New Simple to Use Pump Control Unit for Groundwater Sampling

Solinst (Canada)  Model 464 Electronic Pump Control Unit is made to work easily with pneumatic pumps and obtain representative groundwater samples during monitoring programs such as site assessments, contaminant detection, site characterisations, remediation projects, compliance monitoring, etc.

The Model 464 is designed to help field technicians meet the sampling protocols of regulators worldwide, including the U.S. EPA. The Controller allows faster purge rates, as well as precise low flow control to ensure a representative sample at 100 ml/min or less when sampling for Volatile Organic Compounds (VOCs).

The Control Unit outputs 125 psi and runs on 4 AA alkaline batteries that can last up to 100 hours of normal use. The Model 464 also has a manual mode that allows users to operate the Control Unit without batteries, using only a compressed air source.

These convenient boxes are rugged, dependable and suitable for all environments. Tubing is supplied and quick-connect fittings allow instant attachment to pumps, dedicated pump well caps, portable pump reel units and to an air compressor or compressed gas source.
