| 1 Stated analytical performance is achievable under controlled laboratory conditions that minimize operator and standards errors. 2 Total measurement accuracy includes separate contributions from both the standards accuracy and the Instrument Accurac 3 Conductivity and accuracy specifications are met as shown above for ambient temperatures from 10–40 °C (50–104 °F). When calibrated at 40 °C, the following specifications are met at 40–55 °C (104–131 °F): conductivity accuracy is } 2.4%, and TOC accuracy is } 6.7% on 500 ppb C of sucrose. 4 Sample water quality with a conductivity >1.4 μS/cm may result in reduced TOC accuracy. |
CheckPoint 總有機碳 (TOC) 感測器有兩種型號：CheckPoint Pharma 和 CheckPointe。
這兩種型號的感測器都帶有一個乙太網埠 (通過 TCP/IP 和 Modbus) 和一個 USB 埠，方便資料下載。CheckPoint 總有機碳 (TOC) 感測器無需使用試劑，易於操作和維護。感測器的校準穩定期通常為 6 個月。兩種感測器都允許用戶在 15 秒到 8 小時的範圍內調整資料輸出間隔。兩種感測器都非常容易操作，維護要求很低，提供方便的電池供電選項，採用直接電導 (DC) TOC 測量技術，比同類 DC 技術設備能夠測量更多的有機化合物。
