DESCRIPTION

• This Liquid pH Electrode Probe with Amplifier is designed to accurately measure the acidity or alkalinity of aqueous solutions, making it essential for water quality testing and chemical analysis.
• The probe uses a glass electrode filled with electrolytes to generate a voltage proportional to the hydrogen ion concentration in the solution.
• The included pH signal conditioning amplifier converts the weak millivolt signal from the probe into a stable analog output, ideal for microcontroller ADC pins.
• Suitable for continuous pH monitoring, with high stability and low drift.
• Ideal for aquariums, hydroponics, water treatment plants, laboratories, and environmental monitoring setups.
• The durable BNC probe design ensures reliable long-term measurements and easy replacement when needed.
• Works seamlessly with common development boards for DIY pH meters, IoT dashboards, and automated dosing systems.
