KF-875、KF-UNI and KF-LAB
Karl Fischer 絕緣油微水含量測量儀
- Karl Fischer 滴定原理
- KF875優化了絕緣油的測試并其測量開關及變壓器油的比重為0.875，儀器很輕便
- KF-UNI比KF875測試范圍要廣，樣品數據輸入比KF875要更簡單些，也十分輕便
- KF-LAB測量開關及變壓器油的比重為0.6－1.4
- 適合分析任何Karl Fischer試劑
超過20年的經驗和不斷的改進設計才有今天的Megger KF875，KF-UNI和KF-LAB絕緣油微水含量測量儀。這些儀器的精確度都非常高。
KF875和KF-UNI儀器都非常輕便，并且帶有打印機和運輸盒，使用和移動都很方便，得到的結果精確度也很高。KF-LAB是主要為實驗室使用而時間的，使用主電源供電工作，而且不帶內置電池和運輸盒。
KF875的一鍵式操作非常簡單，不需要特別的知識，也不需要特殊的訓練就可以操作。結果會顯示在儀器的顯示屏上，在內置的打印機上也會有水的微觀圖和結果單位是一毫克每千克（也可以是一克每百萬 即 ppm）
KF-UNI允許樣本滴定的重力范圍在0.6到1.4之間，也允許樣本的尺寸不同。如果不需要打印也可以不用打印出來，打印出來的結果的單位是ppm，mg/kg，%和毫克。是根據樣本的重量，樣本的體積，樣本的重力來計算出來的。
KF-LAB分析儀樣本滴定的重力范圍在0.6到1.4之間，他同時也能設置他的重力為化重力0.875。這就意味著在測試變壓器絕緣油時候設置很簡單，但是能用來測量的油的范圍卻很廣泛。
- KF875和KF-UNI都很輕便是為室外使用特別設計的，這兩個儀器都帶有一個標準打印機，內置電池和運輸盒。通過主電源供電或者內置可充電電池供電或者12V變壓器供電使儀器的可攜帶性更強。
- 每個儀器都使用ACE控制系統消除錯誤，許多Karl Fischer試劑由于電解的影響，使其油內的水含量變高，這就需要我們頻繁的檢測油的含量。KF875，KF-UNI和KF-LAB都集成了ACE（自動補償錯誤）控制系統。
- 每種儀器都應用了Karl Fischer 滴定原理。是絕緣油微水含量測量的標準測試原理（ASTM
D1533, BS EN 60814:1998,IEC 60814:1997） - KF875和KF-UNI里面都帶有可充電電池，能夠精確的測試才獲得的新鮮的油樣本，消除了由于時間的原因使油變壞的可能性。
- KF875和KF-UNI可以由內置可充電電池或者主電源供電，使用這些儀器既可以在實驗室使用，又可以在工地上使用。
KF875 and KFLAB
Karl Fischer Moisture In Oil Test Sets
- Coulometric Karl Fischer titrimetry
- KF875 optimized for insulating oil with an SG of 0.875, completely portable
- KF-LAB MkII offers greater flexibility, versatility and sample data input than
the KF875; also completely portable - KF-LAB MkII analyzes materials with an SG between 0.6 & 1.4, plus insulating oils with an SG of 0.875
Over 20 years experience has led to the development of the Megger KF875 and KF-LAB MkII Coulometric Karl Fischer Test Sets designed to determine moisture in oil, to provide highly accurate results on-site. The KF875 and KF-LAB MkII are highly portable instruments, complete with integral printer and carrying case, are easy to use and provide highly accurate results.
Optimized for testing insulating oils with a specific gravity of 0.875, the Megger KF875 simply requires the operator to press one button and inject a 1ml sample into the test cell. The simple ‘one touch’ operation makes the KF875 so easy to use that it requires no specialist knowledge or training to use it effectively. Results are presented on the instrument display and on the integral printer in both micrograms of water and in milligrams per kilogram (parts per million, ppm).
The KF-LAB MkII allows the titration of samples with a range of specific gravities from 0.60 to 1.40 and also permits the use of different sample sizes. The KF-LAB MkII also has a default setting optimized for analyzing insulating oils with an SG of 0.875. This means it can be used to measure water content in a variety of different materials but is also easy to set up for transformer insulating oils.
