The Additel 901A Low Pressure Test Pump is hand-operated and designed to generate pressures from -6 psi (-0.4 bar) to 6 psi (0.4 bar). It’s got a high-quality screw press that’s designed for fine pressure adjustment with an adjustment resolution up to 0.1 Pa (0.001 mbar). Ultra-stable and ultra-precise, the 901A uses an isothermal bellows chamber that’s designed to reduce the effects of environmental temperature change and doesn’t use a check valve like other pumps. No check valve means more insulation, and less fluctuations in pressure when ambient temperature changes. It also has two hand-tight connectors that give you easy connection and disconnection to the test pump.

Key Features:

  • Portable — only 3.5 lbs
  • Adjustment resolution of 0.1 Pa (0.001mbar)
  • Specially designed screw press for fine pressure adjustment
  • Stable — isothermal chamber insulates pressure chamber to reduce the influence of environmental temperature changes
  • Specially designed bellows minimize leakage
  • Minimal maintenance without non-returning valve
  • Easy-to-use — pressure can be adjusted and set with turn handles
  • Hand-tight Quick Connectors allow for easy connecting and disconnecting to the test pump without the need for PTFE tape or wrenches
  • 1-year warranty
