What is Sulfate?

Sulfate is present at widely varying conditions in natural waters. Sulfate levels are monitored in the beverage industry as well as in cooling water and ion exchange systems in order to prevent calcium sulfate scale formation.

Sulfate Exposure and Health Risks

Increased concentration of sulfate in water will cause it to have a salty taste and odor. Sulfate ions act as an osmotic laxative. Increased exposure to sulfate will increase large intestinal motility and inhibit large intestine fluid/electrolyte absorption.

Measuring Sulfate

Dissolved Sulfate concentration in water can be measured in units of parts per million (ppm). We carry an instrumental kit from CHEMetrics that determines Sulfate levels in water. All of our Sulfate products can be viewed HERE.

The Sulfate Kits are designed to accurately measure sulfate levels in water using the Turbidimetric Method.

The K-9203 Sulfate Vacu-vials Kit is used to measure sulfate levels from 0-100 ppm.
