| Chlorine & Fluoride Meters Measure total chlorine or fluoride quickly, economically and accurately. Useful in any processes that use chlorine as a biocide and sanitation agent such as industrial process water, spas, pools and food processing. | 
| Colorimeters Measure Chlorine, pH, and Cyanuric acid with Oakton multifunction Colorimeters. Ideal for pool & spa use, and monitoring water quality of drinking water or wastewater applications. | 
| Conductivity Meters Use these meters for testing hard water, untreated water, cooling tower water, wastewater, rinse tanks, ponds and more. | 
| Dissolved Oxygen Meters Measure Dissolved Oxygen for water pollution studies and at waste water treatment facilities, aquaculture (fish farming), surface and ground water surveys, and evaluating the safety of potable water. | 
| ORP Meters Easy to use meters for testing oxidation-reduction (REDOX) potential. Ideal for water treatment applications, aquarium monitoring and water pollution monitoring. | 
| pH Meters Measure pH of food, beer, wine, milk, rinse water, wastewater and more. Need to measure pH in solid or semi-solids? The Extech PH100 with a flat surface electrode provides on the spot pH measurements. | 
| Salinity Meters Check salt levels in brines, pool water, and aquaculture systems. | 
| Water Quality Meter Kits View a variety of kits allowing you to measure Chlorine, pH, ORP, Salinity, TDS, and Dissolved Oxygen. A great value when compared to buying individual meters for measuring water quality. |
