Start by:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Unplugging the Electrical Connector<\/strong>: Located at the back of the sensor.<\/li>\n\n\n\n<li><strong>Removing the Sensor<\/strong>: Pull it out gently, and the O-ring seal will release it smoothly.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">With the sensor in hand, let\u2019s move on.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Step 2: Replace the Membrane<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">To access the membrane and solution:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Unscrew the Ring and Remove the Membrane<\/strong>: Take off the ring, discard the old membrane, and empty any remaining electrolyte.<\/li>\n\n\n\n<li><strong>Prepare the New Membrane<\/strong>: Retrieve a new membrane from its container, removing the yellow protective paper.<\/li>\n\n\n\n<li><strong>Insert the New Membrane<\/strong>: Place the clear membrane inside the ring and secure it by threading the ring and cap back together until fingertight.<\/li>\n<\/ol>\n\n\n\n<h5 class=\"wp-block-heading\">Step 3: Add Electrolyte Solution<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">With the new membrane in place:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Fill the Cap with Electrolyte Solution<\/strong>: Fill to the bottom of the threads.<\/li>\n\n\n\n<li><strong>Prepare the Sensor for Reassembly<\/strong>: Remove the small side screw for easier reattachment.<\/li>\n<\/ol>\n\n\n\n<h5 class=\"wp-block-heading\">Step 4: Reassemble the Sensor and Cap<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">To ensure the sensor functions correctly:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Attach the Cap at a 45\u00b0 Angle<\/strong>: Thread the sensor and cap together, allowing some electrolyte to spill out\u2014this is normal.<\/li>\n\n\n\n<li><strong>Tighten Until Sensor Contacts the Membrane<\/strong>: Tighten until the sensor tip just touches the membrane.<\/li>\n\n\n\n<li><strong>Replace the Small Plastic Screw<\/strong>: Reinsert and gently tighten the screw.<\/li>\n<\/ol>\n\n\n\n<h5 class=\"wp-block-heading\">Step 5: Reinstall the Sensor<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">Once assembled:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Reconnect to the Flow Cell<\/strong>: Press the sensor back into the O-ring seal.<\/li>\n\n\n\n<li><strong>Plug in the Electrical Connector<\/strong>: Reattach the connector.<\/li>\n<\/ol>\n\n\n\n<h5 class=\"wp-block-heading\">Warm-Up and Calibration Tips<\/h5>\n\n\n\n<p class=\"wp-block-paragraph\">After changing the electrolyte solution, allow the sensor a few hours to warm up before calibration. Trying to calibrate during warm-up may result in shifting readings. In some setups, replacing the electrolyte solution and membrane alone restores calibration without adjustments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more technical details, see our pages on the <a href=\"https:\/\/www.oxidationtech.com\/q45ph-orp.html\">Q45 Sensor<\/a> and the <a href=\"https:\/\/www.oxidationtech.com\/q46r-orp.html\">Q46 Sensor<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Watch our <a href=\"https:\/\/youtu.be\/biaV6rywUqk?si=utIa3a3b31yn6q2a\">video tutorial<\/a> for a full demonstration!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dissolved ozone sensors, like the Q46 and Q45 models, require regular maintenance to maintain accuracy.
