Accurate to within ±3%, the McLeod gauge is the most convenient and economical instrument for measuring low pressures from one micron up
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 [ST] 20/65.
The McLeod gauge is offered in four ranges, so that it is possible to accurately measure any pressures between one micron and 15mm.
Ordering information: Available as a complete item, including glass body, stand with joint, and scale, or these items may be purchased individually. Optional: Mounting rod that threads to back of stand for rack mount. Rod is 1/2" O.D. x 6" long. Requires 20mL of mercury, which is not supplied.
