  • Color Monitoring Unit

    Colorette 3B - Probat Burns

    Achieve consistent results by monitoring and precisely controlling the degree of roasting with the Colorette 3B color-measuring unit. Unaffected by ambient light, this portable and extremely accurate device uses infrared and red LEDs to measure the exact color of ground coffee samples. It then displays the measurement and automatically prints a complete record, including the color value, sample number, roaster number and batch date / time.

  • Combline Filters

    Teledyne Microwave Solutions

    Combline filters are bandpass filters used in the frequency range of 100MHz to 20GHz The structure consists of a series of TEM resonators of circular or rectangular cross-section resonated by a capacitor at the open circuit end. The bandwidth and response of the filter is governed by the coupling of each resonator to its immediate neighbor. This is also a function of the resonator size, resonator spacing and ground plane separation. Typical construction is silver-plated aluminum, which achieves the lowest passband loss while maintaining a light weight. Computer design programs result in close correlation between theoretical and actual performance.

  • Degree of Polarization Meter

    DOP-201 - General Photonics Corp.

    The DOP-201 measures and displays the Degree of Polarization (DOP) of a light source in real time on the front panel display. The instruments incorporates a patented maximum & minimum search technique that accurately measures both low and high DOP. This technique is superior to polarimeter-based methods that are inaccurate at low values of DOP as well as scrambler-based methods which are less accurate at high values of DOP.

  • Confocal Raman Microscope

    inVia Qontor - Renishaw Inc.

    The new inVia Qontor is Renishaw''s most advanced Raman microscope. With the addition of Renishaw''s latest innovation, LiveTrack™ focus tracking technology, the inVia Qontor enables users to analyse samples with uneven, curved or rough surfaces. Optimum focus is maintained in real time during data collection and white light video viewing. This removes the need for time consuming manual focusing, pre-scanning or sample preparation.

  • Brix Refractometer, Sugar Concentration & Refractive Index

    PA202 - MISCO Refractometer

    Dual-scale digital refractometer with scales for measuring both Brix (to 85) and refractive index (to 1.5000). Brix is a measure of sugar concentration and is used extensively in the agriculture and food and beverage industries. Refractive index is a fundamental physical property of a solution and is related to the speed light travels through it. Both the Brix and refractive index scales can be used to measure a nearly unlimited number of fluids.

  • Fiber Optic Laser Source

    VLS-13/15 - ViewTEQ Electronics

    When used with a power meter, the VLS-13/15 light source allows technicians to perform precise insertion loss measurements on single mode fiber optic connectors, passives, and link loss of installed cable at two wavelengths. It has continuous wave and four modulated outputs at 2Hz, 270Hz, 1KHz and 2KHz, allowing the use of most fiber identifiers or leak detection probes.

  • Fiber Optic Talk Set

    Huihong Fiber Inc

    Fiber optic talk set consists of both the fiber optic light source and transceivers, which carry voice over the spare fiber in both directions. When doing the test work, technicians may need remote location communication during the measurement or splicing work, and sometimes radio-based communications may not be suitable because of environmental conditions such as FCC restrictions, etc. fiber optic talk set will function well in such cases, they could utilize the already installed fiber optic link to carry voice communications.
