This device connects easily to a PC, allowing users to adjust pressure settings, capture pressure values, and manage reference pressure settings directly from the computer. In addition, one controller can detect up to four points at the same time, which improves efficiency and reduces system complexity. Moreover, the system supports mixed connections with sensor heads of different ranges, offering greater flexibility in configuration. Furthermore, it provides separate settings for up to four channels, ensuring precise control and reliable operation across multiple measurement points.
