Jenco Instruments

Jenco is a family-owned manufacturer with a 45 plus year history in designing and building water quality instruments for measuring pH, ORP, conductivity, TDS, salinity, resistivity, dissolved oxygen, ion, turbidity and temperature. Founded in 1973 with the idea to combine the then latest in semiconductor technology with water quality instruments, our small OEM manufacturing company was able to develop and build the world’s first digital portable pH meter, which drastically improved measurement results and reduced manufacturing costs as compared to legacy products on the market. Today, this pioneering sprit and a relentless focus on quality and value continue to guide us to build the best next generation products—from the simplest testers, to advanced app-enabled benchtop meters, and to mission critical continuous monitoring process instruments. Jenco-branded instruments are sold throughout the world by our distributors—businesses that resell our products to individuals, businesses or institutions. As an OEM or ODM service provider, Jenco's partners utilize our in-house design, engineering, tooling, manufacturing, quality assurance and logistics expertise to quickly ramp up with customized water quality products for a wide variety of industries and applications.
