The CS-LH-PH-025 Hydroponic pH Meter provides potentiometric pH measurement for aquatic systems, hydroponics, and general laboratory applications. This digital meter features a detachable electrode design that facilitates electrode replacement and maintenance workflows. The unit operates across a temperature range of 0-45°C and offers dual power options including battery operation (4×1.5V AG13) or AC adapter (220V) for continuous monitoring applications.
The meter's aquarium-compatible design makes it suitable for monitoring pH in controlled aquatic environments, nutrient solutions, and water quality testing protocols. The detachable electrode configuration allows researchers to select appropriate electrode types for specific measurement conditions and replace electrodes as needed to maintain measurement reliability.
How It Works
The CS-LH-PH-025 operates on potentiometric measurement principles, utilizing a pH-sensitive electrode to generate a voltage potential proportional to hydrogen ion activity in solution. The electrode system typically consists of a glass membrane electrode sensitive to H+ ions and a reference electrode that provides a stable potential. When immersed in solution, the pH electrode develops a potential difference that correlates with the pH value according to the Nernst equation.
The digital display converts the electrode potential into pH units through internal signal conditioning and calibration algorithms. The detachable electrode design allows the measurement system to be optimized for different sample types by selecting appropriate electrode configurations. Temperature compensation may be incorporated to account for the temperature dependence of pH measurements in the 0-45°C operating range.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Electrode Configuration | Detachable electrode system | Many entry-level meters feature fixed electrodes | Enables electrode replacement and selection of specialized electrodes for different sample types. |
| Power Supply Options | Dual power (4×1.5V AG13 or AC 220V) | Single power source designs are common | Provides flexibility for both portable and continuous monitoring applications. |
| Operating Temperature | 0-45°C operating range | Temperature ranges vary by model | Covers typical laboratory and controlled environment temperature conditions. |
| Application Focus | Aquarium-compatible design | General-purpose pH meters without aquatic optimization | Specifically designed for aquatic research and hydroponic applications. |
The CS-LH-PH-025 offers detachable electrode flexibility and dual power options in an aquarium-compatible design. The 0-45°C operating range and specialized aquatic application focus distinguish it from general-purpose pH meters.
Practical Tips
Calibrate using buffers at the same temperature as your samples when working in the 0-45°C range.
Why: Temperature affects both electrode response and buffer pH values.
Store the detachable electrode in appropriate storage solution between measurements.
Why: Proper storage prevents electrode dehydration and maintains measurement stability.
Rinse the electrode with distilled water between samples to prevent cross-contamination.
Why: Sample carryover can affect measurement accuracy, especially with different ionic strength solutions.
Check electrode connection if readings appear unstable or drift excessively.
Why: Loose connections in detachable electrode systems can cause measurement instability.
Allow readings to stabilize before recording values, especially in temperature-variable environments.
Why: Thermal equilibration affects both electrode response and sample pH.
Use AC adapter only in dry laboratory environments away from water sources.
Why: Electrical safety is critical when combining AC power with aqueous measurements.
