Start Analog pH Monitoring with a Simple Ready-to-Use Kit
The Atlas Scientific Surveyor Analog pH Kit is a low-cost analog pH sensing kit built for quick integration and easy setup. It combines the Surveyor™ Analog pH Sensor / Meter with a consumer grade pH probe and the buffer solutions needed to get started.
This kit is a good fit when you want a basic analog output instead of a full digital EZO setup, while still using Atlas Scientific sensing hardware.
Important: This product was previously known as the Gravity Analog pH Kit. It is intended for analog pH monitoring and includes the core probe and calibration items needed to begin.
Why you'll love it
- Simple analog output: Good for projects that prefer a direct analog pH signal
- Complete starter bundle: Meter, probe, and pH 4, 7, and 10 pouches are included
- Low-cost option: A practical entry point for basic pH monitoring
- Compact board: Small format helps with compact prototypes and test rigs
- Useful for many liquids: Suitable for general pH checks in DIY and engineering builds
What you can build
Use it for small lab rigs, educational builds, hydroponics projects, aquarium checks, soil and water experiments, and simple controller systems that need analog pH data.
Starter bundles
Pair it with an Arduino-compatible controller, analog input board, display, or simple logger. A probe holder and storage solution can also help with daily use.
Recommended add-ons
Helpful add-ons include extra pH calibration pouches, probe storage solution, replacement probes, isolators, and panel mounts for cleaner installs.
