Product Details:
This water / dust proof and contaminant proof keyboard with tactile
feedback keys and sealed surface is ideal for industrial, marine, and
medical use, as well as other applications where moisture, cleaning,
and durability are a consideration.
Because it is also quieter than "standard" professional keyboards, they are great
for applications where noise generated from key-clicks is a problem.
It is compatible with standard keyboard layouts and drivers are not
needed. USB and PS2 compatible. 85 key layout, no number pad.
