JOVIA PH Pen Digital Water Quality Analyzer 0.01 High Precision 0-14 Measurement Range Large Backlit LCD Display Portable Tester Drinking Water Pool Aquarium Hydroponics Laboratory Uses

• 【High Accuracy PH Testing】This digital pH meter boasts an accuracy within ±0.1 pH, ensuring reliable readings within seconds whether you're testing the alkalinity of drinking water, checking pool water balance, or monitoring the pH of hydroponic plant nutrient solutions. Simply press the power button and immerse the electrode in the liquid for quick results.
• 【Led Backlit Screen For Dark Environments】Unlike standard pH testers with small, hard-to-read displays, our portable pH pen features an LED backlit screen that illuminates clearly even in dim lighting conditions. Use it in your basement aquarium room, check water quality in a dimly lit laboratory, or test your pool water in the evening after work.
• 【Automatic Calibration For Consistent Results】Maintaining calibration accuracy is essential for reliable pH testing. This pH meter features an automatic calibration function with a simple one-point or two-point calibration process using standard buffer solutions. When the reading drifts over time, you can recalibrate the device in minutes to restore its accuracy.
• 【One Key Operation With Fast Response】Designed with simplicity in mind, this digital pH tester requires just a single button to operate. Press the button to power on, dip the probe into your liquid sample, and within seconds the stable pH reading appears on the LED screen. The auto power-off feature turns off the device after a period of inactivity to conserve battery life.
• 【Wide Applications For Home And Industrial Use】This versatile pH testing pen is suitable for a broad range of applications. In the home, use it to test drinking water, aquarium and fish tank water, swimming pool and hot tub water, and water for houseplants. For hobbyists, it is essential for hydroponic nutrient solution management, kombucha and wine brewing, and soil slurry testing.

Key Features LED Backlit Screen – Bright digital display ensures easy reading in both bright sunlight and dim environments Portable Design – Pocket-sized and lightweight for easy carrying and storage Product Specifications Brand JOVIA Measuring Range 0.00 – 14.00 pH Resolution 0.1 pH Accuracy ±0.1 pH Calibration Automatic, one-point or two-point Display LED screen with backlight Power Source Battery operated Auto Power Off Yes Ideal For Drinking water, pools, aquariums, hydroponics, lab testing, industrial use How to Use Calibrate – Before first use, calibrate the pH pen using standard buffer solutions . Follow the calibration instructions provided in the user manual. Test – Press the power button, remove the protective cap, and dip the electrode into the liquid sample. Wait a few seconds for the reading to stabilize. Read – The pH value will appear on the LED backlit screen. Clean – Rinse the electrode with distilled water after each use and replace the protective cap. Do not let the electrode dry out. Care & Maintenance Tips Always rinse the electrode with distilled water before and after each use Keep the protective cap moist with storage solution or calibration buffer when not in use Recalibrate the device regularly (every 2-4 weeks depending on frequency of use) for consistent accuracy Avoid dropping the device or exposing it to extreme temperatures Replace batteries when the display becomes dim or the device fails to power on Important Notes: Do not use the pH meter for testing extremely viscous liquids or organic solvents Always handle the electrode with care – the glass bulb sensor is delicate and easily damaged If the electrode is damaged, the device will not provide accurate readings
