Dry nitrogen is capable of reducing the humidity in the chamber to
less than 1% RH, but due to mechanical considerations the lower
limit of the chamber is specified at <5%.
This system is similar in operation to the controlled valve described
in Package D. The only operational difference being that it has an
AC (specified 115 or 230VAC required) instead of a DC operated
solenoid and is controlled by the Model 5112 Controller instead of
the built-in fixed-point control.
