Electronic Pump Control Unit 464 (125 psi)
The Model 464 Electronic Control Unit uses 4 AA batteries and provides 125 psi output. It is fully automatic with preset sample modes from low through high flow settings. In addition, up to 99 unique user-created flow rates can be saved in FRAM memory. The Controller can also be operated manually, which means that even if your batteries run out while you are in the field, you can still obtain a groundwater sample with your compressed air source. The 464 Controller allows faster purge rates and precise low flow control to ensure a representative sample at 100 ml/min or less when sampling for VOCs.

For higher pumping pressures, use the Model 466 Pump Contrl Unit which gives up to 250 psi output.
