pH & ORP Replacement Probe – 300cm BNC Cable, Auto Temp Compensation
pH & ORP Replacement Probe with 300cm BNC Cable
Upgrade your water quality monitoring setup with this precision pH & ORP Replacement Probe. Featuring a generous 300 cm (3-meter) cable and a universal BNC connector, this probe is compatible with virtually any pH meter or controller that uses a BNC interface. Automatic Temperature Compensation (ATC, 0–50°C) ensures stable, accurate readings across a wide range of environments. Made in Mainland China.
Key Features
- Universal BNC Compatibility: Plugs directly into any pH meter, ORP controller, or water quality tester with a BNC connector — no adapters needed.
- Wide Measuring Range: Covers 0.00–14.00 pH for comprehensive testing across acidic, neutral, and alkaline solutions.
- Automatic Temperature Compensation (ATC): Compensates for temperature variations (0–50°C) to deliver consistent, reliable readings.
- Extra-Long 300cm Cable: Ideal for reaching into deep tanks, reservoirs, or hard-to-access systems without moving your meter.
- Dual-Purpose pH & ORP Probe: Functions as both a pH electrode and an ORP (Oxidation-Reduction Potential) combination electrode, featuring an indicator electrode and silver chloride reference electrode.
- Versatile Applications: Suited for aquariums, fish tanks, swimming pools, hydroponics, irrigation systems, kombucha brewing, spas, laboratories, and wastewater monitoring.
- Fast Response: Delivers stable readings within 1 minute of submersion.
- Durable ABS Construction: 12mm diameter probe body built to withstand regular use in wet environments.

Frequently Asked Questions
Q: Is this pH & ORP probe compatible with my existing BNC pH meter?
A: Yes. This replacement probe uses a standard BNC connector, making it compatible with virtually all pH meters, ORP controllers, and water quality analyzers that feature a BNC interface — including most popular lab and hobbyist models.
Q: What applications is this pH probe best suited for?
A: This probe is designed for a wide variety of water quality testing needs, including aquariums, fish tanks, swimming pools, hydroponics systems, irrigation water, kombucha brewing, spa water, laboratories, and industrial or wastewater monitoring.
Q: What does Automatic Temperature Compensation (ATC) mean for my measurements?
A: ATC automatically adjusts the pH reading based on the current water temperature (0–50°C), so you get accurate and consistent results without needing to manually factor in temperature changes — particularly important in environments where water temperature fluctuates.
Q: Does this probe measure ORP as well as pH?
A: Yes. This is a combination electrode that functions as both a pH electrode and an ORP (Oxidation-Reduction Potential) probe. The ORP function uses an indicator electrode paired with a silver chloride reference electrode to measure the oxidation-reduction potential of aqueous solutions.
