| 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 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. Also available, for higher pumping
pressures, the Model 466 gives up to 250 psi output.
These convenient boxes are rugged, dependable and suitable
for all environments. Quick-connect fittings allow instant
attachment to dedicated well caps, portable reel units and to an
air compressor or compressed gas source. |
| The Model 464 Electronic Control Unit controls the supply of
compressed gas to pneumatic pumps. Drive (pressure) and vent
periods are cycled to provide water flow. During pressurization
periods water is forced into the sample tubing. The Vent period
allows water to re-enter (recharge) the pump. Cycle repetition
may be controlled manually or automatically using pre-set
pumping rates. |

| The Solinst Model 466 Electronic Pump Control Unit is
designed for deeper applications with preset sample modes,
providing a variety of drive and vent cycles; users can also
adjust manually for optimum flow rates. The Model 466 is designed to
work with pneumatic pumps
and easily connect to an air
supply, including the Solinst
12 Volt Compressor. Output is
up to 250 psi and 8 AA batteries
provide 30 hours of use. |
