使用環境溫度：-25℃～70℃
使用工作頻率不大于25Hz,振幅不大于1mm。
訂貨時請注明名稱、型號、測量范圍及工作溫度。如有特殊要求，請明確參數，本廠可設計定制特種耐震壓力表。

If the ambient temperature is so high that the gauge pointer does not return zero,in order to resolve it you may stick a small hole on the gauge seal with a needle,and the gauge inner will connect with the atmosphere.
Working condition temperature:-25℃～70℃

Working frequency is not to up 25Hz and amplitude of oscillation is not to up 1mm.
Please note name,model and measuring high limit on your order,and special filled pressure gauge can be provide on request.
