KF-1 volumetric method for the determination of trace water

Conform to the GB6283-1986 "chemical products water content of the determination of Carle Fisher method" (general method) GB/T606-2003 "chemical reagent, water content determination general method Carle Fei Hugh method" and other methods standard requirements.

The volumetric method reagent, in a iodine concentration equilibrium system of standard, the water in a sample of the iodine concentration decreased, thereby undermining the balance system, added reagent volumetric method after the re balance and consumed in the process of volumetric method for the card's trial agent volume through the accurate measurement, automatically calculate the sample in the absolute water quality and concentration.

Technical index:

This water content concentration measurement range: 10ppm ~ 100% H2O

* absolute water measuring range: 50 g to 200mg

By measuring electrode voltage measurement range: potential (mV): 0 ~ 1000

* resolution: potential (mV): 0.015

* general measurement time: 40 seconds to a few minutes (same goods volume of sample and reagent and water content determination)

Range: 10%. Error (less than 500 g), 5% (not less than 500 g)

Instrument characteristics:

L balance accurate judgment

High performance of the balance point measurement circuit, can accurately determine the minimum 10 micrograms of water change.

L can be manual or automatic measurement of drift, blank

Two ways to make use of the instrument or has been familiar with the operator of the instrument can be handy, accurate determination of the drift to ensure that the blank deduction.

- Determination of solid and liquid and gas samples.

External solid sampling device, can be analyzed easily react with the reagent sample.

L avoid direct contact with toxic reagents

Good sealing instrument. Operators only need to operate the keyboard, automatic replacement of solvents or eliminate waste liquid.

- convenient and flexible operation

Titration speed can be adjusted manually

The titration parameters can be modified to ensure the correct operation according to the different level of the user. The titration process can be modified at any time.

L the man-machine dialogue, large screen display

Full menu parameter operation, showing the titration curve, intuitive operation

L external balance, printer, computer

- titration speed can be adjusted

- 100 groups of data storage

- ten analysis methods, set free

KF-1 容量法微量水測定儀

符合GB6283-1986《化工產品水分含量的測定   卡爾·費休法》（通用方法）GB/T606-2003《化學試劑，水分測定通用方法   卡爾·費休法》等方法標準要求。

采用容量法卡氏試劑，在一個以碘單質濃度為標準的平衡體系中，樣品中的水分使碘單質濃度降低，從而破壞這平衡體系，加入容量法卡氏試劑后使其重新平衡，這一過程中消耗的容量法卡氏試劑的體積通過準確計量，自動計算出樣品中的含水絕對質量及其濃度。

技術指標：

★ 水分含量濃度測量范圍： 10ppm～100% H2O

★ 絕對含水測量范圍： 50μg～200mg

★ 測量電極電壓測量范圍：　電位（mV）：0～1000

★ 分辨率：電位（mV）：0.015

★ 一般測定時間：40秒～數分鐘(依樣品進樣量、試劑滴定度及水分含量而定)

★ 誤差范圍：10%（小于500μg），5%（不小于500μg）

儀器特點：

²        平衡點判斷準確可靠

高性能的平衡點測量電路，可以準確判斷至最小10微克水的變化。
