Monitoring gases in confined and potentially explosive situations has become increasingly important particularly in the wake of new environmental regulations. Autofim II and Autofim II GC give you the flexibility and confidence you need to detect, measure and analyze hydrocarbon gases in virtually any hazardous location from petrochemical plants and gas works to landfill sites. These versatile products cover a wide range of applications including: volatile organic compound monitoring, fugitive emissions, process control, gas leak surveying, and landfill sites.

Reliable, Fast and Highly Sensitive - The Autofim range has been engineering to provide outstanding stability. So you can always rely on the results without the need for weekly calibration. To localize leaks quickly and safely your detector must react rapidly and accurately. The flame ionization detector ensures a rapid response: within 2 seconds. Expanded scales allow you to detect and measure gases with pinpoint accuracy even at the lowest levels.

Simple to Use - Autofim is easy to use with the operator being guided by user-friendly, menu driven software. For maximum clarity the signal is displayed in both digital and analog formats plus a variable pitch audible output. Furthermore, the audible signal can be set only to trigger above an adjustable alarm level. The system can operate for over 40 hours without changing the batteries or cylinder. However, replacement of these in the field is a simple operation for remote or extended use.The backlit display allows you to take readings in tunnels, basements and other dark places without the need for additional lighting.

Unrivalled Measurement Range - Autofim covers the full range of measurement from 0 to 10,000 ppm in a convenient range of scales. The optional range extender/diluter allows measurements above 10,000 ppm as well as from oxygen depleted atmospheres.

Data Logging on Demand - Autofim II and Autofim II GC have a sophisticated data logging systems which enables you to keep a permanent data record. The memory is capable of storing 200,000 individual readings. This facility simplifies site surveying by allowing the operator to store readings in a single file as desired.

Autofim automatically measures and stores at user defined time intervals without an operator needing to be present. In this way gas concentration contours can be recorded over a period of time which is especially useful for process monitoring

The detachable infrared, fiber optic link allows data transfer to a computer for further manipulation and presentation. The software is compatible with most recognized spreadsheets enabling you to integrate Autofim data with your reports and other records.

Autofim II GC- Analyzing the Gases

Autofim II GC, with built-in gas chromatography, can not only detect gas with all the benefits of Autofim II but can also determine its composition on site.

There are many situations where it is necessary to determine the exact nature of the detected gas. Analysis is highly beneficial for compliance monitoring and essential for differentiating between natural gas and other hydrocarbons. Autofim II GC displays the chromatograph immediately, avoiding delays and cost of laboratory analysis.

Versatile - Having detected gas, a sample is stored in a holding loop. This can be analyzed immediately or later, if more convenient. After analysis the GC data is stored in memory for subsequent reference.

Wide Range of Gases - A series of high resolution, chromatography columns are available; tailored to most applications including VOC's, natural gas, gasoline vapors and landfill emissions. These can be easily interchanged, by the user, to address a variety of different site emissions.

Detailed Analysis - Data can be downloaded to an external PC for further analysis and presentation. The Integraf software package, specifically designed for Autofim, analyzes the data and displays a range of parameter including: retention times, peak identification, peak areas, methane/ethane ratios and relative concentrations. Graphical and tabular formats are available. The overlay facility allows comparisons between your sample trace and a library of reference chromatograms.
