  • Solar Cell Testers

    Photo Emission Tech., Inc.

    Solar Cell Testers are integrated systems incorporating Solar Simulator and I-V Measurement systems. PET offers Standard and Advance IV Measurement software. PET Cell Testers are capable of measuring a diverse range of solar cell parameters such as Isc,Voc, Imax,Vmax, Pmax, FF, Rsh, Rs and η cell conversion efficiency, complete light and dark I-V curves. All that needs to be done to test a cell is to load the cell, make electrical probes contact and press “Measure” icon on the I-V Measurement System software. The software will automatically open the Solar Simulator shutter, perform the test and close the shutter after the test is complete. The design is modular in nature and can be easily upgraded. Some options can added at a later time.

  • Surveyor Thickness Gauge

    Multigauge 5650 - Tritex

    The Multigauge 5650 Surveyor Thickness Gauge is a simple, robust ultrasonic thickness gauge designed specifically for ship and small craft surveyors, but can also be used in applications where different measurement modes are required. The user has a choice of Multiple Echo, Echo to Echo or Single Echo to cover all requirements. The gauge can be used for metal, GRP or plastic measurement and it automatically switches modes and settings depending on the type of probe fitted. The easy to use keypad on the Surveyor Thickness Gauge allows operator interface whilst the bright LCD display can be used in all light conditions. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge at the same time as transmitting recognition data the result is a perfectly matched probe and gauge for enhanced performance. Additionally, the Automatic Measurement Verification System (AMVS) used with multiple echo ensures only true measurements are displayed, even on the most heavily corroded metals.

  • Cable Tester, Tracer, Tone Generator, Network tester

    PR-68 TestAll - Pansco, Ltd

    The Testall is an attempt to put together in a small package all the features a professional or amateur working with network cables might need.
