產品說明：

SMR4000-x 是一套經過嚴格控管的多頻道強震紀錄系統。它的優點具備低耗電量、高執行力，可用於廣泛用途以及擁有24-bit 高解析度模組。模組的設計根據頻道可增加4至12個頻道，多頻道 (8 至12頻道) 適合運用在大型建築物的監測。不同感應器可以在喧雜的建築物環境執行並傳入資料，多數感應器傳輸資料非常容易，而且資料的傳輸經由 Euro Block 模式連線，透過環境將電纜密封固定。

連續資料在發生同時紀錄的時候，能夠被分割為虛擬資料，而且應用於不同事件的濾波器會配合不同的觸發通帶濾波與採樣率。

擁有專利的 Smart Time 系統受 DSP 控制，維持極度準確的時間控制以及配合偶發呼叫至GPS接收器。資料採樣準確地與內部時間同步，以致於所有頻道在所有的時間範圍內擁有準確的採樣數，而且資料不需要再度索引。

例如個人電腦、硬碟和 GPS 的動力挨餓部分對週期極為低的責任起作用。然而， 強大個人電腦的存在對用戶開各式各樣的選擇。工業標準個人電腦 / 104 允許把許多外圍設備用於模組、stackable 版式，如同以太網卡片、無線局部區域網路卡片、衛星通信硬體等等。

產品說明：

DAS-6502 是一套經過嚴格控管，具有高執行力及 24-bit 高解析度的海底地震紀錄器。這套系統是專門為海底地震研究所研發設計。 這種地震紀錄器的特色是利用 4 至 8 個具有高解析度的通道對通道類比─數位轉換器確保各頻道之間的數據不會歪斜、錯誤；以及一個耗費電力極低，且具有高執行力的數位訊號處理器。他們控制資料的取得，並及時將資料數位化、過濾。

此系統能夠安裝在海底生物或鈦金屬存在的地方，命令其準備部署在海底生物系統。為了能夠讓以上裝置不斷連線，6503 Sensor 是最好的感應器選擇。DAS-6502 海底地震紀錄器能夠在電腦PC的桌面直接執行，非常便利。紀錄器的時間裝置，預先調整為隨著 GPS 而隨時更新。水晶振盪器的精確校準大約需要兩天時間讓系統正常運轉，以便安裝時更適應海洋底部的溫度。準確的即時時間校正系統能夠在 ±0.016 ppm 之內校正振盪器頻率。一旦進入水面之下，溫度控制的水晶振盪器能夠保持極為穩定的狀態，讓實驗的進行保持精準的計時。

SRAM 緩衝器減少電腦PC與硬碟之間的壓力，減少作業時發生不必要的噪音。典型的週期功率能夠讓電腦 PC 及硬碟在2分鐘之內運轉，每5至8個小時提供三個頻道 @ 100sps 16MB 的緩衝區空間。大容量且可拆卸的硬碟提供資料儲存的便利性。

產品說明：

EP300-OBS 為多頻率且低噪音的海底地震儀感應器，力平衡反射的提升使感應器的動態範圍擴展，以及良好的穩定性及線性越過整個通帶都是 EP300-OBS 的特色。此項裝置使用三個電能轉換器沿著 N、E、Z 三個軸向，利用直角安裝。這些轉換器比傳統電子機械傳感器更具優勢，尤其是他們擁有更寬廣的地表電壓轉變率，基本上從幾赫茲到最長的週期，造成獨特的干擾曲線。

如同其他地震儀，EP300-OBS 的控管極為嚴格，而且其設計專為 OBS 所使用。EP300-OBS 不需要 Mass Centering 或 Mass Locks，也不需要特別的安裝設備或步驟。它耗費的電量極低，能夠在多種溫度範圍下，以及多種安裝傾斜幅度下操作。其所有權的成本耗費極低，而且儀器本身完全不需要保養，儀器的壽命大約3至5年。
