Vernier height gauges are commonly used in health offices to measure the patients' heights. A vernier height gauge consists of three major parts: the main plate, vernier plate and clamp. The main plate is stationary and is attached to the base. The vernier plate slides up and down the main plate and is locked into place by the clamp. A user can read the measurement by using the marks along both plates.
