製品について

The hybrid gas density monitor combines self-acting monitoring with high-performance microswitches and continuous density measurement of insulating gases in one device. It covers demanding applications and maintains highest accuracy over a very wide temperature range. Trend analysis helps to detect possible leakages sooner, provides data for preventive maintenance measures and therefore facilitates compliance with greenhouse gas regulations. This precise and maintenance-free hybrid density monitor is reliable in operation over decades for indoor and outdoor applications.
