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

Accessories

  • Gas Interconnect: When used in conjunction with the SEMTECH-FEM, the interconnect joins the 2 analyzers through a manifold, eliminating the need for additional pneumatic lines.
  • Dust Filter: A standard Briggs & Stratton air filter is fitted into the filter box on the rear of the unit.



Options

  • Low CO Optical Bench: Coming soon
  • Vehicle Interface: Vehicle network data is obtained through the vehicle interface, recording important vehicle parameters along with the emissions data.
  • Enhanced Accuracy GPS: The GPS receiver tracks the route taken by the vehicle under test, recording signal quality, date, time, latitude, longitude, altitude and speed.
  • Weather Probe: The plug-and-play weather probe provides accurate humidity readings used in the emissions calculations.
  • Shock Mount Plate: This custom designed shock mount plate protects your equipment by absorbing the inevitable vibrations that come with in-use testing.
