Image result for jenco instruments
JENCO INSTRUMENTS was established more than 40 years ago on the idea that innovative water quality instruments should be available at competitive prices and their mission is to bring innovation to anyone who works with analytical instruments.

Since the launching of the world's first portable digital pH meter in 1975, Jenco Instruments has continued to focus only on building water quality instruments for measuring pH, ORP, conductivity, TDS, salinity, resistivity, dissolved oxygen, ion, turbidity and temperature. 

This single minded-focus is combined with Jenco's obsession with finding the best balance between quality and value - whether it is the simplest testers or the most advanced, gesture-operated, WIFI-enabled benchtop meters.
