A Legacy of Precision and Reliability for Your Most Challenging Requirements
In 1850, Edward Ashcroft met Eugene Bourdon in Paris and subsequently purchased the patent rights to produce his invention ̶ the Bourdon Tube ̶ in the United States. It was a revolutionary design and is still the most commonly applied elastic element in mechanical pressure gauges today.
More than 60 years later, an Ashcroft employee named Otto Heise began to refine the Bourdon tube and the pressure gauge to yield higher accuracy. Since starting his own precision gauge company, these gauges have remained the gold standard for mechanical pressure instruments. But more was yet to come. Evolving technology has led to Heise® electronic pressure indicators and transducers with even greater accuracy.
Today, Heise® precision pressure instruments of Ashcroft Inc. and continue to lead the way in high accuracy pressure measurement.
Otto W. Heise started the Heise Bourdon Tube Company in the late 1920s
In 1973, Ashcroft Inc. purchased Heise® from Otto Heise.
