This is my super awesome description for this amazing product. It includes cool features and amazing things this product is capable of! This description should be well written, short, and super helpful for the customer.

The GE Druck PV411A Four-In-One Hand Pump is the ideal field tool for applying test and calibration pressures to sensors, gauges, switches, indicators, and recorders. The GE Druck PV-411 A is also a low-cost pressure source for workshops and laboratories. This wide capability removes the need to carry several hand pumps. Vacuum Applying a vacuum to absolute, negative gauge, and differential field instruments is no longer a problem. With just a few strokes, the Druck PV 411A generates up to 95% vacuum (-950 mbar at 1000 mbar ambient).

The GE Druck PV 411A is a high-quality, field proven pressure and vacuum hand pump providing functionality, which has never been seen before in a handheld pressure source. This remarkable product replaces four conventional hand pumps and offers the following additional features:

• Pressure/Vacuum selector valve also provides exceptional fine control pressure relief in both pneumatic and hydraulic modes
• Tamper proof adjustable overpressure protection valve which can be set to relieve pressures from 300 to 10,000 psi
• Removable hydraulic reservoir which can be disconnected from the pump without draining the fluid
• Reservoir safety feature with spring loaded top cover vents if inadvertently pressurized above 8 psi
• Hydraulic mode designed to operate with distilled water and/or high viscosity mineral oil
• A highly sensitive volume adjuster is used for hydraulic, pneumatic, vacuum and low-pressure operation
• Built-in stroke adjuster controls the pressure/vacuum generated per stroke
• 240° swivel head for optimum viewing of reference indicators
• Internal moving parts are PTFE anodized for reduced friction and wear
• Ergonomic, rugged, and lightweight design with comfortable hand grip

The revolutionary PV 411A (4 In 1) multi-function pressure generator is a remarkable new hand pump for generating vacuum, gas, and hydraulic pressures from a few mbar up to 700 bar. It replaces four conventional hand pumps and sets the following new standards of performance:

• Vacuum: to 95%
• Low pressure (gas): 0.1 mbar resolution
• Medium pressure (gas): to 60 bar
• High pressure (hydraulic): to 700 bar

GE's DPI 104-IS is an intrinsically safe version of the microprocessor-controlled DPI 104-digital pressure gauge. The pressure gauge matches advanced silicon sensor technology with several convenient design features, resulting in an accurate and versatile, yet affordable safe digital test gauge. Supplied as a stand-alone process indicator or in a kit with the widely proven Druck hand pumps, the DPI 104-IS provides a reliable and economic solution for a wide range of pressure sensing applications.
