How To Use
How To Use
Step 1: Turn On The Meter
Press the ON/OFF button to power on the tester.
Step 2: Immerse The Probe
Remove the cap and place the probe into the water sample. Stir gently for a stable reading.
Step 3: Read The Locked Value
Wait a few seconds until the reading stabilizes and auto-locks on the LCD screen.
Step 4: Rinse & Store
After testing, rinse the probe with clean water, dry it gently, and store it in the protective case.
TDS shows the approximate concentration of dissolved solids in water, usually displayed in ppm. It is often used for checking filtered water, RO systems, bottled water, tap water, and general water quality reference.
EC measures the water’s electrical conductivity, which can be useful for hydroponics, aquaculture, nutrient solutions, and water treatment reference.
Temperature reading helps you understand the testing environment and supports more consistent interpretation when comparing water samples.
Test Water Faster. Read Results Clearer. Make Better Water Decisions.
Whether you are checking tap water, filtered water, RO systems, aquariums, hydroponics, or pool water, this 3-in-1 digital tester gives you quick TDS, EC, and temperature reference readings in one compact, professional-feeling tool.
Professional 3-in-1 Testing In A Pocket-Size Meter
Instead of using separate tools for each measurement, this digital tester combines TDS, EC, and Temperature into one ergonomic pen-style meter. Whether you are checking household drinking water, filtered water, bottled water, well water, aquarium water, hydroponic nutrient solution, or pool water, it gives you quick reference data in seconds.
Read Faster. Record Easier. Test With More Confidence.
Stable Readings For Everyday Water Decisions
The titanium alloy probe and intelligent chip are designed to support stable signal detection, while Automatic Temperature Compensation (ATC) helps adjust readings based on water temperature. The tester also includes a color reference chart on the back, making it easier to understand ppm ranges at a glance.

-
“Great for checking my filter.”
I use it before and after my countertop filter just to see the difference in TDS. The auto-lock makes it easy to write the numbers down.
-
“The screen is much easier to read.”
I had an older tester without a backlight, and it was annoying in my utility room. This display is clearer and faster to use.
-
“Good hydroponic reference tool.”
I use it for my nutrient solution. The EC and temperature readings are helpful when I am adjusting my setup.
Questions From Our Customers
What does this tester measure?
What does this tester measure?
It measures TDS, EC, and water temperature.
What is TDS?
What is TDS?
TDS means Total Dissolved Solids. It gives a reference value for dissolved minerals, salts, and other solids in water.
Does low TDS mean the water is safe to drink?
Does low TDS mean the water is safe to drink?
Not necessarily. TDS does not test bacteria, viruses, heavy metals, pesticides, or specific contaminants. Use certified lab testing for safety concerns.
Do I need to calibrate it myself?
Do I need to calibrate it myself?
The tester is factory calibrated and ready to use. For high-precision professional work, follow calibration guidance from the product manual if provided.
Can it test RO filter performance?
Can it test RO filter performance?
Yes, it can help compare TDS before and after filtration as a general reference for RO or filter performance.
Can I use it for aquariums?
Can I use it for aquariums?
Yes. It can be used as a reference tool for aquarium water maintenance. Always follow the specific requirements of your fish or aquatic plants.
Can I use it for hydroponics?
Can I use it for hydroponics?
Yes. TDS and EC readings are commonly used as reference values in hydroponic nutrient management.
How do I clean the probe?
How do I clean the probe?
Rinse the probe with clean water after each use and dry it gently before storing.
Why do readings change with temperature?
Why do readings change with temperature?
Water temperature can affect conductivity-related readings. ATC helps compensate for temperature changes.
Does it turn off automatically?
Does it turn off automatically?
Yes. It includes an auto-off function after about 2 minutes of inactivity to help conserve battery.
