300cm Cable PH Probe. 100% BNC connector, suitable for most pH meters and controllers with BNC connector. Suitable for a wide range of applications: aquariums, hydroponics, laboratories, etc. Measurement range: 0.00–14.00 pH. Caution: Not suitable for testing in highly viscous liquids or for continuous testing in high-temperature solutions. Not suitable for testing low ionic concentration solutions (such as deionized or distilled water) or strong alkaline solutions (pH above 12). pH Replacement Probe with BNC Interface and 300cm Cable: Our pH electrodes are designed for pH measurements in general water applications such as drinking water, aquariums, fish tanks, swimming pools, hydroponics, irrigation water, scientific research, environmental monitoring, laboratories, spas, wastewater, and industrial water testing. The standard BNC connector is compatible with any pH meter that uses a BNC connector. Measuring range: 0–14 pH. Features automatic temperature compensation (0–50°C), enabling fast and stable pH readings and reliable performance across various pH testing needs. pH Probe Diameter: 12mm Zero point: 7 ± 0.5 pH Accuracy: ±0.2 pH Theoretical Percentage Slope: ≥98.5% Internal Resistance: ≤250MΩ Response Time: ≤1 minute Operating Temperature: 0–60°C Connector: BNC plug Cable Length: 300cm Please verify specifications to ensure compatibility with your equipment.
