The air sampler can be fixed directly on the tripod or alternatively on a STAND UP (optional) for TRIO.BAS MINI (code 370), stand up holder for TRIO.BAS MONO, DUO, TRIO (code 376) or stand up holder for AIRBIO (code 377).This solution facilitates the operator's activity as the sampler can be inserted and removed from the tripod with one hand and without the constraint of screwing or unscrewing the instrument.
