Flame Ionization Gas Detector
The Flame Ionization Gas Detector (FID) is similar to the PID Detector in that it provides an accurate measurement of the total amounts of VOCs present, but it is able to measure a wider range of VOCs than the PID detector. It is especially useful as a natural gas, or methane, detector. A Flame Ionization Gas Detector is often used as a HAZMAT VOC detector, especially by First Responders, as a confined space gas monitor, and for Leak Detection and Repair (LDAR).
Photovac offers two FID products, the EnviroFID and the DataFID.
The EnviroFID is useful as a detector for environmental monitoring applications. The EnviroFID is useful for detemining total VOC concentrations when methane is present. This is a gas which cannot be detected with a photoionization detector.
The DataFID has many advanced features, including Bluetooth connectivity for wireless download to a PDA or laptop, and a unique 70 hour hydrogen cylinder. The DataFID was designed for Leak Detection and Repair (LDAR) and environmental monitoring. The DataFID is rated intrinsically safe, so it can be used in hazardous environments.
The DataFID is certified to meet the UL requirements of Class 1, Division 1, Groups A, B, C and D, and the equivalent ATEX requirements.
Can I use these units as a soil gas analyzer.
Both of the Flame Ionization Gas Detectors measure methane and gas accurately, so they are ideal for soil gas analysis.
Both Photovac Flame Ionization Gas Detectors will operate for 15 hours on a full battery charge.
If they are properly maintained the instruments are accurate and reliable in a wide variety of environmental conditions including high humidity.
Photovac provide a one year warranty on all of its products for defects in material or workmanship.
