The Graham Field 175 series represents a standard in manual blood pressure monitoring. The 175S model features a traditional blue cotton cuff that is comfortable for patients and easy to clean, while the 175GY is part of the Labtron line and utilizes a durable gray nylon cuff. Both units are equipped with a precision 300mmHg no-pin stop manometer and a chrome-plated brass air release valve for controlled deflation. These sphygmomanometers are designed for long-term clinical use and come with a zippered leatherette carrying case for portability and protection between patient rounds.
