Digital Electric Contact Pressure Gauge
Product Overview
Section titled “Product Overview”The Digital Electric Contact Pressure Gauge is a digital pressure gauge developed to replace mechanical electric contact pressure gauges. It uses pressure sensor technology and has no mechanical contact structure, giving it good vibration resistance and durability.
The gauge provides one-key zero reset, three display units, stable circuit design, anti-electromagnetic interference, surge protection and reverse polarity protection. The 304 stainless steel housing and fittings make it suitable for demanding industrial applications.
