The internal, motorized pump provides an easy, efficient alternative to time consuming, tiring hand pumps. For applications that involve filling a large volume with pressure, this instrument allows for connection to an external gas supply such as compressed plant air. The pressure can be fine-tuned using the variable volume.

Features

• Measure and generate pressures from vacuum to 2 MPa (300 psi, 20 bar)
• Internal pump can generate vacuum to -80 kPa (-12 psi, -0.8 bar) or pressure to 2 MPa (300 psi, 20 bar)
• Supply pressure connection allowing the use of external gas supply up to 2 MPa (300 psi, 20 bar)
• Includes variable volume for fine adjustment of pressures
• Pressure measurement accuracy of 0.025% reading ±0.01% FS
• Electrical measurement and 24 volt supply for close looped calibrations
• Measure or generate 4 to 20 mA
• Measure 0 to 30 V DC
• Powered by internal, high capacity, NiMH battery or universal ac mains adapter
• Compatible with the 700P Pressure Modules
