After the smart scale enters the physical examination site, it has a great impact and improvement on the traditional method of measuring height and weight. Compared with the original manual height measurement and scale reading measurement method, the intelligent height and weight scale have obvious advantages in the acquisition method of height data. It does not require the operator to measure the manual pressure bar and does not need to scale again. ruler reading. The non-contact ultrasonic measurement method effectively guarantees the stability of the height measurement data and the fast and orderly physical examination in large-scale physical examination activities.

    The weighing performance of traditional mechanical scale products mainly depends on the quality of the internal spring components of the product. A good spring body can be used for at least two years, while a spring body with poor quality will often appear irreparable within 3 months. Damage is also an unavoidable loss and maintenance problem when choosing a mechanical height and weight scale. The intelligent height and weight scale adopts a high-precision ultrasonic sensor and precision balance pressure sensor and has the function of automatic compensation of ambient temperature and automatic compensation of regional acceleration. From the perspective of long-term use, the service life of the intelligent height and weight scale is at least 10 years, far exceeding the old mechanical scale.

     In addition, the intelligent height and weight scale also have an intelligent digital display, with a voice broadcast system, to help many illiterate people know their health data, the screen displays many human health components including height, weight, BMI index, and a number of physical examination data. As a reminder, these are all things that traditional old-fashioned mechanical scales can't provide. But the inconvenience of this scale is that it can only satisfy certain people and it is expensive.
