The Model ConST116 Pneumatic Hand Pump is a dual pressure source with the ability to easily adjust and stabilize. This calibration pump possesses both 95% vacuum and pressure 375psi; 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), ConST116 is totally free from humidity and dirt. Because ConST116 is airtight and durable, it is entirely better than other pliers hand pumps more much. The adjusting resolution is up to 0.01 Pa (0.0001 mbar). These features make the CONST116 ideal for calibrating pressure transducers, precision pressure gages, and other pressure instruments. The patent right number of ConST116 is ZL 2008 2 0123201.0, const group reserved.
