Test for contaminants before installing water-treatment equipment such as boilers and filters. You can also check your pipes and equipment for improper chemical levels that can cause corrosion and scale buildup, shortening their life.

Check pH levels without a meter. When this testing paper is dipped in a sample, it changes color to indicate pH.

Don’t strain your eyes reading a scale—these bench-top meters indicate exact results on the digital display.

Test temperature, chemical concentration, contamination, and salt levels in liquid from up to 6 ft. away, then send the results to your computer for analysis.

Check pH in harsh field conditions. These floating meters that have a housing that meets IP67 for complete resistance to dust and protection from temporary submersion.

Transmit pH readings to a PC for analysis. These meters have a sensor on a 6-ft. cable for taking remote readings of water and other clean liquids.

Pour contaminated water, wastewater, printing fountain solutions, and other dirty liquids into the meter cup to test electrical conductivity levels that indicate the concentration of salts, nutrients, chemicals, and other substances.

Since these meters float and have a housing that meets IP67, they won’t be damaged by temporary submersion and have complete resistance to dust. They detect total dissolved solids (TDS) in water, hydroponic solutions, and other clean liquids to determine contaminant levels.

Since this oxidation reduction potential (ORP) meter has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion, it’s often used to determine a solution’s ability to break down contaminants in harsh field conditions.

A bayonet connection makes these sensors compatible with most chemistry meters and controllers.
