الوصف

The Model ConST**7 Portable Pneumatic Pump is a dual pressure source with the ability to easily adjust and stabilize. This calibration pump possesses both *5% vacuum and pressure **0psi; 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), ConST**7 is totally free from humidity and dirt. Because ConST**7 is airtight and durable, it is entirely better than other pliers hand pumps more much. The adjusting resolution is up to *0Pa (0.1 mbar). These features make the CONST**7 ideal for calibrating pressure transducers, precision pressure gages, and other pressure instruments, especially for big cavity pressure gauge.
