This rugged case offers crushproof, water resistant, and dust proof protection to a Model 2401-Series instrument. The single, easy-open latch and stainless steel hardware ensure easy accessibility and durability. The Automatic Pressure Equalization Valve serves to balance interior and exterior pressure to keep water out, as does the O-ring seal and rubber liner. The hard, durable shell and foam insert offer excellent protection whether instruments are transported via common carriers, shipped, transported by users, or stored.
