  • Concrete Water Impermeability Tester

    Qualitest International Inc.

    The concrete water impermeability testing system is designed with many different standards in mind including DIN 1048, ISO/DIS 7031, EN-12390-8 & UNI 9533. This impressive piece of machinery comes in different models with either 3 or 6 measuring points and with or without quantitative measurement of water permeability. The supporting structure is very stable and is at a convenient height to allow the easy access. The pans are made out of stainless steel, the specimens are easy to insert due to the clamping device.

  • Circuit Board Tester

    Huntron® Tracker®3200S - Huntron

    The Tracker 3200S features two 64 pin IDC connectors (one per channel) where custom cable interfaces can be used to quickly scan PCB connectors as a type of "first pass" test. If signature differences are detected then you can trace the connector pin to the component level saving you troubleshooting time. The two 64 pin connectors can be combined for a total of 128 pins and you have the ability to select any pin to be used as Common. You can also use standard IC clips and cables to easily scan standard ICs and select SOICs. Clip and cables are readily available from companies such as Digi-Key and Pomona Electronics (see FAQ below for more information).

  • Circuit Board Tester

    Huntron® Tracker® 2800 - Huntron

    The 2800 series of Huntron Tracker are designed to complement conventional test instruments in the debug and troubleshooting process. Using the proven power-off test method known as Analog Signature Analysis it eliminates the risk of further circuit damage, which often occurs when power is applied. The Huntron Trackers are suited for todays varied signal circuit cards where Analog and Digital are mixed together. The Tracker 2800's features variable range parameters resulting in over 100 combinations of voltage, source resistance and frequency. The 2800 series is a great off-line support tool for the automated Huntron Access Prober diagnostic systems. The Tracker works by applying a current-limited AC signal across two points of a component. The current flow causes a vertical signature deflection, while the applied voltage causes a horizontal deflection. Together they form a unique V/I signature that represents the overall health of the device under test. Analyzing the signature can quickly determine whether the component is good, bad, or marginal.

  • CableEye Tester Calibration Verification Board | Cable & Harness Tester

    CB50 - CAMI Research Inc. (CableEye®)

    Populated with precision resistors, it allows users to determine empirically whether the tester requires calibration. The CB50 may be used on all CableEye models. The CB50 is intended for periodic verification of tester calibration. To ensure that resistance measurements remain accurate, CAMI recommends yearly calibration. However, depending on environmental conditions and usage, testers may need calibrating more or less frequently. Certain components within models M3U, M3UH, HVX, and HVX-21 (i.e. those capable of measuring resistance) are analog components whose characteristics change slightly over time. This aging is a natural phenomenon common to all electronic components and may cause resistance measurements or gradually deviate from normal. A tester that is out of calibration will give inaccurate results. Some (maybe all) resistance measurements will be incorrect. Consequently, it may Pass what should Fail and, conversely, Fail what should Pass. In other words product yield will be contaminated due to unreliable quality.
