control.<\/li>\n<li>Useful for periodic checks of automatic dosing installations.<\/li>\n<\/ul>\n<p>\nAlways follow the calibration or verification procedure given by the instrument manufacturer, including any steps for temperature<br \/>\ncompensation and immersion time in the buffer.\n<\/p>\n<h3>Example verification procedure<\/h3>\n<p>\nDepending on the device, the RX 475 mV buffer can be used either for full calibration or for a simple verification of probe accuracy. A<br \/>\ntypical quick check uses the sachet to confirm that the meter reading remains close to the stated 475 mV value.\n<\/p>\n<ul>\n<li>Rinse the orp probe with clean water and gently dry.<\/li>\n<li>Open the Meytec RX 475 mV sachet 20 ml and pour into a clean cup if needed.<\/li>\n<li>Immerse the probe and wait for the reading to stabilise.<\/li>\n<li>Compare the displayed value to 475 mV and adjust only if allowed by the device.<\/li>\n<\/ul>\n<p>\nIf the reading deviates significantly from the reference and cannot be corrected, the probe may be contaminated or near the end of its<br \/>\nservice life and should be cleaned or replaced.\n<\/p>\n<h3>Storage and handling recommendations<\/h3>\n<p>\nTo maintain its certified reference value, the Meytec buffer solution RX 475 mV sachet 20 ml should be stored in a cool, dry place away<br \/>\nfrom direct sunlight. Each sachet is intended for single use, and any remaining liquid after calibration should be discarded.\n<\/p>\n<ul>\n<li>Keep sachets sealed until just before the calibration step.<\/li>\n<li>Avoid mixing the buffer with pool water or other chemicals.<\/li>\n<li>Dispose of used sachets and leftover liquid in line with local rules.<\/li>\n<\/ul>\n<p>\nCombined with correct probe cleaning and periodic replacement, regular use of Meytec RX 475 mV buffer solution helps keep redox based<br \/>\ncontrol systems reliable and supports stable water disinfection throughout the season.<\/p>","protected":false},"excerpt":{"rendered":"<p>Meytec buffer solution &#8211; RX 475 mV &#8211; sachet 20 ml The Meytec buffer solution RX 475 mV sachet 20 ml is a single use calibration liquid for orp and redox meters used on pool, spa and water treatment systems.
