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.

LVDS (Low Voltage Differential Signaling) Drivers and Receivers from Analog Devices offers designers robust, high speed signaling for single-ended to differential solutions for point-to-point applications. Our selection of products conform to the TIA/EIA-644 LVDS standard and contain the first LVDS transceivers to meet 8 kV IEC ESD performance standards - important for robust, interboard applications where the connectors can be exposed to more harsh electrostatic environments. Companion differential line receivers and differential line drivers support up to 600Mbps. LVDS greatly improves noise immunity and minimizes emissions for high speed point-to-point data transmission and is a low power alternative to emitter-coupled logic (ECL) or positive emitter-coupled logic (PECL) signaling.
