The Ashcroft Model 2008 Pressure Gauge is designed for easy installation in equipment panels. The 2008S provides exceptional quality, durability, and performance. It is an ideal product for many installations and will easily retrofit to existing panels. The PowerFlex movement provides superior resistance to shock, vibration and pulsation, and extends product life while reducing maintenance costs. True Zero reduces reading errors by using a "zero box" instead of conventional dial pins (posts). The PLUS Performance option dampens vibration and shock and pulsation effects, providing liquid-fill performance in a dry gauge.
