Supmea pH Sensor Signal Amplifier

Maximize Signal Stability for Reliable pH Measurement

The Supmea pH Sensor Signal Amplifier is an essential field accessory designed to solve the common challenges associated with high-impedance pH measurement. By converting the sensitive, high-impedance millivolt output of a pH sensor into a robust, low-impedance signal, this unit allows for reliable data transmission over extended cable runs without signal degradation.

Compatible with any standard pH electrode, this conditioner acts as a powerful buffer, making your measurement system immune to the electrical noise and interference typical in industrial environments. It functions as a simple, transparent mV-in / mV-out device, ensuring compatibility with virtually any pH meter or controller.

Key Features & Benefits

• Impedance Conversion: Transforms the extremely high impedance signal (typical of glass pH electrodes) into a stable low-impedance output. This allows the use of standard, unshielded cabling for longer distances, and even the use of a standard mV input on PLC or data acquisition IO.

• Universal Compatibility: Works seamlessly with any sensor producing a signal within the ±2000 mV range, making it suitable for both pH and ORP (Redox) measurement.

• Long-Lasting Battery Power: Powered by 4x AAA batteries, the unit is fully isolated from mains noise. Due to the ultra-low power consumption of high-impedance instrumentation, the amplifier can operate for years before replacement is needed (especially when using high-quality cells like Energizer Lithium L92).

• Robust Field Design: Enclosed in a compact IP65 rated housing, the amplifier is dust-tight and protected against water jets, making it ideal for outdoor installation or wet industrial areas.

• Enhanced Stability: By buffering the signal at the source, the system becomes significantly more resistant to electrical interference from pumps, motors, and variable frequency drives (VFDs).

Technical Specifications

Ideal Applications

This signal amplifier is the perfect solution for:

• Remote Monitoring: Connecting a pH sensor in a remote tank to a controller located in a control room hundreds of meters away.

• Noisy Environments: Stabilizing readings in plating shops, wastewater treatment plants, or factories with heavy electrical machinery.

• Retrofit Installations: Upgrading existing sensors to work with standard cabling infrastructure.
