EmStat4T 手持式電化學/阻抗分析儀
EmStat4T 是一款具有觸控螢幕的可程式手持式電化學/阻抗分析儀,非常適合感測器研究和基於感測器的應用。它提供兩種主要操作模式:
主要特點


視覺化方法腳本編輯器
建立您的 EmStat4T 應用
強大的 MethodSCRIPT™ 語言讓您可以輕鬆建立自己的應用程序,並在 EmStat4T 上運行。使用我們的視覺化 MethodSCRIPT 編輯器編寫應用程序,該編輯器會自動為您產生 MethodSCRIPT 程式碼。
您的測量資料已安全存儲
內部儲存
EmStat4T 配備 500 MB 內建儲存空間,可儲存您的測量資料。所有內建儲存的測量資料均可使用適用於 Windows 的PSTrace軟體輕鬆瀏覽並傳回 PC。無論您攜帶儀器到哪裡,您的數據始終與您同在。
