Execution: Hydraulic measuring stand with central clamping. One hand can remain free for setting up the dial gauge. All joints are rigidly clamped by the central knob. Patented mechanics generate high pressure, allowing the handwheel to be tightened with minimal force. Oil hydraulics are secured against oil loss with double seals. Clamping force can be adjusted continuously. The articulated arms can rotate 360° at the dial gauge holder and swivel over 180°. Dial gauge holder for gauges with a shaft diameter of 8 mm or prism. Magnetic base with a prismatic sole. Strong permanent magnet. Rotary switch to turn the magnetic force on and off. The magnetic force acts through the flat back and the prismatic underside of the base. Note: Hydraulic measuring stands can withstand high temperature fluctuations when the clamp is open. The oil requires some time to adjust to the temperature. In the clamped state, a maximum temperature difference of 15 °C can be achieved without significant pressure fluctuations. These can cause damage to the stand or the objects being held. Delivery includes: Magnetic base No. 440868 Size 1.
