Watertight Instrument Cases

Have a look at our lineup of rugged, watertight instrument cases — large and small — for protecting your delicate instruments. Circuit Specialists' instrument cases come in black and OSHA yellow for easy identification, e.g., on luggage carousels. These watertight cases include high-density foam that is easily formed, providing a snug fit for your cargo. Our top-of-the-line cases even have automatic pressure purge valves to compensate for altitude and temperature changes.
