Feed with confidence.
Check pH and EC before nutrients reach your plants. Get a clearer picture of the solution you're mixing.
A clearer way to care for what grows.
Know your water.
Change everything.
Before you feed your plants, welcome friends to the pool, or add another fish, take a reading. Five essential measurements. One meter. A better next move.

A little knowledge changes the outcome
The water looks fine.
But what does it say?
Guessing is easy. A real reading lets you adjust the nutrient mix, check a saltwater system, or see how your RO filter is performing.
Check before the first splash.
Read pH, salinity and temperature when caring for a saltwater pool. Use proper pool tests for chlorine and other required chemistry.
Know before they go in.
Measure pH, salinity, and temperature as part of your aquarium routine before introducing new fish.
See what your filter is doing.
Compare TDS readings before and after an RO system and track changes over time. TDS alone does not establish drinking-water safety.

From people who use it
Real routines. Real confidence.
★★★★★“I just love this meter. It’s accurate across ph, ec, ppm, and temperature. It’s easy to use and just reliable.”
★★★★★“Purchased this meter as I was tired of wondering if the salt ppm levels were correct on my chlorine generator setting.”
★★★★★“We primarily use a TDS meter to test our filtered drinking water, so we know when it is time to change the filter cartridges in our R.O. water filtration system.”

Good to know
Every detail matters.
What does the meter measure?
pH, electrical conductivity (EC), total dissolved solids (TDS), salinity, and temperature. These readings serve different purposes; choose the one appropriate to your water and use.
Can I use it for drinking water?
You can compare TDS readings to monitor an RO system. TDS is not a drinking-water safety test and cannot identify specific contaminants. Use certified lab testing when you need to assess safety.
Can it replace my pool test kit?
No. The meter can help you check pH, salinity, and temperature, but it does not measure chlorine, stabilizer, alkalinity, or other parameters your pool may require.
What comes in the box?
The product listing includes the meter, a protective cap, and calibration solution. We can confirm the exact calibration solution and other accessories with our team before you order.
