The apparatus consists of a panel for wall mounting on which are fitted -1.0 to 20 kg/cm2 x 0.1 kg/cm2 a pressure gauge, Bourdon tube type 20 cm dia. Manometer: Glass U-tube manometer for measuring low positive pore pressures negative pore pressures and checking zero error of pressure gauge. It is provided with a mercury trap (Mercury supplied at extra cost). Null indicator made out of clear transparent perspex with mercury trap and cursor to indicate the mercury level. Burette : 50 ml Burette for measuring the volume change in the soil specimen. Pressure pump fitted with four sleeve packed valves. Operated by mean of a hand wheel on the end of the piston rod which is threaded through the pump cap and gives a smooth, fine adjustment of pressure. Copper coil and water reservoir. The unit is tested against leaks upto 10 kg/cm.sq.
