Micro Manometer 19A/18A  

Micro-pressure gauges are used to measure inert gases in the overpressure, underpressure and differential pressure domain. These instruments have high measuring sensitivity and resolution (scale length up to 4000mm). With the aid of the mirror ring and knife-edge pointer, measured values can be read accurately and free from parallax error. The micro-pressure gauges can be built into control panels, portable metal boxes or calibrators.
