IQ+FLOW® Ultra compact Pressure Meters / Controllers

Microfluidic Forward Pressure Controllers

Bronkhorst^® model IQPD-600C Forward Pressure Controllers are miniature devices which are ideal for use in cramped environments or in systems requiring minimum internal volume e.g. desktop equipment. The downported Pressure Controller has a chip-based (MEMS) sensor and is suited for pressure ranges between 0,025…0,5 bar and 0,5…10 bar absolute or gauge. Communication with the devices can be either in analog mode or digital over RS232 or RS485.

The ultra compact IQ⁺FLOW instruments are typically recommended for integration in analytical, bioprecessing and medical equipment.
