summary:
The RGY-501 digital pressure gauge uses high-precision and low-power large-scale integrated circuits as its core components, mainly composed of high-precision measurement chips, battery charging protection circuits, sensors, and signal processing circuits.

This product uses a microprocessor to automatically compensate and correct instrument zero drift, nonlinearity, etc. It also utilizes high-performance devices such as high stability pressure sensors and 24 bit A/D converters to ensure instrument accuracy and reliability. This instrument can set various functional parameters on its own, with flexible applications and various functions to choose from. It can be used as a high-precision pressure calibration standard (meter), as well as a working instrument, for measurement and scientific research in laboratories and fields in industries such as power, metallurgy, petroleum, and chemical.
