High Accuracy pH Electrode with Calibration Powder (0-14 pH)

High Accuracy pH Electrode with Calibration Powder (0-14 pH)

This high-precision pH electrode is a combination electrode, integrating a pH measuring element with a silver chloride reference electrode for accurate pH value measurement in liquids. Featuring a BNC type socket and an extended 300cm long cable, this electrode allows for direct connection to your pH meter, pH controller, or any pH device equipped with a BNC input terminal. The replaceable design ensures you can re-use your meter portion indefinitely, making it a cost-effective choice for various applications.

Features

• Long cable replacement pH electrode for flexibility in measurements
• 50 Ohm BNC type connector for reliable connectivity
• Durable glass bulb for accurate pH readings
• Easy calibration using your pH measuring device
• Comes with a protective cap for safe storage
