BASIC INFO
Yokogawa EXA GD402 Gas Density Analyzer

There are many applications where the accurate, repeatable measurement of gas density is essential. From blending of fuel, to product quality, to Hydrogen purity and replacement in utility turbines, Yokogawa's family of Gas Density products allow you to make accurate measurements with superior reliability and ease of maintenance and operability.

The Model GD402 gas density analyzer and Model GD40 detector not only provide continuous measurement of gas density, but also several other valuable parameters, including specific gravity and molecular weight. The GD40 detector is designed for intrinsically safe and flameproof, explosion protected applications. It is designed to be virtually maintenance free for all accepted applications.

The Model GD402 is a rugged microprocessor-based converter designed in two versions to meet both general area and explosion-proof application requirements. In addition to the display of several key data items, the converter also provides the choice of three different means for calibration: automatic; semi-automatic and one-touch manual operation.

  • Proven Design
  • Many detector features
  • Simple, user-friendly interface
  • Low installation cost
