  • UV Absorption O3 Analyzer

    Model T400 - Teledyne Advanced Pollution Instrumentation

    The Model T400 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.

  • 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.

  • UVB Sensor

    PMA 2101 - Solar Light Company Inc.

    The UVB sensor PMA 2101 biologically-weighted erythema gives an accurate measurement of ultraviolet radiation from sunlight or artificial light sources, also called sunburning UV radiation (SUV).Its spectral response follows closely the erythema action spectrum. The detector has angular response very close to an ideal cosine function (Lambertian response) making it suitable for measurements of diffuse radiation or radiation generated by extended sources.

  • UV Meter

    A-SUN TEST LTD.

    This affordable UV meter detects both atmospheric UV-A and UV-B light ranging from 400 nm to 280 nm. It displays the current atmospheric UV index and the UV Irradiance. UV-A and UV-B are the UV rays that penetrate the atmosphere. A graphical meter alongside a UV color code chart makes it easy to determine the level of UV risk.

  • 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.

  • Zinc Oxide Arrester Tester

    SFB150 - Shanghai Launch Electric Co., Ltd.

    Zinc oxide arrester tester is specifically designed to detect internal electrical defects of power system with 10KV and below using MOA valve clearance indirect contact and to measure leakage current under MOA DC reference voltage (U1mA) and 0.75 U1mA. The instrument integrates high-voltage DC power supply, measurement and control system. All components are concentrated in a single chassis, with small size, light weight. It is a must for power system and zinc oxide arrester tester manufacturer field test.

  • Voltmeters

    AMPTEC RESEARCH

    ARC Flash No Volts Meter is an ultra-safe portable digital voltmeter. It can provide testing of voltage on firing and related system lines. The 620EXV is certified to meet USA MIL. STD. 810 MTD. 511, therefore compliant for use in explosive atmospheres. This product will accurately inform its operator using red and green lights (which can be set to custom levels) to indicate whether or not the voltage level conforms.

  • Wavelength Tracker

    10717A - Keysight Technologies

    The Keysight 10717A Wavelength Tracker tracks changes in the air's index of refraction to optically compensate for environmental changes. It uses one axis of a laser measurement system to report wavelength of light changes, not changes in position. It is used to correct displacement values reported by other measurement axes in the system, hence improving measurement accuracy. It provides a higher degree of accuracy than environmental sensors such as the 10751C and 10751D Air Sensors.

  • 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.

  • Voltage Detectors

    Salisbury

    Self-Testing Voltage Detectors are used to verify live or de-energized conductors. These testers may be used with rubber insulating gloves or hot sticks using the splined universal end fitting. Testers indicate the presence of voltage with an extra bright LED light and a distinctive audible signal. It is recommended that the tester be moved closer to the conductor until a warning is indicated, or it touches the conductor, apparatus, or elbow test point. Each tester requires three “C” batteries (included).

  • Voltage-Pen-Detector

    A-SUN TEST LTD.

    Are a relatively simple testing instrument that enables electricians and other uses tolocate, trace and identify common electrical problems. These testers can locate wires behind walls, underground,and inside junction boxes. Others are designed to find blown fuses or test light fixtures. Some testers can evenlocate neutrals, ground faults, and high voltage lines without interrupting power
