  • Spectral Sensor

    AS7264N - AMS Technologies AG

    XYZ Chromatic Color and 440/490nm Blue Sensor with Electronic Shutter. The AS7264N provides direct XYZ sensor data which conforms to the tri-stimulus standard observer color response of the human eye. In addition, two channels added for measurement of blue spectrum light, plus a near-IR channel enables additional application flexibility. LED drivers with programmable currents are provided for electronic shutter applications.

  • Spectroradiometers

    Photometric Solutions International Pty Ltd

    After the SP-3C has acquired a spectrum, it is displayed on the screen along with the chromaticity coordinates and (if appropriate) the colour temperature of the source and other derived data. Integration times can vary from 1 millisecond up to 60 seconds. For bright light sources, the chromaticity coordinates can be updated on the screen multiple times per second. The spectra can be logged over time, making the SP-3C a very handy research tool for monitoring the change in colour of a sample over time.

  • Under/Overvoltage Monitors

    Acopian Technical Company

    Contacts to control an external horn or light, or to signal your PLC are now available on independent accessories for any power supply. These modules can be used on power supplies with DC voltages from 5 to 125 Vdc. SPDT relay contacts switch if the power supply’s output deviates by:*1.0 volt or more (for 5 volt outputs)*2.0 volts or more (for 6 to 48 volt outputs)*3.0 volts or more (for 49 to 125 volt outputs)

  • XUV spectrograph

    UltraFast Innovations GmbH

    Our XUV spectrograph features an aberration-corrected flat-field wavelength coverage from 5nm to 80nm using a single grating. In the range between 15 and 80nm, the spectrometer can be used without entrance slit over a range of source distances to maximize light collection. Its modular design is able to match different experimental geometries and configurations. It features an integrated slit holder and filter insertion unit, as well as a motorized grating positioning.

  • Video Endoscopes

    PCE Instruments

    Video endoscopes are the ideal tool for inspection and maintenance. Video endoscopes offer new perspectives to theVideo Endoscopes are the ideal tool for inspection. insides of machines. Thanks to the flexible fibre optic cable and light weight enclosure, these extraordinary optical video endoscopes can locate problems and conflicts very easily and quickly, allowing for preventative measures to be taken without the need to dismantle the machinery first.

  • Gaussmeters

    PCE Instruments

    Where is electromagnetic radiation created?Gaussmeters in use.Gaussmeters in use.Below you will see two pictures with different places where electromagnetic radiation is created. Electromagnetic waves do not need any medium to expand themselves but even in vacuum they travel at the speed of light regardless of their own frequency. They are transverse electromagnetic waves that means that their propagation direction is always perpendicular to the oscillation direction of electromagnetic fields.

  • Viscometer

    ViscoStar III - Wyatt Technology

    A highly sensitive, on-line differential viscometer used in conjunction with SEC-MALS to determine the size and conformation of all types of biopolymers, synthetic polymers and even proteins and peptides. The ViscoStar III incorporates multiple novel technologies to provide the highest sensitivity, stability and solvent compatibility of any available viscometer for GPC. Its ease-of-use and serviceability make it the perfect companion for Wyatt's DAWN HELEOS II light scattering and Optilab T-rEX refractive index detectors.

  • Visual Fiber Fault Locator

    D0650 - Appointech, Inc.

    Visual Fiber Fault Locator is used forlocating broken point in fibers. The LightSource is a 650nm laser diode,modulated at 7 Hz. When a fiber isconnected to the fault locater, the laserlight is coupled into the fiber, andpropagates along the fiber until at abroken point, where the light will bescattered out of the fiber, appearing tobe a blinking red spot. Therefore thedetection of a broken fiber point is quickand easy. It comes with a ball-point pen.

  • Voltage Detector

    ZhangZhou Weihua Electronic co.,ltd

    A device that tells the user whether an object has an electrical charge. It can be a simple, pen-shaped piece of testing hardware that indicates the presence of electricity, or it can be an advanced tool used to detect precise voltage levels in electrical systems. Voltage detectors use either visual or audio cues to tell the user whether voltage is present. Some are equipped with lights and numbers that indicate the level of voltage, while a less advanced voltage detector might simply make a beep to indicate that a level of detectable voltage is present.
