Q&A: AT-710 Burette piston won't move

By Hank Levi on Tue, Jun 19, 2018 @ 03:36 PM

Sometimes pressing a button and hearing a beep just drives you crazy.  We know.  Below we received some video of a problem where the operator could not move the piston burette up or down on their automatic titrator.  We decided to replicate the problem and then show how to take corrective action.  We hope you find the video informative even though it is raw footage.  Send us your questions too.  Video, audio, pictures, etc.  We can use any format.

Sneak Peak at new Potentiometric Titrator AT-700!

Potentiometric Titrator AT-700
















 

 

 

 

 

Here it is!  The new AT-700 Potentiometric Titrator with integrated sample changer, CHA-700, is coming out soon.  Manufactured by Kyoto Electronics Manufacturing (KEM) this will mark their 7th generation of industrial grade, high quality, titration instrumentation.  We have not yet received all of the details on this amazing looking, newly designed potentiometric titrator but can tell you that it incorporates a carousel design sample changer that handles eight samples.  From the photo you can see how the sample changer's compact design revolves around the Potentiometric Titrator.  There are a few key design features on the new potentiometric titrator:

  • No need to read measurement parameters
  • New burette system
  • All-in-one compact design

We're told this new design will make significant improvements with the measurement of Mercaptans down to 1PPM (ASTMD3227,UOP163,IP272).

*Advantages include a special sealing cell and electrodes to avoid oxidization of mercaptan sulfer under atmospheric conditions.

*Application: Determination of mercaptan sulfer and hydrogen sulfide in fuels and liquid petroleum gases (LPG) is one of the important applications in petroleum and gas analysis.

We anticipate this newly designed Potentiometric Titrator will serve many other titration applications and provide operators with a compact yet fully automated functioning titrator.

As we receive more information on this new titration system we will let you know.
