The Model ConST117 Portable Pneumatic Pump is a dual pressure source with the ability to easily adjust and stabilize. This calibration pump possesses both 95% vacuum and pressure 600psi; uses air as the media, and can adjust the pressure easily and stably. Since it is attached inner gas-liquid isolator and shut-off valve (for releasing dirt), ConST117 is totally free from humidity and dirt. Because ConST117 is airtight and durable, it is entirely better than other pliers hand pumps more much. The adjusting resolution is up to 10Pa (0.1 mbar). These features make the CONST117 ideal for calibrating pressure transducers, precision pressure gages, and other pressure instruments, especially for big cavity pressure gauge.
