專用於需要小型標準鉑電阻溫度計的計量工作

• 溫度從– 260 °C (13 K) 到232 °C
• 在100 °C 範圍內的典型穩定性為0.001 °C
• 小尺寸套管封裝消除了套管漏熱效應

有時您需要用標準鉑電阻溫度計進行測量，但對特定的應用場合而言，傳統的標準鉑電阻溫度計太長，或者使用起來不方便。

如今，Fluke Calibration 製造出了一款小巧的玻璃套管標準鉑電阻溫度計，非常適合用於低溫實驗、熱量測定以及其他需要小型標準鉑電阻溫度計的計量工作。

5686 是真正的標準鉑電阻溫度計。將高純度鉑絲人工纏繞在採用無應力設計的玻璃十字骨架上。

玻璃套管與鉑絲的熱膨脹相配，以便在所有操作溫度下均確保實現真正的密封。小玻璃套管採用壓力密封，隨機帶有木質攜帶箱以起到保護作用。

Designed for metrology work requiring small SPRTs

• Temperatures from –260 °C (13 K) to 232 °C
• Stability typically 0.001 °C over 100 °C range
• Miniature capsule package eliminates stem conduction

Sometimes you would like to make SPRT measurements but traditional SPRTs are too long or awkward for a particular application.

Now Fluke Calibration makes a miniature glass capsule SPRT, which is perfect for cryogenics, calorimetry, and other metrology work requiring small SPRTs.

The 5686 is a true SPRT. The high-purity platinum wire is hand-wound on a glass cross frame in a strain-free design.

The glass capsule is designed to match the thermal expansion of the platinum wire to ensure a true seal at all operating temperatures.

The capsules are pressure sealed and come protected in their own maple case.
