A10, A15, A20 Nagano KeiKi - Đồng hồ đo áp suất Nagano Keiki 
The bourdon tube pressure gauge is offered and made in accordance with JIS B 7505-1. The gauge is easy to handle with its structured simplicity with elastic measuring element (bourdon tube) into a deflection caused by applied pressure change transmitted to a rotary geared movement carrying pointer. It is applicable to variety of applications offering wide varieties of pressure ranges.

　 For constant pressure
The maximum operating pressure should not exceed three-quarters of the full-scale range. For fluctuating pressure
The maximum operating pressure should not exceed two-thirds of the full-scale range.
Select proper wetted parts compatible with process fluid (gas and liquid) which the gauge will be subjected.
　Please refer to JIS B 7505-1 for details.
