Pneumatic Hand Pump

Operating Instructions

The MECP500 Pneumatic Hand Pump is a compact, lightweight,
portable, hand-operated pressure and vacuum pump. When a digital
calibrator is added the unit can be used to calibrate or check
pressure measuring devices in the field. No external power or high
pressure bottles are required. The MECP500 is completely
assembled and ready to connect to the pressure device to be
calibrated. Calibration is quick and simple since the pump is taken
directly to the pressure device. This pneumatic pump provides a
source of air pressure, 0-500 psig (600 psi max.), or vacuum,
0-28" Hg.
