The pressure regulator generates an accurate pressure or vacuum that can be used to drive a liquid flow at a stable flow rate. The 8-channel, highly integrated pressure controller has built-in pressure/vacuum pumps, solenoid valves, pressure regulators, a rotary valve, and pressure sensors. The system is able to simultaneously generate up to 4 independent channels to supply either positive pressure or vacuum (1 independent channel supplies 2 identical pressure outputs). This system can work as a standalone machine controlled by the front buttons and knobs, and it can also be controlled by the included computer program communicated through a TTL serial communication interface.
