The HCTEK321 is a ruggedized transit case specifically designed to provide travel and storage protection for TDS3000B, TPS2000, TDS2000, TDS1000 and TDS200 Series oscilloscopes. The case protects instruments from shock, vibration and moisture and provides room for associated accessories, such as probes, adapters and manuals.

Other features include an air pressure equalization control valve for use during air transport and security rings for use with locks (locks not included).

The HCTEK321 consists of a heavy duty outer shell and an inner layer of foam. The oscilloscope is placed in a AC3000 (TDS3000B) or an AC2100 (TPS2000, TDS2000, TDS1000 or TDS200) soft case, and inserted into the foam cavity. The AC3000 or AC2100 soft case is a required component of this system and must be purchased separately.
