  • Gas Filter Correlation CO​​​​ Analyzer

    ​Model N300 - Teledyne Advanced Pollution Instrumentation

    The Model N300 is a microprocessor-controlled analyzer based on the Beer-Lambert law that is used to determine the concentration of carbon monoxide (CO) in a sample gas.The N300 uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb Infrared (IR) light. The analyzer passes the IR light beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.

  • UV Accelerated Weathering Testers

    Dongguan Amade Instruments Technology Co., Ltd

    UV accelerated weather tester is also well known as UV test chamber, which is a type of environmental test chamber using fluorescent UV as light source to determine the resistance of plastics, leathers, rubbers, fabrics and so on to weathering under the specified conditions. We know that Ultraviolet light only accounts for 7% of the total sunlight, but it plays a core role in deterioration of materials. Not only does the ultraviolet, but UV test machine also can simulate dewing, high temperature, high humidity, black environment to be reappeared as a circulation. So UV weathering test is an essential measure for people to research and know the degradation state of specimens in advance as the time goes on.

  • Real Time Switch

    Ajinkya Electronic Systems

    Real Time Switch is a real time timer which can be used to switch electrical appliances like street lamps, garden lights, corridor lights, neon signs etc as per time of the day. The timer has built in almanac timings fixed in nonvolatile ram so that the user does not have to programme the unit from time to time. This has added advantage over daily dial or weekly timers. Timer provides two outputs to drive contractors of different ratings. These outputs can be used with different combinations to achieve desired output. Timer is provided with manual override facility. Optional detachable external keyboard unit provided to avoid unauthorized access.

  • Color Tests

    LED-Check - Fiber Vision

    LEDs are the standard light source in car cockpits. It is not sufficient to find out if a LED shines, or not. The LED needs to have precisely the specified brightness and color to fulfil its function.The FiberVision LED-Check system tests up to 250 LEDs in less than one second.

  • Conductivity Switches

    AMETEK Drexelbrook

    B/W Controls offers a simple conductivity holder and electrode that can be configured for multiple measurement points.

  • High Collector To Emitter Voltage

    Renesas Electronics Corp.

    High collector-to-emitter voltage photocouplers (optocouplers) are optically coupled isolators containing a GaAs infrared light emitting diode and an NPN silicon Darlington connected phototransistor. The isolation voltage during input and output and the voltage between the collector and the emitter of the transistor are both high.

  • Luminescence Sensors

    DK50-UV - Pepperl+Fuchs GmbH

    DK50-UV luminescence sensors detect marks that blend into a background or are invisible, even on irregular backgrounds, and deliver a sensing range of 600 mm. A light spot with a small focal point allows the user to detect small parts and invisible marking down to 2.2-mm-diameter targets.
