Detailed Description of Items: CLIN 0001: The new calibrators for Regions 4, 8 and 10 must meet the following specifications: ? Provide programmable microprocessor control of continuous, real-time dilution of up to 4 external compressed gas cylinder sources of CO, SO2 and NO or NO2 with externally provided, pressurized Zero air; ? Provide the largest dilution and zero air capacity possible, as a part of the equipment overall design; this is currently 30 SLPM; and the smallest capacity (10 cc/min) for the blended pollutant gas; plus 100cc/min for regular range audit gas concentrations. ? Provide for mixing and reaction of the NO with internally-generated ozone to dynamically produce NO2 according to EPA requirements for Gas Phase Titration (GPT); ? NIST-traceable accuracy of concentration and flow, and repeatability from 10-100% of full scale, of +/- 1.0%; ? Non-reactive flow path surfaces (for example, teflon tubing, stainless steel mass flow controllers, Viton seals); ? Maximum weight of 40 lbs; ? Provide ozone generator which has built-in temperature-control, pressure compensation, and includes a precision optical feedback circuit to compensate for lamp aging; ? Ozone Generator Concentration Range of 0.5-1.25 ppm at 10 slpm, accuracy of +/-2.0% or +/- 0.005 ppm at 10 slpm, and 30 day repeatability of +/-2% or +/-0.005 ppm; ? Comes with rack mount feature; ? Contains an internal, adjustable ozone generator that provides 1 to 20 L/minute flow rates; ? Mass Flow Controller warm-up time of 30 minutes, response time of 30 seconds to +/-2.0% of set point ? RS-232 Serial Data Interface



CLIN 0002: The new calibrator for the alternate test method that will be tested by Region 2 must meet the following specifications: ? All flows going through the mass flow controllers (MFCs) prior to any ozone generation; ? When configured with three MFCs, can have any output assigned to each of the flow controllers in question. ? The serial outputs can be polled and the flow controller readings can be data logged. ? One (1) 20 SLPM dilution gas mass flow controller ? One (1) 100 SCCM span gas mass flow controller ? One additional 10 SCCM circuit with: Mass flow controller, solenoids, control electronics & tubing ? Mass Flow Controller warm-up time of 30 minutes, response time of 30 seconds to +/-2.0% of set point ? Loop plumbing on output of MFC?s. ? One (1) Dilution Gas Inlet Port ? Four (4) Span Gas Inlet Ports ? Ozone Generation Module, reaction chamber and electronics for ozone calibration and gas phase titration ? Provide ozone generator which has built-in temperature-control, pressure compensation, and includes a precision optical feedback circuit to compensate for lamp aging; ? RS-232 Serial Data Interface (Terminal/Printer Computer/Modem) ? I/O control (8 inputs / 8 outputs) programmable through software ? Portable configuration ? All Teflon tubing ? Rack mountable case
