Dual Purpose Pump Physical Education Toys Vacuum Pump Physics Instrument Manual Inflation Pressure Cylinder

SpecificationColor: as Shown in the PictureQuantity: 1Name: dual-use pumpMaterial: Metal + PlasticWeight: 313gPackage Included:2 ×Labs Dual Purpose PumpInstructions for useConnect the instrument to be pumped or hose pumped to the hose connector of the cylinder's intake or exhaust valve. The connection must be firm to prevent leakage or slipping during use. After connecting the hose, the piston can be pushed back and forth for pumping or pumping.Note:1.Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.2.The measurement allowed error is +/- 1-3cm.

• *This pump is a double-acting pumping and pumping bidirectional reciprocating pump.
• *The pumping pressure reaches 6.7*10 to the power of 3Pa, and the pumping pressure reaches 2.9*10 to the power of 3Pa.
• *The reciprocating pumping of the piston in the cylinder produces two functions of pumping and pressing, which can be pumped and pressed continuously by reciprocating through the valve.
• *It's good physical teaching tools, easy to undestand and handle. Great experiment toy.
