This pressure gauge has been designed for high-precision applications and is equipped with a stainless steel Bourdon tube. Its case is of dust proof type. As a gauge high-precision measurement for research work, this pressure gauge is used for research and experiment, and for calibrating secondary gauges as a standard pressure gauge.

A Bourdon tube of this gauge has been especially designed for high-precision applications. This Bourdon tube is also provided with excellent corrosion resistance.

To secure safety of operation in case this pressure gauge breaks during direct reading, a blowout disk window is provided as a standard.
