  • Brush or Sponge Pilling Tester

    TF222 - TESTEX Testing Equipment Systems Ltd.

    Brush or Sponge Pilling Tester, to determine the pilling propensity and simulate normal wear of knitted and woven fabrics used in apparel and automotive interiors by brush and/or sponging specimens together in a circular motion to form pills. Specimens are evaluated under standard lighting conditions using a pilliscope, light cabinet or similar, against users’ standard fabrics or piling photographs.

  • OZONE MONITOR

    727-3 - Mast Development

    Upon entering the instrument, the sample is diverted by the gas valve into the catalytic converter which selectively changes any ozone present to oxygen. This sample, with no ozone, then passes though the absorption chamber where the detector measures the amount of ultraviolet light transmitted through it. Upon completion of this cycle, the valve is activated and the sample containing ozone is passed through the absorption chamber. The absorption by ozone of the ultraviolet radiation at a wavelength of 254nm is measured at the sample detector, and displayed in parts-per-million (ppm) ozone.

  • Panel Light-I-V Teste

    ASIV-11 - Greensolar Equipment Manufacturing Ltd.

    The Panel Light-I-V Tester (ASIV) is used to test photovoltaic panels or modules during their production. A flashlight illuminates the work piece with similar light spectrum to that of the Sun, while the electric performance of the unfinished panel or the finished module is accurately measured. With the help of the tester the user can filter out reject panels. Testing the final performance reveals changes made by alternations in the deposition recipe.

  • Optical Channel Checker

    OCC-50 - ShinewayTech

    OCC-50 Handheld CWDM Optical Channel Checker is specially designed for CWDM installation, maintenance and troubleshooting, which is able to measure and monitor power values of up to 18 CWDM channels. OCC-50 can replace high-cost Spectrometers and conduct quick and reliable measurements in all environments. Thanks for its light, compact and sturdy design, OCC-50 is the ideal tool for CWDM installation and maintenance technicians.

  • pH Controller

    MC122 - Milwaukee Instruments

    With Milwaukee's MC Controllers you can monitor and control pH and/or ORP levels. The Milwaukee Instruments "MC" Controllers have a user selectable set point and a visual "Power Activated" LED notification light. Power to the controller box is turned on when the reading is Above or Below ( user selected ) the selected set point. These MC Controllers are ideal for CO2 or ozone dosing.

  • Photomultiplier Tubes

    Hamamatsu Photonics K.K.

    Photomultiplier tubes are being put to use as high-speed, high-sensitivity optical sensors in an increasingly broad spectrum of applications ranging from medical care and academic fields to industrial fields. Hamamatsu Photonics is renowned for development prowess that provides scientists everywhere with optimized performance, not only in the detection of faint light, ultra-high speed phenomena and other events, but in special applications as well.

  • Phototherapy Meter

    PR450 - Irradian Ltd.

    The PR450 phototherapy radiometer comprises of a microprocessor controlled display unit with key switch control and large numerical display. The detector assembly has a photodiode detector with optical coloured glass filters to give a spectral response peaking at 450nm, the optimum wavelength for the treatment of hyperbilirubinemia. A cosine corrected diffuser input assembly ensures the radiometer responds accurately to the position and angle of the light sources.

  • Air Actuators

    Del-Tron Precision, Inc.

    Del-Tron's linear air actuators (also referred to as linear actuators) are pneumatically actuated crossed roller slide assemblies controlled by a pair of Airpot air cylinders which provide extremely low friction and stiction characteristics. A light touch or physical obstruction will stop the unit’s movement to prevent damage to delicate and expensive equipment and parts. Low pressure operation is possible. The PNRE series requires less than 10 psi to operate.

  • 14.2mm (0.56") Digit Height

    SP 8-100 - Lascar Electronics Ltd

    The SP 8-100 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user selectable. The SP 8-100 features a negative rail generator which enables the meter to measure a signal referenced to its own power supply 0V. The bright red LED display ensures excellent readability under low light conditions

  • 2U/3U Loads chassis

    H73003200 - 6TL Engineering

    This chassis can be customized depending on the specifications of the DUT, providing a simple and cost effective solution when loads are needed in your test strategy. Its limitation, due to the rigidity of the load values is compensated by the easy substitution of the chassis for another one with a different configuration. The loads rack can combine resistors with inductances and capacitor, or even active loads to, for instance simulate the thermal behavior of a light bulb filament.

  • AC Voltage Detector w/ Adjustable Sensitivity

    9601 Sniff-It 2 - Triplett

    Detects AC Voltage without making contact. Variable Sensitivity, from 5 to 600 Volts AC. Light flashes & beeper chirps when AC voltage is present. Flashes & Beeps faster as AC voltage is approached. Economical, Non-Contact probe is safe and simple to use. Pocket-Sized. Power Beeper Reminder. Powered by one A23 Battery (included). 5 year warranty.

  • Advanced AC Filtered Tone and Probe Kit

    Pro220K - Armada Technologies

    The Pro220K tone generator and probe kit is designed to help contractors easily identify the termination point of any wire. Tone and probe technology has been around since the 1970's, but not like this. Advanced features including AC filter noise rejection, headlight, low battery light, combination metal/plastic tips, etc. make the Pro220K one of the most advanced tone/probe kits ever. Uniquely, the Pro220K uses AA batteries, providing tremendous battery life.
