  • Archival Storage Rooms

    Darwin Chambers Company

    Darwin Chambers Company’s NFPA, GSA, and NARA Directive 1571-compliant Archival Storage Chambers are engineered to provide maximum value, efficiency and conformance with all applicable standards and codes. Archival chambers provide environmental controls for storing records and materials (including paper documents and items with high fibrous content, various films, microfiche, and photographic materials) that require permanent protection for storage and preservation. Our high-performance systems are offered with nearly unlimited operational fail safes, includ- ing full system and control redundancy. In addition to keyed entry, numerous security options are also available, due to the often irreplaceable nature of the materials to be stored and preserved in this type of chamber. Our chambers are engineered to accommodate the loads and unique requirements of the specific materials to be stored, with industry-leading control and uniformity of both temperature and humidity variables. Design considerations include both functional and operational efficiencies and reliability, the safety and comfort of operating personnel, and the ongoing protection of the archived materials from fire, water, light degradation, pests, mold and natural contaminants, pollutants and other man- made threats.

  • CO Monitor

    AI-1200 - Airspace Monitoring Systems

    AGS with Snif technology, and now with a backlit LCD display, the 1200 monitor will accurately measure and display CO levels from 12 ppm to 250 ppm. It also includes alarms like the 1100 with a panel of flashing lights and 92 decibel audio that begins at 30 ppm and grows in intensity to 120 ppm. The Snif technology provides an update every 4 seconds when in alarm to help you find the source, see the trend and otherwise manage the CO event. Like all of our V2 models, it now has a motion switch option built into it. When motion switch management is chosen, the monitor will turn itself on by any movement and if it doesn't sense CO or hasn't moved in 45 minutes, it will shut itself off. The motion switch allows passive screening capability that can dramatically stretch your battery life without risk of forgetting to turn the monitor on or off. Like all of our monitors, there is no routine bump testing or calibration required and the monitor is warranted for five years, even the sensor and its calibration is included in the warranty.

  • Tap Changer Analyzers & Winding Ohmmeters

    IBEKO Power AB

    Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints

  • Tractor Output Tester

    Model 137 - LITE-CHECK

    Lite-Check, LLC (Lite-Check) – a subsidiary of Lite-Check Fleet Solutions, Inc. – in Spokane, WA is introducing a new product to its lineup, the Model 137 Tractor Output Tester. Exclusively availablefor purchase through Lite-Check manufacturing starting mid- January, the Model 137 Tractor Output Tester is designed to test and diagnose safety concerns between the truck and trailer and trailers towing other trailers relating to Technology and Maintenance Council (TMC) recommended practices (RP) 137C, RP 141, RP 144, and RP 619B. Most testers on the market today test the truck and trailer separately with no consideration for how they work together. The introduction of RP 137C and its revisions seeks to ensure the voltage generated by the truck is sufficient to power the ABS of the trailer while under load. With the Model 137 Truck Tester, technicians can now verify that the voltage generated by the truck meets TMC RP 137C. Similarly, trailer testing can be accomplishedverifying the voltage recommendation for additional trailer hook-ups per TMC RP 141. Also, the ability to test howthe ABS cab light responds to a trailer’s ABS ECU is incorporated into the Model 137 Truck Tester.

  • High Elongation Extensometers

    Model 3800 - Jinan Testing Equipment IE Corporation

    The main body of this unique extensometer remains stationary during testing, held in position by the adjustable magnetic base included. Only the very light, small traveling heads move as the sample elongates during a test. These attach to the sample with small spring clips. Each head pulls a cord out from the extensometer as the head moves. These models use high precision, low friction potentiometers, and, as a result, have a wide range of factory selectable outputs. The extensometer is driven by an excitation voltage and has output proportional to the input. They can be provided with high level outputs (approximately 2-8 VDC) or ones that mimic strain gaged devices (2-4 mV/V). When set to mimic strain gaged extensometers, the Model 3800 can be used with virtually any signal conditioning electronics designed for strain gaged sensors. The potentiometers employ a hybrid wire wound around conductive plastic, which provides excellent long term stability. The output from the extensometer is readily interfaced with most existing test controllers, and may be directly input to data acquisition systems and chart recorders. Please let us know at the time of order what type of output and connector you require.
