The industrial and mechanical world sees an engineering marvel in the form of H-Heavy duty pressure gauges series. This gauge series has been designed for its precise application in the fields of instrumentation, industrial, and process applications. It proffers accuracy, durability and is effortless to maintain even under difficult and critical situations. Some of the prominent specifications for this H series pressure gauges are – Case sizes 40, 63, 100, 160mm that is appropriate for vacuum to pressure up to 1000bar (15,000psi); Case protection: IP 65 (IP 54 for 160mm (6) case with range 30psi ; Safety category of (EN 837-1); S1 for pressure gauges with blow-out device 100mm and 63mm cases; Vacuum: 30 Hg Vac. to 0 psi and Compound: 30 Hg Vac. Its fabrication of stainless steel case; use of adjustable pointer, and bayonet ring for easy adjustment. The frontal glass is laminated for sake of safety.
