Description: Product Name: Hydraulic Pressure Gauge Material: Stainless steel + brass Connection: Brass 1/4 NPT Male 55mm (22") Face Accuracy: 2.5; 1.6 Environmental conditions: -40 ~ 70 Degree, relative humidity less than 90%. temperature: not more than 0.4% / 10 Degree (temperature deviation from 20 ± 5 Degree) Features: 1. Great for measuring any fluid, liquid or gas that is compatible with brass. 2. Seismic pressure gauge is mainly used in metallurgy, electric power, petroleum, chemical industry, light industry, machinery and other industrial sectors detection. 3. Instrument can measure gas and the average of liquid pressure pulsations. 4. To overcome the media strong pulse and environmental vibration to instrument damage, ensure the accuracy of the reading. Structural principle: This instrument consists of pressure systems (including joints, spring tube, etc.), the transmission mechanism, indicating devices and enclosure components. Package included: 1X Hydraulic Liquid Filled Pressure Gauge 0-5700 PSI Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-YJL official store
