How we work with you
ODM
ODM
As your original design manufacturer (ODM) partner, you gain access to Jenco’s in-house engineering, product management, production, quality assurance and industrial design teams to turn your water quality product ideas into commercially viable products. The integrated approach of designing and building your products lets us realize cost-down opportunities while keeping tight control over quality from design to build.
OEM/Private Label
In 1973 we began life as an OEM, private labeling for the then largest catalog companies in our industry. Private labeling with Jenco means we rebrand our products according to your branding specifications, including custom faceplate designs, housing colors, new manuals and packaging. No large stocking orders required, all it takes is a small setup fee and you’ll be all set to go.
Supply Jenco-Brand Products
Jenco does not sell directly to the end-user and we rely on our distribution partners to present our products to the market. As a Jenco distributor, you’ll leverage Jenco’s branding and marketing initiatives to sell Jenco products to your customers, while Jenco provide sales and technical support before, during and after your customers’ purchases.

Water Quality 101: What Is pH in Water Testing?
One of the most important indicators for water quality is its pH level. The pH scale runs from 0 to 14 and measures the acid or base quality of water. A pH of 7 is neutral, while a reading below 7 is acidic, and one above 7 is alkaline or basic.
