Model MGC 101 LCD Computerized Multi-Gas Calibrator Brochure

CALIBRATIONComputerized multi-gas calibratorModel MGC 101 LCDDescriptionThe MGC101 consists of a singlechassis supporting 2 thermal massflow controllers, an ozone genera-tion module, a mixing zone, a reac-tion chamber for gas phase titration,and control electronics.The mass flow controllers are cali-brated to a NIST (National Instituteof Standards and Technology) tra-ceable primary standard. The cali-bration data consists of a compari-son of desired versus actual flowover the full dynamic range of theinstrument with linear interpolationbetween points. Calibration data isstored in non-volatile memory andmay be updated by the user with asuitable standard.The MGC101 ozone generator isfactory calibrated using a NIST tra-ceable ozone standard. This tempe-rature controlled, ultra-violet (UV)based ozone generator includes aprecision photo-optical feedbackcircuit to compensate for lamp agingeffects.The MGC 101 is available in either astandard rack mount or portableconfiguration.Applications• Air quality monitoring stations and mobile laboratories for manual, auto-matic or remote calibration•Used as a reference calibratore in central station.• Test of analyzers : Automatic zero, precision, span, multi-point calibrationand gas phase titration (GPT).Main features and benefitsExceeds all U.S. Environmental Protection Agency requirements.• User-friendly interactive software with plain language prompts is simple to use, reducing technician training time and virtually eliminating error. • Automatic calculation of dilution and span gas flows based on commanded concentration eliminates the need for manual computation and allows rapid transition from point to point. • Internally-stored mass flow controller calibration data improves accuracy by as much as a factor of ten and simplifies field recalibration.• Internally-stored ozone generator calibration data insures linear, repeatable ozone generation without photometer control. Ozone generator performance exceeds U.S. EPA criteria for ozone transfer standards. • Ozone generator pressure compensation ensures repeatable ozone generation at a flow rate and back pressure other than that at which it was originally calibrated• Full, two-way RS-232 Serial Data Interface (standard) permits remote operation of the instrument including data collection, gas selection, initiation of zero, span and multi-point calibrations.

GB 1CALIBRATION• Blend: In response to software prompting, user selects gasport, span (cylinder) gas concentration, output gas flow (total)and output gas concentration. MGC 101 automatically deli-veres concentrations at the total flow specified.• Generate Ozone: Allows user to specify, then generate aprecise concentration of ozone.• Gas Phase Titration: Utilizes blend and generate ozone routines tolead user through GPT using “excess NO” method.• Manual: Allows user to manually command a desired rate of flowfor each mass flow controller.• Display: Allows user to monitor flow rates for each mass flowcontroller separately, Also provides ozone oven block temperatureduring generate ozone and gas phase titration routines. • Maintain Ports: User enters the name of the span gas in the sourcecylinder, its concentration (ppm) and the port to which the cylinderis connected.Mass Flow Controller (as a percent of setpoint)*Accuracy From 10 to 100% • Concentration: ± 1.0% of FS • Flow: ± 1.0% of FSRepeatability ± 0.05%Warm up time: 30 minutesOzone GeneratorConcentration Range: 0.02 - .5 ppm at 5 – 10 slpmOptional Ranges: 0.05 - 1 ppm at 5 – 10 slpm0.1 - 6 ppm at 5 – 10 slpmOther ranges available upon requestAccuracy: ±2% or ±.003ppm 30 day repeatability: ±2% or ±.003ppmMechanicalInletsBalance: External 1/4" Swagelok™Span(s): External 1/4" Swagelok™ Distributed by : Computerized multi-gas calibratorModel MGC 101 LCDSoftwareSpecificationsOutletOne external 1/4" Swagelok™*Operating Pressures at inletsMinimum: 10 psig (0.67 Bar)Recommended: 25 psig (1.68 Bar)Maximum: 50 psig (3.44 Bar)Wetted SurfacesTubing: TeflonTMMFC's: Stainless SteelSeals: VitonOperating temperatures: 0°- 50° C (32°- 122°F)Performance Temperature Range: 15° - 35° C (59° - 95° F)WeightMinimum: 10 Kg (20 lbs).
