Vacuum Gauge

“Telelin” make Mc-leod gauges measures absolute vacuum in its very last stages. Mc-leod gauge manufactured by us are used by OEMS and various Oil companies for measuring vaccum . Thus our large client base and repetitive orders have made us amongst the leading manufacturer, exporter & supplier of Mc-leod gauge in Mumbai, India .
Model No : MG-6 Portable Mc-leod gauge, with stand & 1st fill Mercury.
The vacustate suitable for measurement of vacuum in the range : 10 mm. to 10-3mm of Hg. (i.e. 10 mm. to 0.001 torr) with stand & 1st Mercury. This gauge avoids use of a movable reservoir of mercury and also requires only about 14 cc. of mercury for first filling. The total size of this gauge is about 9” x 6”. Metallic stand with Rotating arrangement & 1st fill mercury is provided.
WORKING OF THE GAUGES :
The system of which vacuum is to be measured, is connected by flexible rubber tubing to nozzle on the back centre of gauge at A. Gauge is in Horizontal position-1 initially. To take vacuum reading, gauge is to be rotated in the vertical position-2. Mercury runs out of the container B, compressing the residual air or gas. contained within region C & D, to short length of capillary tube C & E. By arranging that the level in the comparison capillary F is opposite the end of the graduated capillary C & E, slight adjustment of gauge above the vertical axis is needed to adjust the mercury level correctly. the Reading in tube C-E is absolute Vacuum in mm of Hg in your line.
