Is there a difference between portable and stationary type samplers?
Portable samplers, are exactly that, portable. They are samplers that are easily and readily movable. They are generally battery operated, but offer the option of AC power as well. Most portables do not offer refrigeration, but can be packed with ice or cooling packs. Stationary and All Weather Samplers are usually powered with 120vac, though some offer battery power and battery backups. They are not intended to be moved frequently. They do however offer a fully refrigerated compartment. Others offer a heating package to keep the controller and sampling line from freezing during winter months.
