Portable FID Now Available with On-Board Logging and Increased Sensitivity for Low Concentration Applications

摘要

Building on the success of the original MiniFID, the Pure, from Signal Group, represents an evolution in design for portable FIDs. Existing users will be pleased to see the familiar robust case and straightforward operation now combined with some new options for configuration including a catalytic air purifier for zero air and an on-board data logger. The standard method for generating zero air for the FID flame and zero calibration on portable models is to use a carbon scrubber cartridge. However, this is not effective for low concentrations of methane in ambient air and requires replacing on a periodic basis. Signal now offer the option for a heated catalytic air purifier instead to provide a more stable baseline and more sensitive readings when using the 0-10ppm bottom range.
