Jenco was founded by Mr. John Jen nearly 30 years ago on the idea that innovative water quality instruments should be available at competitive prices. Today, that idea is prevalent in all the products we manufacture, which now span pH, ORP, conductivity, dissolved oxygen, ion instruments for field, laboratory and industrial applications. Jenco products are manufactured in its ISO: 9001 certified facility and distributed worldwide by our dedicated distribution partners.
