Ultra-Low Range Gas Filter Correlation Carbon Monoxide Analyzer
Model T300U
The Model T300U Trace-level CO analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. Using IR absorption with a Gas Filter Correlation Wheel, the T300U is designed to allow ultra-sensitive CO measurements while still meeting the requirements for use as a US EPA compliance analyzer.The optical bench is enclosed in a temperature controlled oven, dramatically decreasing instrument noise and drift. The objective and field mirrors in the sample cell are gold plated to maximize signal to noise performance, while a temperature-controlled Nafion dryer on the inlet minimizes water interference caused by ambient humidity changes. Periodically, the T300U seamlessly corrects its baseline by routing the sample through a heated catalytic CO scrubber. This Auto Reference function corrects zero drift and reduces the effect of interferences.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300U comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Short Circuit Test System
Shanghai Guantu Technology Co., Ltd.
The short-circuit test system refers to what kind of short-circuit test is carried out by which equipment, and how long is the test time. But I have one thing to tell you, the short circuit test is a kind of destructive test, mainly to test the working condition of the used equipment in a crisis situation, or to test how strong the anti-destructive ability of the used equipment is. Just like a lot of equipment in the military must undergo a short-circuit test, some for 3 minutes or longer, in order to resist breaking calls against the enemy during wartime.

Gyroscopes
A device consisting of a wheel or disk mounted so that it can spin rapidly about an axis that is itself free to alter in direction. The orientation of the axis is not affected by tilting of the mounting; so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.

Platforms
The use of switching systems to route instrumentation and stimulus signals to appropriate test points on a unit under test has a very crucial role to play in most electronics test systems. The sharing of test resources, connection of calibration references, load management, and many other functions are all managed by the switching system, the switching system acts as the interface between the unit under test (UUT) and the test equipment.

PC-Based Time Interval Analyzer
GT658PCI
GuideTech’s GT658PCI is an ultra-fast, high resolution, DC – 400 MHz Time Interval Analyzer (TIA), ideal for most PC-based lab bench (timing) test applications. What makes the GT 658 superior to traditional counters is analogous to the difference between volt meters & digital scopes. While both measure voltage, the scope provides much more information about the dynamics of the signal. This is because our patented TIA substantially increases measurement speed, and the measurements are displayed as afunction of time. All of these features, along with the benefit of ‘continuous time correlation to a common reference between all measurement time stamps,’ enable our TIAs to make measurements that weren’t previously possible with traditional counters.

NplusT
NplusT was created in December 2002 by Tams Kerekes' 20-years experience in the field of electrical semiconductors and reliability testing.The company started with the sales representation of semiconductor equipment and consumable suppliers. In the meantime, qualified engineering services, linked to the represented products, were provided in Europe.In 2003 NplusT started to market "RIFLE", the non-volatile memory engineering tester, and related services. In a few years, this product has become a reference platform for many memory makers.In 2005 Liliom Laboratories, a Hungarian software development company, merged into NplusT. Thanks to this operation, the company became leader in the test data collection and processing segment.From 2008 a dominant portion of NplusTs turn-over derived from licensing software products. Today almost every European along with several Far East semicon companies license our software products and make use of qualified engineering services.From 2011, NplusT provides turn-key solutions for device testing and characterization, including hardware, software and support.
