U.S. Made Amperometric Chlorine Analyzers, Online Analytical Instruments, Toxic Gas Detectors

Making instruments to simplify water monitoring backed by customer service that is second to none.

Integrity

Whether you're producing drinking water, a food or beverage, or treating wastewater, your finished product is critical to public safety, the environment and your reputation.

You can't tolerate poor performance, frequent maintenance and repairs, or high cost of ownership.

Accordingly, we won't cut corners to boost profits or to match the lowest price in building our chlorine and other online water analyzers.

User Friendly

It doesn't matter how well you design or build a product, or how well it can work, if the end user has difficulty using it.

One of our priorities is ease of use so that the instrument performs as designed when used by ordinary people without extensive training in process instrumentation or costly service contracts.

Testing

We wet test or gas test every instrument thoroughly before shipment to ensure it works as expected.

Testing by 4-20mA input signal simulation is not a valid test of the instrument's functionality.

Integrity

If a product won't work well for long periods of time we simply won't build, offer or sell it.

You don't stay in business since 1963 by working any other way.

Experience & Service

For those seeking quality, trouble-free operation and honest advice, we have over 55 years of experience in chlorine measurement and control.

We try to provide unmatched personalized service to support you.

Chlorine and Disinfectant Monitoring and Control

Our amperometric chlorine analyzers are used to control disinfectant chemical feed in drinking or wastewater, industrial process water and to monitor the drinking water distribution system.

We make two basic types that are applied based on water quality rather taking a one size fits all approach.

Models include bare electrode chlorine analyzers that work in virtually any water quality and reagentless chlorine and chlorine dioxide probe based systems for clean water.

None of our analyzers are intended to verify chlorine removal or zero chlorine discharge to the environment.

Given our customers' regulatory requirements, our team returns repairs within 1-2 days, sometimes the same day, without charging a premium for expedited service.

We believe our products, expertise and service has been integral to our earning long term and word of mouth customers.

Design & Build To Last

We design by anticipating common mistakes and less than careful use.
We use materials and components that can withstand daily use year in and year out.
It doesn't cost much more to do the job right; it gives us pride in our workmanship as well as a lower cost of ownership with less frustration to our customers.

Assume Nothing

Despite decades of experience in manufacturing and assembly, we don't assume a product will work.
Every instrument is tested under real world conditions before it can ship: chlorine analyzers run a minimum 4 to 6 hours with water and are verified with an amperometric titrator, detectors must respond to a certified target gas.

We Take Responsibility For Our Work

Most of us who've had a defective product or problem have experienced a customer service rep who assumes you must have damaged or abused their product for it to malfunction.
Rather than assigning blame, we focus on problem solving and resolution; and do whatever it takes to make it work or make it right.
