1970
Conducta, Gesellschaft für Mess- und Regeltechnik mbH & Co. was founded in Stuttgart-Stammheim by Heiner Jäckle on July 2, 1970. Initially, the company produced pH measuring transmitters and gas detectors. In 1973, a branch office was set up in Munich to increase market penetration. In 1981 Conducta was integrated into the Endress+Hauser Group with relocation to Gerlingen

1976
Innovative Sensors Inc. (ISI) was founded by Gary Bukamier in Anaheim, CA as a manufacturer of liquid analytical sensors for industrial and laboratory applications. ISI specialized in the OEM design and manufacturer of pH and ORP sensors for water quality and industrial applications. Patented technologies in both the reference and measuring half-cells became benchmarks within the industry.

1982
Wedgewood Technology, Inc. was founded by Bill Wynn in San Carlos, CA as a manufacturer of optical monitors and analyzers for the measurement and control of liquid solids concentration, color and turbidity. In 1985, Wedgewood introduced the world’s first systems specifically for Biotechnology with inline ultraviolet (UV) analysis and combination pH/Conductivity/Temperature measurement.

1994
ISI became the first independent pH manufacturer to be certified to the ISO:9000 quality standard.

1998
ISI introduced the world’s first and only automated pH bulb blowing machine.

1999
With a view to globalization and better access to the US Market, Endress+Hauser Conducta GmbH acquired Innovative Sensors Inc. on January 6, 1999.

2001
Endress+Hauser Conducta GmbH acquired Wedgewood Technology, Inc.

2002
Wedgewood Technology introduced the patented EZ Cal system for N.I.S.T. traceable inline calibration of optical analyzers.

2004
Innovative Sensors Inc. and Wedgewood Technology merged to become one company and renamed it Wedgewood Analytical Inc.

2005
Endress+Hauser Conducta acquired STIP Isco GmbH (Groß-Umstadt). STIP products which became the precursor to Endress+Hauser’s Analyzer division. these analyzers are predominantly used in water and waste water treatment.

2007
Direct sales of Endress+Hauser products moved to Greenwood, Indiana with all OEM and Label Sales remaining with Wedgewood Analytical in Anaheim, California

2008
Wedgewood Analytical in addition to offering Wedgewood optical sensors and Innovative Electrochemical sensors begins to offer labelled versions of Endress+Hauser products in North America.

Present
“Wedgewood Analytical” remains as the well-known brand name for our Optical family of products and pH/ORP, conductivity, oxygen, turbidity, and disinfection sensors and transmitters as is evident on this website.
