Valley Instrument Service was founded in 1971. The original focus of the company was to provide repairs and calibration for the many instruments used in the steam flood process of extracting oil from the fields of Kern County. Since that time our company has evolved into a service and supply entity that provides the best instrumentation available for our customers.
We not only sell but also service most of the instruments in our service facility. In addition, we supply much more by stocking instrument fittings, pressure gauges, thermometers, thermowells and tubing. We also manufacture custom Thermocouples and RTDs in our facility in Bakersfield, CA
