Precision 4-in-1 Hydroponic Water Tester — pH, TDS, EC & Temp (Titanium Probe)

If you’ve made the switch to semi-hydroponics—whether it’s Leca, Pon, or full water culture—you know that the “eyeball method” for nutrients is a recipe for root burn. This 4-in-1 digital tester removes the guesswork by giving you an instant, laboratory-accurate reading of your pH, TDS, EC, and temperature.
Built with a high-precision titanium alloy probe, it’s designed to handle the mineral-heavy environments of nutrient solutions without rusting or losing calibration as fast as cheaper alternatives. It’s the difference between “hoping” your plants are okay and actually knowing they have the perfect environment to thrive.
Precision Nutrient Management
For high-value houseplants, water quality isn’t just about “wet or dry.” It’s about chemical balance. This 4-in-1 tester is the gold standard for home growers, providing four critical data points in a single 5-second dip.
Ensure your nutrients are actually bio-available. Most houseplants need a pH of 5.5 to 6.5 to “eat.”
Measure exactly how much fertilizer is in your water. No more guessing if your solution is too “hot.”
Why it’s better for collectors:
- Titanium Alloy Probe: Unlike standard sensors, titanium resists corrosion from salts and minerals in hydroponic fertilizers.
- Automatic Temperature Compensation (ATC): Water chemistry changes with heat. This pen adjusts automatically for accuracy between 0-60°C.
- High-Definition Backlit Display: Clear green lighting makes it easy to read in grow tents or dimly lit corners.
- Data Hold Function: Press “Hold” to lock the reading before pulling it out of the water.
Setup & Calibration
Calibration is the most important step for accuracy. We include three buffer powder packets (4.01, 6.86, and 9.18 pH) to get you started.
- Prepare the Solution: Dissolve each packet into exactly 250ml of distilled or deionized water. Label your containers. Properly sealed, these solutions last up to 1 year at room temperature.
- Calibrate: Turn the meter on, dip into the 6.86 solution, and hold the "CAL" button for 5 seconds. Repeat for other levels if needed.
- Testing: Remove the protective cap, rinse the probe with distilled water, and dip into your nutrient reservoir. Stir gently and wait for the reading to stabilize.
- Cleaning: After every single use, rinse the probe with distilled water and gently pat dry with a clean tissue.
Can I use this to test soil pH?
No. This is a liquid tester designed for water and nutrient solutions. To test soil, you must mix a soil sample with distilled water, let it sit for 30 minutes, and then test the liquid "slurry."
How often do I need to calibrate it?
If you use it daily for your hydroponics, we recommend calibrating once a month. If you only use it occasionally, calibrate it before any major nutrient change.
Why do I need distilled water for calibration?
Tap water contains minerals that will mess up the chemistry of the calibration powders. For a true 6.86 pH reading, the base water must be less than 10.00 ppm (Distilled or Deionized).
What happens if I don't rinse the probe?
Fertilizer salts will dry on the titanium sensor, creating a crust that slows down the reading time and eventually degrades the accuracy. A 2-second rinse after every use prevents this.

6-in-1 Intelligent Soil & Environment Detector — pH, EC Fertility, Moisture, Temperature, Sunlight & Air Humidity with Backlit LCD Display
A digital 6-in-1 soil and environment meter that reads six parameters simultaneously from a single insertion: soil electrical conductivity (EC/fertility), moisture level, pH, temperature, ambient light intensity (LUX), and air humidity. All six values appear at once on a backlit green LCD screen, so you can assess your plant's growing conditions in under 10 seconds without switching modes or swapping probes.
pH range 3.5–9.0 pH (resolution 0.1 pH); moisture 0–99%; EC fertility 0–1999 μS/cm; temperature in °C or °F; sunlight 0–13,500+ LUX; air humidity 0–99%. Powered by 2× AAA 1.5V batteries. Foldable rotatable screen.
pH Test Strips — pH 1–14, 80 Strips, for Soil, Fertiliser & Hydroponics
A pack of 80 pH test strips covering the full pH 1–14 range. Dip a strip into your soil solution, fertiliser mix, compost tea, or hydroponic reservoir — the paper changes colour in 2 to 3 seconds, and you match it against the included colour chart to read the pH value.
Each strip measures 5.3 × 1.0 cm and reads across the full acid-to-alkaline spectrum in a single dip. Accuracy is ±1 pH unit — sufficient for monitoring soil and fertiliser pH in home and hobbyist growing situations where you need to know whether your pH is in range, not a laboratory-precise decimal point. 80 strips per pack.
