  • Photolytic True NO2/NO/NOx Analyzer

    Model T200P - Teledyne Advanced Pollution Instrumentation

    The Model T200P provides measurements of NO and NO2 using our Model T200 NOx analyzer combined with a patented high efficiency photolytic converter. Even low temperature molybdenum converters transform other nitrogen-containing compounds such as HNO3, PAN, etc. to a considerable extent. Simultaneous measurements of NO2 performed with molybdenum and photolytic converters have shown significantly different results in the presence of such compounds.In the photolytic process the sample gas passes through a cell where it is exposed to light at a specific wavelength from an LED array. This causes the NO2 to be selectively converted to NO with negligible interference from other gases. Advances in the photolytic converter technology now yields NO2 conversion efficiency that is similar to molybdenum under typical ambient NO2 concentrations, but without the same interferences.

  • PXI Switch - 16-CH General-Purpose SPDT Relay Module

    PXI-7901 - ADLINK Technology Inc.

    ADLINK PXI-7901 is a general-purpose (GP) switch module implementing 16-CH independent single-pole double-throw (SPDT) relays (1 Form C). PXI-7901 can connect one input to one output and be used as signal switching and routing for measurement system or ATE. Thanks to its high switching capacity, PXI-7901 can also be used to turn on or turn off devices such as motors, fans, heaters, and lights. The contact position of the relays can be changed either by direct software commands or by following the instructions previously stored in the on-board scan list. The scan list advances upon the trigger from external measurement devices, such as a DMM. The scan list could also advance when the scan-delay timer expires. In the PXI-7901, PXI trigger functions are supported and software programmable. Multiple modules can therefore be synchronized without additional field wiring.

  • Laser Spectroscopic Motor Exhaust Gas Analyzer

    MEXA-ONE-QL-NX - HORIBA, Ltd.

    The MEXA-ONE-QL-NX is an analyzer for the direct, simultaneous real-time measurement of the four relevant nitrogen-containing exhaust gas components NO, NO2, N2O and NH3.The analyzer combines a light source based on the new quantum cascade technology (efficient lasers in the mid-infrared spectral region) with a precisely adjusted dual path cell to measure low concentrations with maximum sensitivity. The detection limit complies with current European legal requirements.Furthermore, the MEXA-ONE-QL-NX offers wide measuring ranges of up to 5000 ppm (for NO). By using extremely narrowband light sources and measuring under reduced pressure the cross-sensitivity to other exhaust gas components can be drastically minimized.The complete measuring system - including filtration - is specifically developed for the measurement of NH3 and thus guarantees a very fast NH3 rise time (T10-T90) of less than 5 seconds. The MEXA-ONE-QL-NX can be operated as a stand-alone analyzer or integrated into the MEXA-ONE software interface for user-friendly and simplified system operation.
