It carries multiple approvals, including ATEX, IECEx, FM, and CSA. A flush-diaphragm version is available for crystalline or viscous media and for applications that require residue-free cleaning.<\/p>\n<p><strong>Large selection of approvals<\/strong><br \/>\nThe IS-3 is available with a broad range of internationally recognised hazardous-area approvals, including options for smaller regional markets. For system suppliers, approval combinations help reduce the number of instrument variants that must be stocked for different markets.<\/p>\n<\/div>\n<div class=\"column is-half\">\n<p><strong>Wide range of configurations<\/strong><br \/>\nThe IS-3 offers extensive customisation and flexible system integration. The high-pressure version supports up to 6,000 bar [87,000 psi]. Depending on the configuration, it is available with ingress protection up to IP68 and for process media temperatures up to +200 \u00b0C [392 \u00b0F].<\/p>\n<p><strong>Proven quality and reliability<\/strong><br \/>\nThe IS-3 and its predecessors have provided reliable service for more than 20 years.
