The Model 464 Electronic Control Unit from Solinst Canada Ltd. is designed to work easily with pneumatic pumps to provide ground water samples. It outputs 125 psi and uses four AA alkaline batteries that last up to 100 hours of normal use. It is fully automatic with preset sample modes, but the controller also can be operated manually. The unit helps allow faster purge rates and precise low-flow control to ensure a representative sample at 100 ml/min or less when sampling for VOCs. It is suitable for use with Solinst Model 407 Integra Bladder Pumps and Model 408 Double Valve Pumps.
