Eleven-liter vacuum tank with 12 VDC diaphragm <br /> pump and gauge calibrated in both tank volume and vacuum <br /> pressure. Capable of a vacuum up to 21 in. Hg(70 centibars). <br /> Also includes a sampling valve, a line vacuum gauge,and a <br /> pump control switch. The vacuum tank gauge provides an <br /> accurate measurement of purge volume from the probed <br /> hole and allows regulation of the maximum applied vacuum. <br /> The line vacuum gauge indicates pressure at the probe head ,,; �::,.�•.. .
