Digital pH Tester Pen for Water Hydroponics – Accurate, Portable, and Easy to Use
Looking for a reliable tool to test the pH of your water? The Digital pH Tester Pen for Water Hydroponics is your go-to gadget for quick, accurate, and hassle-free pH measurements. Whether you’re into hydroponics, aquaculture, or just want to check the pH of your drinking water, this portable pH meter has got you covered.
Why Choose Our Digital pH Tester Pen?
High Accuracy & Stability: With a measurement range of 0-14 pH, a resolution of 0.01 pH, and an error margin of just ±0.1 pH, this tester gives you precise readings every time.
Portable & Durable Design: Compact at 1553118mm, it comes in vibrant colors (red, yellow, blue, orange-black) and includes a protective sleeve to keep the glass probe safe during transport.
Easy-to-Read Display: Features a large, high-definition LCD screen for clear and stable readings—no squinting needed!
Temperature Compensation: Automatically adjusts for temperatures between 0°C-50°C, ensuring accurate results even if the water isn’t at the ideal 25°C.
Long Battery Life: Powered by two 1.5V LR44 button batteries, it lasts 1-2 years with normal use.
High-Sensitivity Glass Probe: The sensitive bulb ensures fast and reliable measurements so that you can trust the data.
Automatic Temperature Compensation – No More Guesswork: The Digital pH Tester Pen comes with a super handy automatic temperature compensation feature that keeps your pH readings spot-on, no matter the temperature. We all know temperature can mess with pH values—too hot or too cold, and your readings might be off. But don’t worry! This pen adjusts for you. If the water’s too cold, it warms things up a bit; if it’s too hot, it cools things down. It always keeps the temperature in the sweet spot (between 0°C-50°C) so you get accurate results every time. Say goodbye to measurement errors caused by temperature changes—this pen’s got your back!
Perfect for Multiple Uses
This digital pH tester pen is a must-have for a wide range of applications:
Testing drinking water and household water for safety.
Monitoring pH in hydroponics, aquaculture, and agricultural settings.
Checking acidity/alkalinity in food processing or wastewater.
Conducting experiments in labs with precise pH needs.
How to Use the Digital pH Tester Pen
It’s super simple to get started:
- Remove the protective cap and rinse the electrode with distilled water. Wipe it dry with filter paper.
- Press the “ON/OFF” button to power it on, then dip the electrode into your solution. Gently shake to remove air bubbles.
- Wait for the reading to stabilize, note the pH value, and then press “ON/OFF” to turn it off.
-
Rinse the electrode with clean water and replace the cap.
How to Calibrate for Best Results
To ensure top accuracy, calibrate your pH tester:
1. Prepare 6.86, 4.00, and 9.18 standard buffer solutions and distilled water in separate clean cups. Use one cup for rinsing and another for calibration per solution.
2. Turn on the device and place the electrode in the pH 6.86 solution. Gently stir and wait for a stable reading.
3. Press the “CAL” button for 5 seconds to enter calibration mode until the display matches the standard pH value at that temperature. Repeat for pH 4.00 and 9.18 solutions as needed.
