Technicians, scientists and water treatment operators measure water hardness parts per million (ppm) or grains per gallon (gpg). Converting ppm to gpg is simple, but requires a calculator. Enter the water hardness value, in parts per million, into the calculator. Double-check the entry to ...
A TDS meter is an instrument used to measure the total dissolved solids (TDS) in any given sample of water. It measures the electrical conductivity (EC) of the water, which is then measured in parts per million (ppm). TDS meters are used to measure the purity of drinking water. In mos...

How To Measure Ozone Levels In Water? Ozone in water can be measured using a manual ozone test kit or ozone meter. Ozone is measured in ppm (parts per million), and it is easily correlated to the mV (millivolts) reading on an ORP (oxidation-reduction potential) meter to provide you ...
A TDS meter is a tool used to measure ppm. Technically, you measure the TDS of water, and you measure it in ppm. However, most people just skip over TDS and use ppm for both terms. There are many TDS meters of varying cost and abilities; some also measure temperature or have hold ...
No, water hardness is most often measured in parts per million (ppm) or grains per gallon (gpg). But let’s not jump ahead! First, a refresher on hard water and what it can mean for your home. What Is Hard Water? You want the water coming out of your tap to be refreshing, ...
These calculators require inputting the same type of quantity (either volume or mass) providing you with accurate results. It is important to note that a measure of milligrams per liter (mg/L) of water is also considered a ppm amount by mass, given that 1 liter of water has a mass ...
If you start getting in the range greater than 1000 mg/L, this starts breaking down. If you want the true conversion, you have to measure the density of the solution. Remember 1 ppm = 1 mg/kg, so [1 mg/kg] × [kg/L (density)] = mg/L ...
Are lower TDS water levels harmful to health? TDS is not a measure of one single contaminant but in general of many cations and anions. The TDS levels are usually regulated by government bodies and can differ depending upon the place and the people's lifestyles. High TDS levels can affect ...
How to Measure Water Hardness: how many grains of hardness is found in your water? Definition of hard water As we explain in more detail at WATER SOFTENERS & CONDITIONERS, Water "hardness" refers to the level of unwanted minerals, principally calcium and magnesium, found in your water supply...
