How to Choose a Chemical Oxygen Demand Analyzer Manufacturer?

It is important to keep in mind that selecting a COD analyzer is not just about selecting a suitable machine. It is about making a partnership that will allow you to test water quality for several years to come. The turnaround time for analyses is dependent on the manufacturer behind the instrument; therefore, the time, support, quality, and reliability of your analyses directly correlate to the manufacturer. With the numerous options available in the marketplace, understanding how to narrow your search to the most qualified chemical oxygen demand analyzer manufacturer will help to save you time, money, and aggravation.

A manufacturer who is providing a complete solution will not just provide a box, but will provide complete and reliable instruments, responsive and ongoing service, and the technical support to help you maximize your investment in equipment. The key issues to keep in mind are stated below.

Experience and track record

The first thing to evaluate is the time that the manufacturer has been in the industry. Testing water quality requires specialized knowledge, especially when it comes to sampling, optical systems, and reagent chemistry. It is likely that a manufacturer who has decades of experience has already solved the problems that other, newer manufacturers are still struggling with.

The experience gained over many years proves the durability and reliability of their products. They develop their products based on customer feedback and a genuine understanding of the challenges their users face. They know firsthand the issues, the equipment failures, and the needs of users that occur on the front lines.

A chemical oxygen demand analyzer manufacturer with a long history has proven that their products stand up to real world use. Track record and reputation are built over time.

Product range and versatility

The different needs of users in different environments require that manufacturers offer a choice of models. A high throughput model with sophisticated data acquisition and management systems will be the choice of a laboratory. A field technician will require a unit that is portable, robust, and easily transportable. A smaller treatment plant will require a unit that is capable of being placed on a bench and is simple to operate.

A good chemical oxygen demand analyzer manufacturer has to be large enough and established enough to offer this range of options. A quality manufacturer will provide flexibility in your choice of equipment designed for particular applications, rather than trying to make one machine do everything.

When considering manufacturers, look at their entire range. Do they have portable analyzers for field work? Bench models for labs? Do they provide reagents and consumables? A manufacturer with a full line makes it easier for you, as you have a one stop shop for everything.

Technology and innovation

Measurement technology for COD has evolved. In the past, methods were time consuming and used high quantities of dangerous reagents. With the newest analyzers, results can be obtained in minutes using smaller quantities of samples and generating less waste. The leading manufacturers keep ahead of the trends.

Information about the technology of the instruments should be available. Do they offer sealed reagent vials to reduce the risk of exposure? Is the digestion process rapid and well controlled? A manufacturer who spends time and money on research and innovation will have answers to these questions.

In a chemical oxygen demand analyzer manufacturer, innovation means they care about improving their products. They do not want to have the same analyzer for 20 years. They are interested in how to keep testing more efficient, safer, and more accurate. That commitment to improvement benefits you over the long term.

Quality and reliability

Your COD analyzer is an investment, and like any investment, you want a return. An analyzer that is not reliable or causes uncertainty with your results is not an analyzer worth having.

When considering a potential manufacturer, determine as best as you can how much they value quality. Do they own their own production facilities? Having control over the manufacturing process provides them with the ability to ensure consistency across units. This extends to having the ability to inspect materials, control production, and test every instrument before it leaves the factory.

Word of mouth can often give a good sense of quality. Ask around and gather information. Details like failure rates and feedback from previous customers will speak volumes about a chemical oxygen demand analyzer manufacturer that is willing to back their product.

Support and service

As good as your analyzer may be, it will require support at some point. Whether it is a question about operation, an unforeseen event, or the need for calibration, you want a manufacturer who responds quickly and knows their products inside and out.

Inquire about their technical support. Is it offered during your hours of operation? Can you contact someone by phone or email? Are there support centers in your area? A manufacturer who values support is customer oriented.

Support can also take the form of training. Some manufacturers offer training on their equipment. This is particularly important if you are new to COD testing or if several people in your organization will be using the apparatus. A manufacturer who provides training helps you maximize the return on your investment.

Consumables and long term availability

Reagents and other consumables are required for the operation of your COD analyzer. It is imperative that you confirm the availability of these supplies for the entirety of the instrument’s lifespan. A manufacturer who stops providing consumables without advance notice renders your equipment obsolete.

When searching for a chemical oxygen demand analyzer manufacturer, look for one that provides long term product support. It is important that their commitment to you is reliable and will not leave you stranded. Some manufacturers offer locked specifications for repeat orders, meaning the reagents you order today will be the same for years to come.

Compliance and standards

COD results are likely to be used for regulatory and legal compliance reporting. It is critical that your analyzer produce results that are defensible. This means that the analyzer must be designed to comply with the standard methods and guidelines accepted by the industry.

Always ask the manufacturer about compliance. Do their instruments meet EPA guidelines? Are they designed according to recognized methods like the dichromate digestion method? A manufacturer who understands the regulatory landscape will help you stay compliant.

Many experienced and reputable chemical oxygen demand analyzer manufacturer know what their customers expect in relation to compliance. They build their instruments with the purpose of giving their customers the certainty that the data provided is correct, verifiable, and defensible.

Value beyond the price tag

Taking price into consideration when purchasing an instrument is undoubtedly important, however, it should not be the only consideration. While a lower priced instrument can save some money on the initial purchase, if it breaks down often or if the results it produces are inconsistent, the long term costs can be even greater. Rather than focusing on the purchase price, consider the total cost of ownership.

Factors that need to be considered when determining total cost of ownership include the cost of consumables, the cost of calibration, repair costs, and the availability of support. A manufacturer who builds durable instruments and provides support when needed offers real value.

A chemical oxygen demand analyzer manufacturer with in depth knowledge of their products will be open with customers about long term costs. They are not secretive about consumables and service costs. This demonstrates their commitment to customer satisfaction.

Customer feedback and reputation

While a manufacturer can say a lot about themselves and their products on their own website, the most reliable and honest information comes from their users. Reviews and testimonials from people who have used the product are the most valuable sources of information. If you can, reach out to these users and ask them about their experiences.

Years of positive feedback and returning customers build the reputation of a quality chemical oxygen demand analyzer manufacturer. They have customers who recommend them to others because their experience has been positive. Reputation like this does not happen overnight. It takes years of consistent delivery to build.

Conclusion

Your water quality testing program will greatly depend on the COD analyzer manufacturer you choose. The right manufacturer will give you quality instruments, responsive support, and the peace of mind that comes from knowing your data is accurate.

Look for years of experience. Look for a variety of offerings that meet your criteria. Look for innovative solutions. Look for high quality standards. Look for a commitment to service and support. Look for a strong reputation.

A quality chemical oxygen demand analyzer manufacturer values your work and strives to develop equipment that you can depend on for years to come. When you make the right choice, you get the right equipment and the confidence that comes from knowing you made a sound decision.
