SPR-524 is an Ultra-miniature Pressure Catheter (2.3F Nylon) with a single 3.5F pressure sensor  mounted on the side of the tip. It is suitable for use in rabbits, dogs, pigs or sheep.

The catheter has a straight tip and a body which is narrower than the tip, conferring flexibility and minimizing obstruction of vessels or valves. The effective length at 2.2 F is 100 cm. The SPR-524 features advanced sensor design for maximum durability and a drift less than 3 mmHg/24 h; therefore, it is reusable but cannot be repaired.

The catheter uses a low-profile connector and therefore requires a TC-10D catheter interface cable for connection to the bridge amplifier from emka TECHNOLOGIES.
