40 ppm Methane equivalence (ppm), or 13.33 ppm Propane equivalence. These are two of the ways that the hydrocarbon concentration can be expressed. The Signal Dual FID SOLAR will always output methane equivalence. Combustion exhaust gases normally contain some hydrocarbons that are liquid at ambient temperatures.

Operation Services Signal Group Ltd assumes that the user has a certain level of understanding of gas analysers. Some aspects of gas analysis can be dangerous without proper training and understanding. Signal and its representatives are able to provide full analyser training on request. Contact your local representative for further information.

Dirty Filters may contain corrosive compounds. Use gloves. Obey local safety measures. Signal recommends and supplies PTFE filters (Part number FILT/023) for use as internal Sample filter in all Solar and Quasar instruments. These PTFE filters may be cleaned and re- used.
Page 35
The following replaceable filters are located inside the instrument and should be changed at routine service intervals, or when contaminated: ‒ Air filter: Signal Part Number FILT/029 (see Figure 12- Filter details, detail “A”) ‒ Fuel filter: Signal Part Number FILT/702 (see Figure 12- Filter details, detail “B”) Take care not to damage the plastic filter body when replacing.
