* All figure intervals and smallest interval depicted in this chart represent typical artwork layout and may not be accurate for all gauges. Note: All ranges are in Hg and/or psi. If a scale other than Hg or psi is required, convert the pressure range code to the customer-specified units and use that in the product description code when specifying the product. For dual range specify the range code for the first engineering unit (ex. For a dual range with units of KGC/IKPA the range should be specified in KGC). Product Dimensions
