    Part of towing responsibly is making sure your trailer lights are working properly. Whether you have just installed a new vehicle-to-trailer wiring harness or are trying to locate the cause of an electrical problem, CURT connector testers are great for testing tail lights, turn signals, brake lights, ground connections and other electrical components on your trailer.

  • Digital Illumination Meter

    Shenzhen UYIGAO Electronic Technology Co., Ltd

    Is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include either digital or analog electronic circuit, which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed.

  • DB-9 PockeTester™

    Model 51 - Patton Electronics Co.

    The Patton Model 51 DB-9 PockeTester™ monitors the seven most important async EIA-574 (RS-232 on a DB-9) data and control lines. The Model 51 uses seven tri-state LEDs to indicate the presence of the following signals: TD, RD, DTR, DSR, RTS, CTS and DCD. A red light = Mark, a green light = Space and no light indicates no signal on the line. No AC power or batteries required..

  • Flash Parallel Solar Simulator

    All Real Technology Co. Ltd.

    All-Real Flash Parallel Solar Simulator - HCPV module tests comprises three major parts of flash light source, HCPV module power rating station and IV Tracer. Light Source and collimated mirror: The collimated angle of radiation is within ± 0.5° very similar to the real sun (with a controlled reference spectrum similar to AM 1.5D) to well simulate natural sun light and leads to accurate measurement. IV Tracer:

  • Fork Sensors

    SICK Sensor Intelligence

    Fork sensors, which operate using a through-beam design, combine the sender and receiver in a single housing. As a result, alignment is no longer time-consuming. Even very slight differences in light attenuation are detected due to highly focused light emission and high detection accuracy. Easy installation, high immunity to ambient light, and a wide range of fork widths are some of the many advantages that SICK fork sensors offer. Applications include detecting labels or parts on conveyors.

  • Fiber Break Tester

    27555 - C2G, Lastar, Inc.

    Sends a visible red laser light down the fiber locating any breaks or unseen faults. The Fiber Break Tester from Cables To Go is a pocket sized tool that sends a visible red laser light though fiber optic cables. Breaks or faults in the fiber will refract the light, creating a bright glow around the faulty area.

  • Fiber Installation Tools

    FiTs - Liverage Corp

    The FiTs is a handy instrument to provide several wavelengths for testing the fiber equipment in an optical network and FTTx construction. There are 650 nm Fiber Checker & Light Source is deal for field or laboratory testing of optical communication systems at visible light 650 nm and 850 nm / 1310 nm / 1490 nm / 1550 nm . Light Source features zero warm up, superb productivity and is easy to use with its pocket-size and rugged handy design.

  • Handheld Spectrometer

    UPRtek PG100N - Gamma Scientific Inc.

    The PG100N is a lightweight, portable, and easy-to-operate Spectral Light Meter or Spectral Illuminance (LUX) Meter designed for agriculture and horticulture applications. It is an interactive system and offers analytical reporting for spectrum, PPFD, PFD, auto-monitoring, and other parameters needed to understand ambient light conditions for plant growth and the adjustment of artificial light sources to efficiently control production, safety, and yield.

  • Photocell Relays

    Entes Elektronik

    FG type photoelectric (twilight) switches monitor the daylight in connection with a light sensor (light dependent resistor, LDR) specially developed for this purpose. These switches are used on yards, streets or shop windows for automatically switching the lights ON at the beginning of darkness and switching them OFF in the morning. The sensor is installed in a water tight, surface mount container that is made of heat resistant acrylic material.

  • Radiometers
