3-in-1 pH, TDS & Temperature Digital Water Tester with Buffer Solutions
Product description
3-in-1 measurements: This handheld instrument reads pH, TDS (PPM) and temperature and shows results on a backlit LCD for clear visibility. A one-button hold function locks the current reading so you can record values after removing the probe from the sample.
Precision and sensing: The meter uses a precision algorithm chip paired with a sensitive electrode to produce quick, stable pH readings. The housing includes a protective electrode cap; the body is lightweight, pocket-sized and made to withstand regular field use.
Battery and durability: Powered by replaceable batteries designed to give long run time under normal use, the unit is intended for months of routine testing without frequent battery swaps. The casing carries an IP65 splash-resistant rating for safe operation around wet setups like tanks and grow beds.
Ease of use: The interface is straightforward—switch between pH, TDS and temperature modes, read results on the illuminated screen, and use the hold feature to freeze values. The meter also supports simple adjustment/calibration so you can maintain measurement accuracy over time.
Applications: Ideal for monitoring drinking water, aquariums, hydroponic systems, swimming pools and general laboratory checks. Its compact form makes it convenient for on-the-go testing and quick spot checks throughout the day.
Included accessories: The package includes three buffer calibration solutions (pH 4.01, pH 6.86 and pH 9.18) so you can calibrate the meter before first use and whenever needed to ensure consistent accuracy.
Pros
- Measures pH, TDS and temperature in one compact unit
- Includes three buffer solutions for calibration
- Backlit display and one-touch hold for easy readings
Cons
- Not a replacement for high-end laboratory meters
- Splash resistant but not fully submersible
- Probe quality may limit long-term precision
VerdictA compact, feature-rich tester for routine water checks—suitable for drinking water, aquariums, hydroponics, pools and basic lab work. It delivers fast pH, TDS and temperature readings, is simple to operate and comes with calibration solutions. Expect good accuracy for everyday use, long battery life, and portable convenience; advanced users may prefer higher-end probes for lab-grade demands.

John Tran 3/5
Worked but failed after battery change
Functioned fine for about three years. After replacing the batteries the display started cutting off information and backlight issues began. Still works intermittently but feels cheaply made at that point.

Beth Kraemer 4/5
Simple and durable
Well-made, easy to operate and simple to keep clean. The finish and color are nice, and it’s held up to regular use without issues.

Does exactly what I needed for my tanks
I finally swapped strips for this meter and it’s been great. It arrived pre-calibrated and also comes with calibration solutions if needed. It reads pH, temperature and PPM, the display is easy to read even in low light, and the controls are intuitive. Results have been consistently accurate for my aquariums and tap water checks.

Frustrating calibration experience — avoid
Terrible experience trying to calibrate. The instructions are unclear, the menu felt illogical, and online support seems nonexistent. After hours of trying I gave up. Not recommended if you expect straightforward setup and guidance.

Excellent for aquarium pH monitoring
Helped stabilize my daughter’s tank after unreliable test strips caused problems. The pH readings are consistently reliable and it’s easy to test multiple times a day. Temperature and TDS have been less trustworthy for us, but the pH performance is outstanding and batteries have lasted months.

Dependable when cared for
I’ve owned two of these over time and both performed well out of the box without needing recalibration. Treat it like a precision tool—keep it dry, clean and stored—and it will last. I’d buy it again.

Good value and repairable probe
Solid budget tester with pH, TDS and temp in one unit. A nice bonus is the probe can be replaced using a pin-style connector similar to higher-end models, so you can upgrade the sensor later instead of discarding the whole meter. Looks and functions above its price point.

Useful for quick water checks
Good tool to quickly assess tap water and decide on filtration needs. Two temperature units are available (°C/°F) via a long press. Temperature has been accurate for me, and after a couple months this unit feels well made.
