Jenco was founded by Mr. John Jen more than 40 years ago on the idea that innovative water quality instruments should be available at competitive price. Today, that idea is prevalent in all the products we manufacture, which now span pH, ORP, conductivity, dissolved oxygen, ion and temperature instruments for field, laboratory and industrial applications.
All Jenco meters are designed and manufactured in its ISO9001 and IECQ Hazardous Substance Process Management certified manufacturing facility in Shanghai, China. This same Jenco facility also designs and makes products for other high end water quality manufacturers.
