Higher Flow Applications
The high flow capability of the Gilian 12 enables sampling capability for applications with flow rates between 4LPM and 12 LPM.

NiMH Memory-Free Battery
NiMH battery with quick-charge time in under 4 hours.
Eliminates shipping and disposal issues.

Programmable Functionality
• Four stage program with repeat cycling
• Allows scheduled sampling or intermittent duty cycles
• Programmable delayed start

Intuitive Operation with Lock-out Feature
Simple four-button design makes pump easier to understand and operate.

Live Flow Display
Large display continuously shows real-time flow, total sample time and total volume sampled. Special flow control circuitry automatically compensates for changes in flow rate, back-pressure and temperature.
