About Environmental Chambers
The grips can be mounted for room temperature testing or testing in an environmental chamber. The
temperature range of the grips is determined by the type of seals used in the grips and the type of fluid used
for the grips. There are two methods for using grips in an environmental chamber (as shown in the following
figure).
