  • Guided Wave Radar Level Transmitter

    2291 - Georg Fischer Signet

    The 2291 Guided Wave Radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. The 2291 level gauge operates based on the well-known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse.

  • Highly Sensitive Silica Monitor

    SLIA-300 - HORIBA, Ltd.

    The ultra-pure water that is used in the semiconductor production processes can be further purified by using an ion-exchange resin. Capturing the silica that is dissolved from this ion-exchange resin as quickly as possible can control the ultra-pure water quality, which is important during the production processes.HORIBA Advanced Techno has developed and employed a new "long light path length measurement cell" to enable highly sensitive measurement of ultra-low density silica and also realized a compact desktop model to improve the usability.
