NOx: NO / NO2 Gas Analyzer

The analyzer meets the latest 2010 US EPA standards for vehicle emissions measurements, as defined in CFR40 part 1065, enabling laboratory grade measurements in a package that is rugged enough for both laboratory and in-use data collection.

Features 1065 Compliant: The SEMTECH-FID meets the US EPA 1065 compliance requirements for in-use testing. Signal to Noise: The LED light source can be operated at very high frequencies, enabling an excellent signal to noise ratio. 6 Temperature Controlled Zones: Six temperature controlled zones ensure accurate data throughout a wide range of ambient temperatures with minimal drift. Optimized Signal Processing: Pre-amplifiers and ADC converters are designed to optimize dynamic range and resolution. This enhances longevity in regards to sample cell contamination and normal UV source aging. Sample Conditioning: When used in conjunction with the SEMTECH-FEM, the sample is filtered and cooled prior to analysis, minimizing contamination of the analyzers. Graphical Panel Display: A full color, graphic touch screen displays live data, and enables system setup and basic functions, such as zero and span. Power Supply Monitoring: Power can be either 12 VDC, 110 VAC, or 220 VAC, with both current and voltage monitoring. Dual Ports: Sample, air and exhaust ports are located on both the front face of the analyzer, and on the bottom. The bottom ports connect directly to the intake manifold of the SEMTECH-FEM, for a fast, simple connection of the two units. Front ports are available for the stand-alone configuration. Weatherproof Construction: All components meet IP54 (NEMA 3) standards. Shock Resistance: The mechanical design has been optimized for resistance to shock and vibration, ensuring data in the most rugged of in-use environments. Design Details: Over a decade of experience in in-use emissions testing has gone into the design details of the SEMTECH ECOSTAR system, including: EMI protection, including gaskets, filters and capped connectors Stress relief for pneumatic connections Channels for cable management Standard Swagelok™ bulkhead connectors Rugged Deutsch connectors for power and auxiliary connectors Handles that lock to other SEMTECH ECOSTAR modules for stable system integration
