Microfluidic Pressure Meters

Bronkhorst® model IQPD-500C Pressure Meters are miniature devices which are ideal for use in cramped environments or in systems requiring minimum internal volume e.g. analytical equipment. The downported Pressure Meter has a chip-based (MEMS) sensor and is suited for pressure ranges between 0,01…5 bar and 0,2…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 and medical equipment.
