WhesseIII, can you help us understand a few of the specifics of your titration by answering these questions?  Send the printout copies to info@scientificgear.com.  thanks.

A: sample name, sample size, not only the oil more detail,,,
B: the method parameter print out copy,
C: result print out copy with the graph and the data list,
D: reagent info., concentration and the name,

Just checked it out and it seems to work fine.  Sometimes depending on your download speed it can take 45 seconds or more to begin playing...if you just click on the play button. Alternatively you can download the podcast video and play it.

Well your right.  The AT210 and CHG-310 were great instruments and many people still talk about how they have tested time and kept on working.  Today if your looking at staying with the KEM titrators there are two options- the 500 series and the 600 series.  Personally I think the 500 series is the next generation workhorse that has been tested and proven in tough environments.  The AT-510 is the top of the line of the 500series and has the ability to use software (ATWin) so you can actually run the titrator from your PC.  From the PC you can store many methods and keep the data for integrating into a LIMS system.  You can also have the software setup to run the titrations step by step - this is helpful for new techs just learning how to run a titration application.  There are many people who have and like this configuration with the software.  And yes you can attach a newer sample changer (either the CHA500 or CHA600) to the AT-510.  I do think the CHA600 is better because it uses newer pumps.

As for the 600 series, I think it is also very nice.  It's more expensive however if you are only considering purchasing one titrator.      The reason for this is because the 600 series titrator is completely different from the 500 series -stand alone- instrument.  The 600 series has a 8" flat panel/touch panel monitor that is intended to control not only one, but two separate titators (you kind of break even after you buy the less expensive second system).   The AT600 series titrator is very nice with the rich monitor text and graphics but it does not work with the ATWin software and therefore it is what I consider a stand alone unit.  You need to capture data from the unit and manually upload it to your network.  In some ways I think this can be a drawback.  But if you know what you intend to do with the data you can make a decision that best fits your needs.

I hope this helps.  Let me know if you still have questions.

regards.

Well, it seems it is possible where the RS-232 output will drive an xy printer, but I have no
information regarding the exact configuration.  I know this is not the answer you were looking for.  Have you tested this using the RS-232 yet? Let me know.

Hydranal-composite 5 one-component reagent volumetric KF titration
Checked with the manufacturer and unfortunately it can't be done.  Printers still exist if you want to replace it.  I'm actually surprised that there was no other way to get data out of the titrator.  I'm going to do some checking to see if there are any other options available.
I would definately consider an evaporator oven for testing moisture in solids like plastic.  The evaporator oven heats the sample to a temperature where the moisture (bound) is released and carried into the karl fisher titration cell via nitrogen gas..delivering only the water into the vessel (keeping the vessel nice and clean) where the moisture is measured similar to a standard direct injection method.  Saves on wasting reagents too.

First can you tell me about your setup?  Are you using a stand alone karl fisher with a high drift in the cell?  Are you using an evaporator to test moisture in solid samples?  I need to know this to narrow down the problem.  Let me know.

What is your application?
Depending on your application I find that most users find a stand alone unit better for measuring salt.
