Accurate to within ±3%
For the complete options: type B has the lowest reading at .005, type C at .010, and type D at .050.
The McLeod gauge is the most convenient and economical instrument for measuring low pressures from one micron up. The ACE McLeod gauge is offered in four ranges, so that it is possible to accurately measure any pressures between one micron and the highest reading on our D size, which is 15 mm. All gauges are fabricated from calibrated ACE Trubore glass tubing, to assure uniform and reproducible readings between gauges. This feature is also important when broken scales must be replaced, since it enables us to supply new scales without recalibrating the instrument. The McLeod gauge is useful for measuring pressures of true gases only. Water vapors and other condensable vapors should not be permitted to enter the gauge, since they can cause erroneous readings. Metal locking device has positive holding action — eliminates need for glass hooks and springs. Gauge will hold at any operating position to which it is rotated. Joint is standard taper 20/65. Optional: Mounting rod that threads to back of stand for rack mount is 1/2" O.D. x 9" long.
Ordering information: Requires approximately 20 mL of mercury, which is not supplied.
