Choosing the Right Meter

Find the water parameter you wish to measure, and you'll find the most popular Myron L meter for that parameter.  

Note: testing more than one parameter will require a multiparameter meter like the Ultrameter.

Measuring DS (Dissolved Solids) or TDS (Total Dissolved Solids)

Total Dissolved Solids (often abbreviated TDS) is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form. Generally the operational definition is that the solids must be small enough to survive filtration through a filter with two-micrometer (nominal size, or smaller) pores.

Measuring Conductivity or EC (Electrical Conductivity)

The conductivity (or specific conductance) of water is a measure of its ability to conduct electricity.

Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of measuring the ionic content in a solution. For example, the measurement of product conductivity is a typical way to monitor and continuously trend the performance of water purification systems.

Measuring Salinity

Salinity is the saltiness or dissolved salt content (such as sodium chloride, magnesium and calcium sulfates, and bicarbonates) of a body of water or in soil.

Measuring pH

pH is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7.

Measuring Resistivity

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly water opposes the flow of electric current.

Measuring ORP (Oxidation Reduction Potential)

In water, the reduction potential is a measure of the tendency of the solution to either gain or lose electrons when it is subject to change by introduction of a new material. A solution with a higher (more positive) reduction potential than the new material will have a tendency to gain electrons from the new material (i.e. to be reduced by oxidizing the new material) and a solution with a lower (more negative) reduction potential will have a tendency to lose electrons to the new material (i.e. to be oxidized by reducing the new material).

Measuring Free Chlorine

Myron L meters report FAC (free available chlorine) quickly and accurately by measuring ORP, the chemical characteristic of chlorine that directly reflects its effectivity, cross referenced with pH.

Measuring LSI (Langelier Saturation Index), Water Hardness, Alkalinity

LSI: Langelier Saturation Index (sometimes Langelier Stability Index) is a calculated number used to predict the calcium carbonate stability of water.

Water's hardness is determined by mineral content or concentration of multivalent cations in the water.

Alkalinity is the name given to the quantitative capacity of water to neutralize an acid. Measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater. It is one of the best measures of the sensitivity of the stream to acid inputs.
