  • Relay Buddy PRO Test Kit

    191 - Electronic Specialties Inc.

    Relay Buddy is a quick go / no-go tester for the most common automotive relays. With the included adapters, Relay Buddy now tests 5 different relay types and also tests shielded relays. Relay Buddy provides you with an indication of the general health and functioning of the relay switch contacts and coil. It will check the control side of the relay by applying a signal to the relay coil while it checks for proper functioning of the relay contacts. Relay Buddy operates the relay several times during each test session as it watches for consistency in every cycle. Relay Buddy will fail the relay and light the RED LED if any one of the cycles proves unsuccessful during the test session.

This sensor is an extremely accurate digital (I2C interface) temperature and humidity sensing device, with +/-0.2C temperature and +/-2% humidity accuracy typical. These specs far exceed the accuracy of ICs that came before it, including the HTU2x and SHT1x series, and improves upon the success of the SHT2x that came before it. In addition, the SHT31-DIS-B has a wide input voltage range of 2.4V-5.5V and includes temperature isolation and airflow cutouts as recommended for the optimal operation. Finally, in the case of environmental changes that could cause light condensation, the SHT31-DIS-B has a built-in heater to burn off any condensate.

  • X-Ray And Gamma Detector Systems

    FAST ComTec GmbH

    The XR-100CR is a new high performance x-ray detector, preamplifier, and cooler system using a thermoelectrically cooled Si-PIN photodiode as an xray detector. Also mounted on the 2-stage cooler are the input FET and a novel feedback circuit. These components are kept at approximately -55 °C, and are monitored by an internal temperature sensor. The hermetic TO-8 package of the detector has a light tight, vacuum tight thin Beryllium window to enable soft xray detection. The XR-100T-CdTe represents a breakthrough in xray detector technology by providing “off-the-shelf” performance previously available only from expensive cryogenically cooled systems. The XR-100-CdTe is also suited for measuring gamma rays.

  • Tone & Probe Kits

    Triplett Test Equipment & Tools

    ProTone Wire Locator Kit features a powerful tone generator and a filtered, ultra-bright lighted probe. The CTX590 functions as a high quality wire locating tool that uses an inductive probe to sense a tone placed on the wires by its associated tone generator. The tone generator provides RJ11, RJ45 and insulated alligator clip connections. The Red/Green LED on the probe indicates continuity, voltage, and polarity. The probe also includes an ultra bright LED tip, fluorescent light noise filter and sensitivity control. The CTX590 can be used for tracking down short circuits, telephone central office connections, and other wire locating applications. Includes (2) 9V batteries and case.

  • Beam Directional Power Supply Mains

    SiteX CP300D - Teledyne ICM

    Teledyne ICM's CPSERIES has been designed with a view to revolutionizing the handling and performances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which Teledyne ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).

  • Colorimeter

    K10-A - Klein Instruments Corp

    The Klein K10-A has long been regarded as the industry standard in LCD calibration. It's enhanced optics give it a 3X advantage in sensitivity over the original K-10 SF. Known for it's superior speed, the K10-A can stream intensity data in 3.2 milliseconds, and can provide color data in 125 milliseconds. The Klein K10-A is also extremely sensitive and color accurate. Large photo-diodes give the probe superior performance even in extremely low light (down to 0.00006 cd/m2). Klein diodes are very large; 5mm x 5mm each, and are thermally stable and linear to report the highest degree of accuracy. The unparalleled speed and iconic design of this colorimeter have made it the most widely known Klein product.

  • Color Measuring Unit

    Colorette 4 - Probat Burns

    The Colorette 4 serves for precisely measuring the colour of ground roasted coffee. By means of the stripping device, the sample to be measured is prepared and afterwards positioned at the measuring point. The Colorette works according to the principle of reflection measurement. A ground coffee sample to be measured is illuminated with a white clock-pulsed LED. For colour value determination, the reflected light is thereby captured by a sensor. The determined colour value is afterwards indicated on the touch screen. The indication in different scales makes it possible to use the device flexibly and to adapt it individually to the requirements. Thanks to the improved components, the Colorette 4 is low-wear and guarantees most exact measuring results during the entire lifetime. The extended connectivity offers various integration possibilities into processes and systems.

  • Endoscopes

    PCE Instruments

    Originally designed for the medical sector, endoscopes are the ideal tool for inspection and maintenance today. Endoscopes offer new perspectives to viewing the insides of machines. Thanks to their flexible fibre optic cables and light weight enclosure, these extraordinaryEndoscopes are the ideal tool for inspection and maintenance. endoscopes can locate problems and conflicts of the system very easily and quickly, allowing for preventative measures to be taken without the need to dismantle the machinery first. Complex dismantling of machines is usually very time and cost intensive. With the help of endoscopes, inspections in industrial sector can therefore be organized considerably faster, more aimed and more cost-efficiently Endoscopes are used mainly by electricians, security personnel, specialists in the professional sector, and mechanics of all types.
