The ACD-2H standard digital pressure gauge adopts advanced micro power consumption, high-precision devices, and complete embedded software technology. The instrument adopts temperature dynamic compensation technology, which can ensure that the instrument accuracy level can be met in the full temperature range. It is equipped with high-performance industrial lithium batteries and can work continuously for 10 years under normal conditions. The standard signal is fully isolated RS485 communication interface. When there is external power, it can directly communicate with the computer through communication software. The communication software has processing functions such as data acquisition, curve, storage, and reporting.
