-
The ETI pH PAL Plus pH Tester is your essential tool for ensuring accurate water quality measurements across a range of applications, from hydroponics and gardening to brewing and food processing. This high-specification, pocket-sized digital pH meter is designed for maximum reliability and effortless use, providing dependable readings from 0 to 14 pH with minimal maintenance. It is the ideal device for professionals and hobbyists who require fast, precise, and user-friendly pH management.
Key Benefits of the ETI pH PAL Plus
- Effortless Accuracy: Features one-touch automatic calibration using pH 7.00 buffer solution (pH Buffer) for hassle-free, reliable results with an accuracy of ±0.2 pH.
- Highly Portable Design: The durable, pocket-sized casing (70 grams) is water resistant and easy to carry, making on-the-go water testing simple and immediate.
- Full Range Measurement: Capable of measuring the entire pH range from 0 to 14, suitable for all nutrient solutions and liquid samples.
- Extended Battery Life: Provides approximately 150 hours of continuous use, supported by an auto-power off function after 10 minutes to conserve battery life.
- Convenient Data Hold: A useful 'Hold' function freezes the current reading on the 8mm LCD display, allowing you to easily record results without rushing.
How to Use the ETI pH PAL Plus
The ETI pH PAL Plus is designed for simplicity. For best results, follow these steps:
- Preparation: Remove the protective cap. Before the first use and between calibrations, rinse the electrode tip gently with distilled water or de-ionised water.
- Calibration: Calibrate the unit regularly (daily or weekly, depending on use) for optimum accuracy. Dip the electrode into a fresh pH 7.00 buffer solution. Press the calibration button, and the meter will automatically adjust itself. For increased accuracy, a two-point calibration may be performed using pH 4.01 or pH 10.01 buffers as well (check the instruction manual for your specific unit's full calibration procedure).
- Measurement: Dip the electrode into the liquid sample (such as your hydroponic nutrient tank or soil slurry) and gently stir. Wait a few moments for the reading to stabilise on the LCD screen.
- Storage: After use, rinse the electrode with distilled water and blot dry with a lint-free cloth. Always store the electrode tip hydrated, ideally in a specialised pH Electrode Storage Solution within the protective cap.

Frequently Asked Questions
Why is regular calibration necessary for pH meters?
The sensor's measuring characteristics naturally shift over time. Calibration allows the ETI pH PAL Plus to correct for this drift by measuring a known buffer solution (like pH 7.00), ensuring the readings remain accurate and reliable for critical applications like nutrient solution testing.How often should I calibrate my pocket pH meter for hydroponics use?
For high-accuracy environments like hydroponics, where stable nutrient pH is critical for plant health, daily or weekly calibration is generally recommended. If you notice unstable or drifting readings, re-calibrate immediately before use.How should I store the pH electrode to prolong its life?
Always keep the glass electrode bulb hydrated. The best method is to store the probe cap with a few drops of specialised pH Electrode Storage Solution like Growth Technology pH Probe Refill & Storage. Never store the probe dry or in distilled/de-ionised water for long periods, as this can deplete the electrolyte solution and damage the sensor.Why can’t I wipe down a pH electrode?
Wiping the delicate glass pH electrode can damage the sensitive hydrated gel layer and may generate a static charge, which can potentially interfere with the accuracy of the pH measurement. Instead, gently rinse the electrode with distilled water and blot away excess moisture with a lint-free paper towel.SKU: 1122 - Automatic calibration feature
