Additel的273Ex是一款本質安全的手持式多功能壓力校準器，具有彩色觸摸屏、類似智能手機的界面、內置快速測試任務和可選HART通信功能。這種創新的Additel產品極大地改進了防爆現場測試和校準。Additel 273Ex具有內置的大氣壓力傳感器，因此可以方便地實現絕對壓力和表壓。通過三個壓力模塊輸入，一個在底部可切換，兩個在側面可切換，用戶可以相應地配置設置，并輕松滿足幾乎任何環境中的壓力校準和測試需求。
本質安全
ADT273Ex已通過權威機構最嚴格的ATEX、IECEX本質安全認證。防爆等級為Ex ia IIC T4 Ga。可廣泛應用于潛在爆炸性氣體環境，如石油和天然氣平臺、煉油廠、化工和石化廠、制藥行業、能源和天然氣加工行業。每個本質安全校準器都有一個先進的透反彩色LCD顯示屏，在陽光直射下觀看時可增強可視性。無論你的工作帶你去哪里，這些校準器都能勝任任務。
現代用戶體驗：
Additel在使用這款革命性的新型校準器時，為我們的客戶提供了盡可能好的體驗。與市場上的其他校準器相比，彩色觸摸屏顯示器提供了令人耳目一新的直觀體驗。憑借易于導航的菜單結構和快速的觸摸屏響應，您會發現ADT273Ex校準器使用起來簡單而強大。這種易于閱讀的顯示器不僅使用起來很有趣，而且堅固耐用，可以滿足現場或實驗室繁忙技術人員的需求。
可選HART通信：
ADT273Ex手持式壓力校準器支持HART通信協議，為寬壓力范圍內的變送器提供壓力校準解決方案。ADT273是一款高度便攜的設備，可以使用現場可切換的壓力傳感器精確測量壓力，并讀取傳感器產生的電流或mV。它甚至可以在校準期間向功率傳感器或變送器提供激勵電壓（回路電源）。
