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 容量法微量水测定仪

符合GB6283-1986《化工产品水分含量的测定   卡尔·费休法》（通用方法）GB/T606-2003《化学试剂，水分测定通用方法   卡尔·费休法》等方法标准要求。

采用容量法卡氏试剂，在一个以碘单质浓度为标准的平衡体系中，样品中的水分使碘单质浓度降低，从而破坏这平衡体系，加入容量法卡氏试剂后使其重新平衡，这一过程中消耗的容量法卡氏试剂的体积通过准确计量，自动计算出样品中的含水绝对质量及其浓度。

技术指标：

★ 水分含量浓度测量范围： 10ppm～100% H2O

★ 绝对含水测量范围： 50μg～200mg

★ 测量电极电压测量范围：　电位（mV）：0～1000

★ 分辨率：电位（mV）：0.015

★ 一般测定时间：40秒～数分钟(依样品进样量、试剂滴定度及水分含量而定)

★ 误差范围：10%（小于500μg），5%（不小于500μg）

仪器特点：

²        平衡点判断准确可靠

高性能的平衡点测量电路，可以准确判断至最小10微克水的变化。
