Item specifics

Our R&D department no longer uses this piece of equipment. I took it apart to wipe it down and couldn’t figure out how to put it back together. The red tubes and other parts in the photos are just placed; incorrectly I’m sure, for photo purposes. I plugged it up, turned it on, used the down arrow and took a few different photos of the screen. I have no idea how to operate this beast, I’m just the seller. It looks like something found in a scientists laboratory. It’s heavy so you’ll have to pay for the freight. Just the unit itself weighs approx. 30 pounds. If you have any questions email me.


Below is link to a manual to this titrator in a pdf file. I don't have the original manual. The only thing in form of paperwork is the memo card located in one of the photos. *** The following paragraph mentions something about a printer, remote control and other accessories. That is for information purposes only. This unit does not include all those special bells and whistles.









The DL77, DL70 ES, and DL67 METTLER titrators are microprocessor-controlled analytical instruments that provide accurate and reproducible results thanks to their built-in intelligence. With these titrators, you can perform end point, equivalence point and pH-stat titrations, measure pH/mV and temperature, and determine TAN/TBN and p/m values. With the aid of a polarization current source, you can determine water contents by the Karl Fischer method (>2 mg H2O/sample). You can perform conductivity measurements and conductometric titrations with an appropriate non-Mettler unit equipped with an analog output.


All titrators have a maximum of four inputs for electrodes, two for temperature sensors and three 24-V outputs for stirrer, pump or valve attachments. They have a maximum of four RS232C/CL interfaces, enabling you to connect a series of peripheral instruments:


- an attached METTLER balance transfers the sample weight automatically,

- a printer records the desired results,

- a color terminal serves as a second display and can be used for remote control, or a     PC/robot can interchange data with the titrator, and

- with an attached METTLER Sample Changer, each titrator is turned into a titration system for the automatic analysis of whole series of samples.



How the three titrators differ from each other

DL77: Two titrations can be executed simultaneously and two sample changers can be

connected. Neither the DL70ES nor the DL67 allow this.


DL77/ These titrators can control a maximum of four burette drives, the DL67 two.


DL70ES:These instruments know the most important titrants and all METTLER sensors,

whereas the DL67 knows one titrant and one sensor.

With both titrators a maximum of 10 titration methods can be entered in a list and

processed in succession. With the DL67 one method can be entered at a time.

While a titration is running, you can develop and save a new method, or you can

enter sample data for the next titration method. This is not possible with the DL67.
