Mercury Temperature Gauges

Mercury Gas Filled Temperature Gauges are economical rugged reliable and accurate measuring instruments are made of bulb transmitting capillary and flat bourdon or coiled bourdon tube which are pressure filled with Mercury/Inert Gas. The system is pressurized with mercury/Inert Gas. Variation of the ambient temperature are compensated by means of a Bi-metal link between movement mechanism & Bourdon Tube.Construction Features td p { margin-bottom: 0cm; }p { margin-bottom: 0.21cm; } Dial Size 100mm & 150mm.
