This device has the APP Android ASAPP (code 300) already installed. It has a display of 7” LCD. The Bluetooth connection with all TRIO.BAS™ instruments allows for the downloading of the sampling data. The PCU can also be used to remotely turn on, turn off and pause the air sampler. The data downloaded from the instruments through the PCU can be transferred to a PC when Air Sampler ASPC software is installed (i.e. by USB connection). The PCU Portable Command Unit is an ideal instrument to simplify and to facilitate the activity of operator.
