The 466 Electronic Control Unit controls the supply of compressed gas to pneumatic pumps including the Integra Bladder Pumps and Double Valve Pumps. The Control Unit uses simple, preset sample modes to allow easy selection of the desired sample rate, with controls for further finetuning. The sampling rates may be selected to ensure a representative low-flow sample at 100 ml/min or less. Higher flow rates for purging may also be chosen. The Electronic Control Unit is available in 160 psi and 250 psi models. The Controller uses 8 AA batteries, that allow continuous operation for up to 30 hours, and can be easily replaced in the field.

The 12 Volt Compressor is lightweight and compact, ideal for field use. It uses any 12 volt DC power source, such as a car or truck vehicle battery, and comes with alligator clips. The compressor operates at 125 psi and is equipped with a 2 US gallon (7.6 liter) air tank which is rated to 150 psi.
