Extensive use, more than you can imagine

Built-in RS485 interface, GS1 supports multiple probes that can be used in various industry fields. The large and clear LCD screen supports display of the external probe readings in order when more than one probes connected. Altogether 4 probes can be connected at a time, one of each type. Please avoid using TH30S-B and CO2 probe at the same time because they are not compatible.
