Additel ADT912A-N2 Pressure Test Pump
Overview
Unlike pumps that rely on a check valve, the ADT912A uses an insulated isothermal chamber with specially designed bellows so pressure stays stable even when ambient temperature changes or the unit is handled. A shut-off valve closes the air in the chamber during calibration, and a built-in gas-liquid isolator protects the pump from moisture and dirt.
Two hand-tight quick connectors, 1/4 in NPT female, accept the reference gauge and the instrument under test without tools or PTFE tape. The ADT912A-N2 configuration supplies dual 1/4 in NPT hand-tight connectors on the compact 2.8 kg frame.
Features
- Generates 95% vacuum to 60 psi (4 bar) with air
- Isothermal bellows chamber for excellent stability
- Screw-press fine adjustment for micro-pressure control
- No check valve, so pressure holds when touched
- Shut-off valve locks pressure during calibration
- Built-in gas-liquid isolator reduces maintenance
- Hand-tight 1/4 in NPT quick connectors
- Portable at only 2.8 kg
Applications
- Calibrating pressure gauges, transmitters and switches
- Low-pressure and vacuum comparison testing
- Field and workshop pressure instrument checks
