Widely used to test trailer light circuits on most trucks, boats, trailer campers, caravans, food trucks and other trailers.

  • Integrating Sphere


    The simpler way to measure the total luminous flux of lamps and luminaires is to use an integrating sphere photometer system. It is a device to perform spatial integration of flux optically, thus the total luminous flux can be measured with one fixed photometer head and measurement can be instant. An integrating sphere photometer is calibrated with a total luminous flux standard lamp. A test light source is measured by comparison to a standard lamp calibrated for total luminous flux.

  • Compact EMC Test System

    Multi-CE5 - Hilo Test

    The Multi-CE5 includes an Electrical Fast Transient Generator (EFTG), a Combination Wave Generator (CWG) and a Coupling-/Decoupling Network (CDN) for single-phase power supply lines. The software program CE-REMOTE allows full remote control of the test generator via Ethernet light guide as well as recording, evaluation and documentation of test results, according to IEC 17025. To record the wave shape of impulses, it is equipped with an Impulse Recording Function (IRF).

  • UV Absorption O3 Analyzer​​​

    Model N4​00 - Teledyne Advanced Pollution Instrumentation

    The Model N400 Ultraviolet (UV) Absorption analyzer uses a system based on the Beer-Lambert law for measuring low ranges of ozone in ambient air. A 254 nm UV light signal is passed through the sample cell where it is absorbed in proportion to the amount of ozone present. Periodically, a switching valve alternates measurement between the sample stream and a sample that has been scrubbed of ozone. The result is a true, stable ozone measurement.

  • Multiple Output Programmable Linear DC Power Supplies

    TP3303 Series - Twintex Electronics Co., Ltd

    The TP3300 series programmable DC power supply are light weight, adjustable, multi-functional work stations. They have three independent outputs: two with adjustable voltage level and one with fixed level selectable from 2.5V, 3.3V and 5V. The power supply can be used for logic circuits where various output voltage or current are needed, and for tracking mode definition systems where positive and negative voltages with good accuracy are required.

  • UV-A LED Panel Flood Lamps

    PowerMAX™ 365 Series - Spectronics Corp

    PowerMAX 365 Series flood lamps feature a panel of 16 powerful UV-A (365 nm) LEDs specially engineered for non-destructive testing applications. These versatile, stationary light sources can be installed overhead or in-line, and can be ganged together to provide an even wider coverage area. UV-A LED panel flood lamps are also available in two standard-intensity models that are designed for NDT inspection applications requiring limited UV-A output.

  • Far Infrared Systems

    Sciencetech, Inc.

    Far-Infrared and terahertz (THz) radiation is the spectral region at the long wavelength end of the infrared and the short end of the microwave region, also known as the sub-millimeter wavelength spectral region. Recently, there has been an explosion of interest in THz applications as the radiation generated can penetrate various materials. THz light is commonly used in materials science, security, pharmaceutical com- pound analysis, biomedical imaging, superconducting materials, astronomy, and particle physics research.

  • Relay / Magnetic Field Testers

    PeakTech Prüf- und Messtechnik GmbH

    Ideally suited for checking magnetic fields and the correct function of coils, e.g. Relays and solenoid valves. The magnetic field detector works without contact, so that opening the housing is not necessary in most cases. When a magnetic field is detected, the probe tip lights up permanently blue, with clocked relays in the same cycle as they are controlled. The function of the magnetic field detector can be checked before each measurement with the enclosed test permanent magnet.
