Fully automatic Coulomb method moisture analyzer

Product Introduction

1、 Product Introduction

Fully automatic Coulomb method moisture analyzerThe 917 Coulometer is a fully automatic Karl Fischer coulometric moisture analyzer launched by Swiss company Wanton for daily analysis. This instrument has two modes: Karl Fischer coulometric moisture measurement and bromine valence bromine index measurement.

IIFully automatic Coulomb method moisture analyzerProduct Features

1. The instrument has high integration and a simple and stylish appearance design;

2. It has two functions: Coulomb method for moisture determination and bromine valence bromine index determination;

3. Built in suction and drainage device can ensure safer use for users;

4. Can automatically detect whether the sample has been added, and can start automatic titration after the sample is added;

5. The experimental report is stored on a USB flash drive for anti-counterfeiting purposes, generating a PDF file that can be sent over the network;

6. It can support multiple conversational languages, including Chinese.

7. Flexible upgrade, compatible with 860 and 885 Karl Fischer sample heating processors. But one thing to note is that,Not all samples can be directly injected, and it is recommended to use it in conjunction with a Karl Fischer furnace when the following conditions exist.

(1) The sample cannot be completely dissolved (plastic particles, polyester chips, artificial bones, etc.);

(2) Side reactions occur between the sample and Karl Fischer reagent (lubricant additives, samples containing aldehydes and ketones, etc.);

(3) Slow release of sample moisture;

(4) The moisture in the sample can only be released at high temperatures;

(5) The sample will contaminate the titration cell (lubricating grease, etc.);

After being used in conjunction with a Karl Fischer oven, the moisture in the sample is heated and separated, transported to a titration cell via a dry carrier gas, and then measured for moisture in the titration cell.
