The 2240 PROcheck is a table top gas concentration measuring monitor for SO2F2. The main field of application is the continuous monitoring of the active gas concentration in pest control. The unit has three gas channels. These can be selected individually or automatically cycle through the selected channels. Thanks to a simple proprietary machine interface, the device can also be integrated into a higher-level automation system. A variety of options are available for the 2240 PROcheck, such as recording data to a USB stick or sending data to cloud storage in conjunction with a protected web portal from ppm Messtechnik GmbH.
