brief introduction
The YK-21 desktop digital pressure gauge is separated from the pressure module, making it easy to operate. One digital gauge can be configured with any number of intelligent modules from negative pressure to positive pressure. It is mainly used to calibrate pressure (differential pressure) transmitters, precision pressure gauges, ordinary pressure gauges, blood pressure monitors and other pressure instruments, as well as precision pressure measurement.
