Need to test the hardness of your water accurately?
These eXact Micro Total Hardness strips are the way to go.
Important note first: you NEED an eXact series photometer (like the eXact Micro 20, version earlier than 3) to use these.
The strips themselves don't give a visual color change you can read with your eyes.
Here's how it works: you dip the special reagent strip into the photometer's sample cell filled with your water.
This releases the exact amount of reagent needed.
The photometer then measures the resulting color/turbidity change and gives you a digital readout on its screen.
It's super simple – just dip and read on the photometer.
This bottle contains 50 test strips, and they measure total hardness in a range from 0 to 300 parts per million (ppm).
It's a professional-grade method that's way more precise than guesswork, perfect for aquarium owners, hydroponics, pool/spa maintenance, or checking your home's water quality.
Made in the USA by Industrial Test Systems with a focus on accuracy and reliability.
If you already have the compatible photometer, these strips are an essential consumable.
