The series is durable thanks to the steel and aluminium construction.
The 111.20 series includes analogue steel pressure gauges with increased durability. Their measuring ranges span from 0..0.6bar to 0…600bar. They can operate in ambient temperatures ranging from -40°C to 60°C and media with a maximum temperature of 60°C. The primary applications of the products include the HVAC and gas sectors. One of their strong points is the high ingress protection rating (IP54). They are fitted with M20 connections (located at the bottom) and aluminium faces with diameters of 100mm or 160mm.
