e-Sens Autonomous Water Testing

Know Your Water. Simplify Your Day.

23 Parameters. One Sample. Smarter Water Testing.

Take the complexity out of water testing with e-Sens. This innovative water analyzer simplifies sampling, testing, and reporting, giving you accurate, reliable water quality information with less hands-on work.

Available as a portable handheld device or an automated inline analyzer, e-Sens helps you stay ahead of changing water conditions and make informed decisions.

Two Ways to Test

Handheld e-Sens: Powerful Testing. Anywhere You Need It.

Simplify routine water testing with a portable device that provides comprehensive water chemistry results from a single sample.

Convenient, on-demand testing
Up to 23 parameters from one sample
Less time spent performing individual tests
Easy access to water quality information

Inline e-Sens: Automated Testing. Greater Visibility.

Connected directly to your process line with a simple quick-connect fitting, the inline e-Sens automatically samples, tests, and reports water quality results.

Automated sampling and testing
Consistent results at scheduled intervals
Automatic reporting and remote access
Less manual testing and recordkeeping

Testing That Runs Itself (Give Hours Back to Your Maintenance Team)

Samples, tests, and reports on a set schedule so your maintenance and operations staff stay focused on production.

Problems Surface Before They Shut You Down

Frequent automated testing catches drift toward scale, corrosion, or microbiological growth well before the next manual test would. Out-of-range results send an alerts so corrective action starts before equipment fails.

Same Result, Whoever is on Shift

Every test uses the same method. Vacancies, turnover, and new hires no longer change the quality of your water data, and no one has to be trained on test kits.

Peace of Mind

Provides precise test data, delivering reliable results.

Flexible Testing for Your Application

Choose from specialized testing cartridges designed for your water treatment needs:

23 Full List: Comprehensive water quality analysis covering all 23 parameters.
Disinfection: Focused on chlorine, monochloramine, and other disinfection parameters.
Cooling Tower: Targeted parameters important for scale, corrosion, and microbial control.
