DM-334 is a laboratory gas control system from Labfacility, a company that specializes in industrial gas and oil technology. It is a fully automated system designed for controlling and measuring the pressure, temperature, and flow of gases in industrial and laboratory applications. The DM-334 consists of a PLC (Programmable Logic Controller), a display panel, an interface module, and an anemometer to measure air velocity. The PLC is designed for controlling multiple simultaneous gas processes, while the display panel enables the user to program and monitor the system. The interface module provides communications between the PLC and the measuring instruments, allowing for communication with a variety of devices. The anemometer measures air velocity, and it can be used to accurately measure gas flow rates. The system can be configured to support various connection types, such as a network, serial, CAN Bus, and Digital IO.
