All devices will degrade with time. Add environmental variables and this will increase the degradation rate.
The Eye-One Display 2 under ideal circumstances should last about 4-5 years. Even though the i1d2’s internal components are encased, it’s not a perfectvacuumseal. Oxygen, pollution, gases, chemicals, heat, and moisturecan degrade the filters and internal components faster (of course).
It is advised (for longevity and stability) to store measurement devices in a stable environment away from the variables that affect it negatively (or at least minimize these).
You can store the i1d2 in an area with adehumidifierwith positive benefits and no downsides that I know of.
