Functional Automated Potentiometric Titration System with Controller & Stirrer
Complete with 90-Day Warranty

Tested and functional, this fully-automated titrator can deliver speedier and
more accurate results than any manual process can.

Its companion Metrohm 900 touch controller offers straightforward, no-nonsense
control wrapped up in an intuitive interface, making this system easily accessible
to a worker with any amount of experience.

Complete with a Metrohm 801 stirrer and stand, this pre-owned titration
automation system is set to save your lab time and money.

Initializes & Calibrates

A NLS technician found that the Touch Controller initializes successfully and
alerts the user that the exchange unit is new and the system must be set up.

Upon Touch Controller initialization, the dosimat valve also initializes and
homes. The stirrer was also recognized when plugged in.

We did not test all communication ports, but we have no reason to believe they
won’t function.

All components in this system are in excellent condition.
