YL-819Z digital electric contact pressure gauge

YL-819Z is a digital electrical contact pressure gauge with a 75mm axially installed stainless steel casing (made of 304 stainless steel), used as a replacement for mechanical electrical contact pressure gauges. This electric contact pressure gauge is mainly designed to replace traditional mechanical electric contact pressure gauges, and is particularly suitable for use in working conditions with frequent pressure shocks and strong on-site vibrations. It has the characteristics of anti vibration, long service life, simple operation, and clear display. At the same time, this digital electric contact pressure gauge has the function of switching multiple pressure units and resetting with one click.
