Low-flow sampling pump

20mL - 500mL

Instrument comes with 1m tube, field guide and calibration certificate


Product Overview

The VAPex range has been designed particularly for low flow sampling of vapors and gases in working environments. Its Intrinsically Safe design and remote operation via the Airwave App makes it ideal for modern-day sampling requirements. With a wide flow range of 20mL - 500mL, the VAPex personal sampling pump has outstanding back pressure capability. This capability ensures a uninterrupted smooth operation of the pump in even the most demanding situations.

Do not worry about battery life either. The VAPex pump has a high performing Li-Ion battery with an indicator on the screen showing the remaining battery life. At optimum use of 200mL/min (20cm H₂O Back Pressure), the battery lasts beyond 34 hours.

The VAPex pump has one of the most practical, slim and lightweight cases designed with user convenience in mind. The wearing clip comes with a lifetime guarantee.
