Waltron is one of the world's oldest, most experienced companies in the water industry. The company now integrates a variety of technologies into a comprehensive line of electronic analyzers for the Power Generation, Petrochemical, Pulp and Paper, Drinking Water, Semiconductor, and Environmental industries.

Founded in 1903 by chemists Irving Bull and Alfred Roberts, Waltron has a long history of expertise in water chemistry management. The company started as an analytical and consulting laboratory in lower Manhattan in New York City – a perfect location to sample, analyze, and make recommendations for the boiler water of the many steamships that are called in to the major seaport there. In fact, our company pioneered the first modern boiler water treatment program, including the first nuclear water chemistry program on a commercial ship, and at one point had nearly half of the US merchant fleet under contract.

Our expertise in drinking water also goes back to the original company, which introduced drinking water chlorination before the first American city-wide chlorination system was installed. Since then, we have been at the forefront of many related innovations, including the first successful chemical treatment of large land-based desalination plants, the first ultraviolet drinking water purifiers accepted by the US Public Health Service, the first widely used oil pollution monitor, and potable water chlorinators for military field applications.
Today, Waltron is a customer-focused organization dedicated to manufacture the highest-quality, lowest total cost of ownership line of instrumentation for the water quality industry.

As Water Chemistry Experts, we show our commitment and dedication every day through the quality of our relationships with our Suppliers, with our Representatives, and most importantly, with our Customers. We strive to provide the most relevant water chemistry solutions for today’s concerns.

  • Do You Really Want Manual Calibration?
    Do You Really Want Manual Calibration?

    Many of us who have been around the water industry for a while can recall the days of manually calibrating online analyzers.  The arsenal would include:  a cart of tools, calibration standard, “calibrators”, and “zero sources”.  These tools would only be used a few times a year, if that.  Although the calibration of water analysis instruments should be performed on a monthly basis, most operators would admit to only calibrating them once or twice a year. 

  • What Lies Within… What You Need To Know About Hardness Monitoring
    What Lies Within… What You Need To Know About Hardness Monitoring

    Water hardness can wreak havoc on your boilers, creating holes in tubes, eating away at the walls. To keep the hardness at bay, you’re going to need to monitor the levels of calcium and magnesium seeping into your system.  There are things you need to know to ensure that you are doing this properly. First, use an automated system to increase reaction time to hardness. Next, monitor the softeners; they are critical in keeping the system functioning. Last, learn the temperament of your individual boiler; no two are alike.  

  • Is Manual Calibration The Right Choice For You?
    Is Manual Calibration The Right Choice For You?

    When selecting a new analyzer for your plant, there are many different features to consider. One of those is the choice of how the instrument will be calibrated, namely between an inexpensive manual calibration and a more complex automatic calibration method. (To be clear, we will define automatic calibration as a feature that involves no operator intervention at the instrument.) Factors that influence this choice are financial, process, staff levels, and personal preference. Let’s explore each of those.

    Relating PLM Principles To Water Quality Management

    Regardless of whether your business is centered on a product or a service, controlling innovation and quality is a critical task for every professionally led organization. In the case of water quality management, the maintenance of documentation, process control, and measurement of results are not just important for efficiency, they are often mandated by regulations. For instrument manufacturers, they are the basic foundation of quality.

  • You Are What You Eat
    You Are What You Eat

    Behind every super-accurate instrument is chemistry that relies on near-perfection to work. In the case of colorimetric instruments commonly used to analyze water for specific impurities, this often involves multiple reagents made from high purity chemicals designed to react within specified times and precise concentrations. If any element does not work, the entire process fails. The same also applies to the calibration standards; it’s vital that what’s on the label is exactly what’s in the bottle.
