NO / NO2 Gas Analyzer

NO / NO2 Gas Analyzer



Order

Description

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.


Feature

  • 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 240 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.
  • Rugged Construction: The unit can be used in harsh environments, including, for example, off-highway testing.
  • 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
