Also known as "Industrial Process" pressure gauges, this style of gauge is made from higher quality components and thus has accuracies within the ½% full span range. Most are provided "dry" although they can be provided with glycerin or silicon fill.
The movement is more sophisticated than smaller and less expensive gauges having less accuracy and can include features such as an adjustable pointer, safety glass lens, min/max pointers and solid front thus in the event of a catastrophic internal failure fluid would be directed away from the user. These gauges are assembled and tested here in the USA, typically shipping from stock or within a few days after receipt of an order.
