Matheson offers a wide variety of gauges suitable for most laboratory and pilot plant operations. All of the gauges offered by Matheson are constructed with the 1/4" MNPT inlet located on the bottom of the gauge and are cleaned for oxygen service. Matheson has adopted a dual unit measurement system for the majority of the gauges supplied. These gauges indicate psig or inches of water column and kPa units of measure. All accuracies are stated as a percentage of the full scale reading of the gauge. The gauges are accurate to ±1.6% of the full scale value.  These Very Low Pressure gauges have a front zero adjustment
