This replacement probe features a standard BNC connector that is universally compatible with virtually all pH meters, ORP meters, and pH controllers that use a BNC interface. If your device has a BNC port, this probe will connect directly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is automatic temperature compensation (ATC) and why does it matter?\u003c\/h4\u003e\n\u003cp\u003eA: Automatic Temperature Compensation (ATC) automatically adjusts pH readings based on the current water temperature (0–50°C range). This is important because temperature significantly affects electrode response — ATC ensures your pH readings remain accurate without manual correction, which is especially useful in aquariums, hydroponics systems, and outdoor pool testing.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this probe measure ORP as well as pH?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This is a combination electrode that functions as both a pH electrode and an ORP (oxidation-reduction potential) probe. The silver chloride reference electrode makes it suitable for measuring the ORP of water and aqueous solutions using a compatible ORP meter.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How should I store and maintain this pH electrode to extend its lifespan?\u003c\/h4\u003e\n\u003cp\u003eA: When not in use, keep the electrode tip immersed in a storage solution (typically pH 4.01 buffer or KCl solution) and avoid allowing the glass bulb to dry out. Rinse the probe with distilled water before and after each use. Regular calibration using the included pH 4.01 and 6.86 buffer solutions will ensure ongoing measurement accuracy.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this pH ORP probe compatible with my existing BNC pH meter or controller?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
