精準穩定的超低溫計量爐

福祿克計量校準部的9190A超低溫計量爐是精準穩定的超低溫計量爐。對於嚴格的質量控制和符合規程的過程控制，它是一個理想的儀器。上述這些應用包括熱電阻，熱電偶，測溫儀和傳感器的現場和實驗室的驗證和校準，而這些溫度傳感器和溫度表廣泛應用於很多低溫過程控制設備，例如醫用冷凍箱、實驗室冷凍箱、冷庫、血庫、高壓滅菌器和凍乾機等。

清潔的環境

恆溫槽是穩定和均勻的溫度源，但是它們並不十分清潔乾淨，不適合對清潔要求較高的實驗室應用。恆溫槽的體積較大，從而限制了它們的便攜性。恆溫槽使用的液體容易濺出，並產生油煙，從而污染了實驗室環境。9190A超低溫計量爐正好可以補全恆溫槽的這些不足之處。它的寬溫度量程正好可以覆蓋醫藥，生物和食品等行業的溫度範圍。9190A緊湊輕便，易於攜帶。由於不使用液體，所以可以在各種需要清潔的環境下使用。由於9190A的控溫速度比恆溫槽快，所以它可以提高校準工作的效率。

Ultra-cool dry-block calibrator with best-in-class stability

The Fluke Calibration 9190A Ultra-Cool Field Metrology Well is the most accurate and stable,

cold temperature dry-block on the market. It’s ideal for applications that demand strict quality control and regulatory process compliance.

These applications include on-location validation and calibration of RTDs, thermocouples,

thermometers, and sensors used with process control equipment such as medical freezers, laboratory refrigerators, cold rooms, blood banks, sterilizers (autoclaves), and freeze dryers.
