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.

Jenco Instruments was founded in 1973 with a new approach to designing and building water quality instruments. By combining the then latest in semiconductor technology and the ingenuity of their R&D team, their 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 spirit and a relentless focus on quality and value continue to inspire us to build the best next generation products—from the simplest testers, to advanced app-enabled benchtop meters, to mission critical continuous monitoring process instruments.
