Model 464 Simple to Operate Pump Controller

The New Model 464 Electronic Control Unit is designed to work easily with pneumatic pumps, including Solinst Model 407 Integra™, Model 408 Double Valve Pumps,and Bladder Pumps to provide high quality groundwater samples.  

Model 464 outputs 125 psi and uses 4 AA alkaline batteries that last up to 100 hours of normal use.  It is fully automatic with preset sample modes and can save up to 99 user-created flow rates.  The Controller can also be operated manually, with only a compressed gas source, if your batteries run out in the field.

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 and deeper applications, the Model 466 Electronic Control Unit 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 pump reel units and to an air compressor or compressed gas source.
