describe

The precision digital pressure gauge adopts the design concept of analog pressure gauge, but its accuracy is no less than that of digital calibrator. The precision digital pressure gauge combines the high precision of digital measurement technology with the simplicity of analog instrument, its performance, ease of use and instrument function are far from the same competitive products in the supermarket. The accuracy can reach 0.1% of the range (the optional accuracy is 0.05% of the star range), the temperature compensation range is-10- + 50℃, supports 21 standard measurement units, and can be customized measurement units according to customer requirements to avoid complex unit conversion. Sampling frequency: the user can customize the measurement frequency according to the specific application requirements. The star measurement frequency of the standard application is usually 3 times per second, up to 50 times per second, which users should set according to different tests. The pressure gauge also has an energy saving function and can automatically switch to "sleep" mode. In this mode, the battery life can be extended up to 2,500 hours. The pressure gauge uses a new menu navigation and is very simple to navigate. Clear display screen, internal bar chart display interface, and large text display area allow customers to effectively analyze multiple measurement points. In addition, it also has the MI N/MAX (minimum / maximum) function, which not only enables customers to immediately read the highest and minimum pressure, but also automatically stores the maximum and minimum pressure values.
