Confined Space Gas Monitor

When dangerous levels of VOCs may be present in a confined space, it is important to verify the concentrations to ensure worker safety. A photoionization detector or a flame ionization detector can be used as a confined space gas monitor to alert the operator of hazardous conditions. It is important for a Confined Space Gas Monitor to be intrinsically safe for operation in areas in which hazardous concentrations of VOCs may be present.

What instruments can be used as a Confined Space Gas Monitor?
The Photovac 2020ComboPRO PID is ideal for use for this application. This handheld photoionization detector has built in alarms that alert the user of dangerous concentrations. Additionally, the DataFID utilizes flame ionization technology, and therefore can detect a wider range of VOCs, including methane.

What are important characteristics to consider about a Confined as Space Monitor?
For an instrument to be effective as a confined space gas monitor, it should be small, compact and easy to use. Hand held instruments are the most convenient to operate in a confined space situation. An instrument needs to provide rapid response, to alert the user in time about potential dangers. Also, a confined space gas monitor should be intrinsically safe to operate in a hazardous situation, in case high levels of VOCs are present.

When should a flame ionization detector be used as a confined space gas monitor?
An FID should be used when the compounds that are potentially present are not detectable by a PID. In petroleum confined space situations, an FID will respond best to the Aromatics, Alkenes and Alkanes that may be present.

How long will the unit work on a full battery charge as a portable unit?
The 2020ComboPRO will operate for approximately 8 hours on a fully charged battery. The DataFID's long life battery enables it to operate for 15 hours on a single charge.

How reliable are the instruments?
If the instruments are properly maintained they are accurate and reliable in a range of environmental conditions, including high humidity..

Does Photovac provide a warranty on the units?
Photovac provides a one year warranty on all of its products for defects in material or workmanship.
