A large touch screen display is on the upper front of the instrument giving a clear information about the status of the analysis.
All information's are in on screen
Information's are given to guide the user through the instrument setup
Only follow the displayed info and at the end start the titration.
Fill up the coulometric titration cell, start instrument, the instrument check the blank background, titrate by microcoulometry automatically this blank down and check for stable base line.
A soon the value is stable, a message inviting you to inject the sample in the cell is displayed, the titration starts automatically until the end, and finally the result is displayed and registered in the internal memory file.
The previous analysis results can be researched, displayed, recalculated, printed or exported via USB interface.
Of course a balance can be connected with the instrument
The VA-51 oven module is available for desorbtion of water, up to 300°C .
Very simple to use, the sample boat is automatically pushed into the transparent oven, where the melting of the sample can be easily monitored.
At the end of the analysis a simple screwed plug give you access to the sample boat.
Maintenance is easy, directly from the front.
The glass titration cell is completely closed and have at the top side some holes (glass-glass connection) accepting the titration electrode and the detection electrode. One can be equipped either with a glass plug or a gas bubbler if you use the VA-51 Oven option.
On the side of the titration cell, your will find an sample injection port, closed with a silicone septa, so it’s easy to inject liquid samples or, by removing the Teflon plug, pour inside the cell your solid sample.
The concept of this cell give the insurance of no leakages or humidity inrush.
As option, our carriage device is used for on site samples analysis, including a separated battery.
Appreciated in industry and refinery, you can make in process analysis in short time, avoiding any contaminations due to transport of the sample at the lab.
