Industrial-Grade Durability

The industrial pH probe supports 24/7 continuous measurement and offers a lifespan exceeding 4380 hours. Its rugged design ensures reliable performance in harsh or long-term monitoring scenarios.

 

High Accuracy & Auto Calibration

With a measurement accuracy of ±0.1 pH at 25°C, this kit uses a two-point calibration method. The included software library can automatically identify standard buffer solutions (pH 4.0 and 7.0), simplifying the calibration process while maintaining precision.

 

Wide Compatibility & Easy Integration

The system operates on a 3.3V to 5.5V input range, making it fully compatible with Arduino, Raspberry Pi, LattePanda, and other popular microcontroller platforms. The Gravity interface and BNC connector allow for a plug-and-play setup—no soldering required.

 

Features

  • Wide voltage input (3.3~5.5V) for broad microcontroller support

  • Hardware-filtered analog output, reducing noise and signal jitter

  • Two-point calibration with automatic buffer recognition

  • Gravity + BNC connectors, plug-and-play design

  • Industrial-grade pH probe for 24/7 monitoring

  • Upgraded transmitter board for enhanced stability and precision

  • Standardized dimensions and connectors for easier hardware integration

Usage Notes

  1. Keep the BNC connector and signal board dry and clean to prevent impedance issues.

  2. Avoid placing the board on wet surfaces; use nylon spacers for safe mounting.

  3. Do not allow the probe tip's glass bulb to contact hard materials.

  4. Disconnect the probe after use if the system is powered off for long durations.

  5. White crystals may form around the probe cap due to protective KCL solution; this is normal and does not affect performance.
