Mobility
EPA's Field Screening Methods Catalog uses the following terms to describe air monitoring equipment:
- Portable: Hand-held devices can be easily carried by one person and require no external power source.
- Fieldable: Easily transported in a van, pick-up, or four-wheel drive. Particularly rugged and limited external power required.
- Mobile: Small enough to carry in a mobile lab. Power consideration may limit the use of many instruments in mobile laboratories. (Size, durability, and power supply are the main considerations in determining the mobility of an instrument.)
Ease of Operation
Because many of these instruments were designed for industrial use, allowances may not have been made for using the instrument while wearing protective equipment.
One must consider how easy it is to use the instrument while wearing gloves or how difficult it is to read the meter while wearing a respirator. Also, how quickly a user can learn to operate the instrument correctly should be considered.
