Portable refrigerator freezer to maintain the reagents contained in the impingers at low temperature thus prolonging the efficiency over time. Via the quick couplings placed in inlet and outlet, the refrigerator can be connected with the entire sampling line (pump, the sampling probe and any traps).

Internally it is already prepared to accommodate the required impingers (type A) for sampling.

Can also be used for the transport of the samples with the ability to feed it from the car battery.
