Thermo Fisher Scientific - Model 146i - Multi-Gas Calibrator
The Model 146i mass flow controller ozone generator, permeation tube oven, power supply and solenoid valves are integrated into a single microprocessor controlled unit. This permits easy to use menu driven software and a consistent set of operation screens for all calibration procedures. Additionally, the microprocessor can make many of the necessary calculations, thereby freeing the operator from having to make the calculations in the field or ...

Thermo Fisher Scientific - Model 42i - NO-NO2-NOX Analyzer
The Thermo Scientific Model 42i utlizes chemiluminescent technology to measure levels of nitrogen oxides (NO-NO2-NOx) in the emissions from a source. The flagship product in the Thermo Scientific iSeries line, the Model 42i is the most recognized NOx analyzer in the industry. Using chemiluminescence technology, the Model 42i measures the amount of nitrogen oxides in the air from sub-ppb levels up to 100ppm. The Model 42i is a single chamber, single ...

Thermo Fisher Scientific - Model 42i TL - Trace Level NOx Analyzer
Using chemiluminescence technology, the Model 42i-TL measures the amount of nitrogen oxides in the air from sub-ppb levels up to 1000ppb. The Model 42i-TL is a single chamber, single photomultiplier tube design that cycles between the NO, NOx and Zero modes. The addition of the Zero mode provides for excellent long term stability and extremely low minimum detectable limits. The 42i has independent outputs for NO, NO2 and NOx and each can be ...

Thermo Fisher Scientific - Model 43i - SO2 Gas Analyzer
Using pulsed fluorescence technology, the Model 43i measures the amount of sulfur dioxide in the air up to 10ppm. The pulsing of the U.V. source lamp serves to increase the optical intensity whereby a greater U.V. energy throughput and lower detectable SO2 concentration are realized. Reflective bandpass filters, as compared to commonly used transmission filters, are less subject to photochemical degradation and more selective in wavelength ...

Thermo Fisher Scientific - Model 48i - CO Gas Analyzer
Using gas filter correlation technology, the Model 48i measures the amount of carbon monoxide in the air. The Model 48i is based on the principle that carbon monoxide (CO) absorbs infrared radiation at a wavelength of 4.6 microns. Because infrared absorption is a nonlinear measurement technique, it is necessary for the instrument electronics to transform the basic analyzer signal into a linear output. The Model 48i uses an exact calibration curve ...

Thermo Fisher Scientific - Model 48i TLE - Enhanced Trace Level CO Analyzer
Using gas filter correlation technology, the Model 48i-TLE measures the amount of carbon monoxide in the air. The Model 48i-TLE is based on the principle that carbon monoxide (CO) absorbs infrared radiation at a wavelength of 4.6 microns. Because infrared absorption is a nonlinear measurement technique, it is necessary for the instrument electronics to transform the basic analyzer signal into the linear output. The Model 48i-TLE uses an exact ...

Thermo Fisher Scientific - Model 49i - Ozone Analyzers
Using UV Photometric technology, the Model 49i measures the amount of ozone in the air from ppb levels up to 200ppm.The Model 49i is a dual cell photometer, the concept adopted by the NIST for the national ozone standard. Dual range and auto range are standard features in this instrument. Because the instrument has both sample and reference flowing at the same time a response time of 20 seconds can be ...

Model 49i PS - Ozone Primary Standard
Using UV Photometric technology, the Model 49i-PS is able to produce ozone at a rate of up to 5000 ppb.The Model 49i-PS is a dual cell photometer, the concept adopted by the NIST for the national ozone standard. The Model 49i-PS can operate with ozonator flow rates of up to 6 liters a minute. Because the instrument has both sample and reference flowing at the same time a response time of 20 seconds can be ...

Thermo Fisher Scientific - Model 43i TLE - Enhanced Trace Level SO2 Analyzer
Using pulsed fluorescence technology, the Model 43i -TLE measures the amount of sulfur dioxide in the air down to 50 ppt. The pulsing of the U.V. source lamp serves to increase the optical intensity whereby a greater U.V. energy throughput and lower detectable SO2 concentration are realized. Reflective bandpass filters, as compared to commonly used transmission filters, are less subject to photochemical degradation and more selective ...

Thermo Fisher Scientific - Model 42iy - NOy Analyzer
Using chemiluminescence technology the Model 42i-Y measures the amount of nitrogen oxides in the air from sub ppb levels up to 100ppm. The Model 42i-Y is a single photomultiplier tube design that measures NOy which includes most oxides of nitrogen with the exception of NH3 and N2O. Dual range and auto range are standard features in this instrument. Because the instrument is operated continuously in the NOy mode, the response time is less than 10 ...
