The base threaded nut is carbon steel with a black-oxide and wax finish for corrosion protection (a stainless steel version is also offered)

This helps to reduce internal tensions that are generated due to excessive thermal expansion of the inner ring compared to the outer ring

The psychrometer simultaneously displays key psychrometric data points

for lightning-fast bit changes with only one hand without auxiliary tools of even the smallest bit sizes
