Precision Dual Range Controllers allow precise control of the cycle time
and the air pressure supplied to the bladder pump. This degree of control
makes it easy to obtain a repeatable sample. Two independent air pressure
regulators with gauges are provided. The encapsulated timer module
provides accurate, independent timing of the pressure and exhaust cycles
from 0.1 to 10 seconds. The standard controller has no compressor and
requires an external air source.
Pressure Ranges: 2-50, 5-100 psig
Max Depth: 50 ft (External air source for deeper applications)
