rubber.
This compound was chosen for its resistance to temperature
extremes, moisture, and UV degradation. However, this
jacket will support combustion in air. It is rated as slow
burning when tested according to U.L. 94 H.B. and will pass
FMVSS302. Local fire codes may preclude its use inside
buildings.

7.1 Siting
Sensors should be located over an open level area at least 9 m (EPA) in
diameter. The surface should be covered by short grass, or where grass does not
grow, the natural earth surface. Sensors should be located at a distance of at
least four times the height of any nearby obstruction, and at least 30 m (EPA)
from large paved areas. Sensors should be housed in a suitable radiation shield.
Standard measurement heights:
1.5 m ± 1.0 m (AASC)
1.25 – 2.0 m (WMO)
2.0 m (EPA)
See Section 13 for a list of references that discuss temperature and relative
humidity sensors.
