D402 and GD40 gas density detectors can not only measure gas density continuously, but also measure important parameters such as specific gravity and molecular weight of gas. The GD40 detector is designed for intrinsically safe, fireproof, explosion-proof applications, and it is designed to be maintenance-free for all accepted installations.
Model GD402 is a rugged microprocessor based converter designed in two versions to meet the requirements of general field and explosion proof applications. In addition to displaying several key data items, the converter offers three different calibration methods to choose from: automatic, semi-automatic and one-button manual operation.
