Electronic Control Unit
The requirement of all bladder and gas drive pumps to have time-adjusted drive and vent cycles is greatly simplified due to the tested preset modes used in the Electronic Control Unit. First time users can have their pump operating efficiently in minutes. Easy operation of timers and pressure allow more experienced users to fine tune samplings with minimal adjustment.
The Solinst Electronic Control Unit controls the supply of compressed gas to pneumatic pumps. The Control Unit uses 8 AA batteries, that can be easily replaced in the field, allowing continuous operation for up to 30 hours.
Simple, preset sample modes allow easy selection of the desired sample rate. The sampling rates may be selected to ensure a representative low-flow sample at 100 ml/min or less, or higher flow rates for purging may also be chosen.
