Abstract: A precision detection device for a force standard machine includes a first hydraulic cylinder, a pipeline and a force loading device. A liquid medium is disposed in, the first hydraulic cylinder, and a liquid level area of the liquid medium is a known Value. The pipeline is a hollow tubular structure, and a first end of the pipeline is communicated with the liquid medium in the first hydraulic cylinder. The force loading device acts on the liquid medium, in the first hydraulic cylinder to produce a pressure increment or a pressure intensity increment on the, liquid medium. A force value comparison machine and a precision detection method for a force standard machine are also provided.
