Metrohm 702 SM Titrino Titrator with 728 Stirrer
We've tested this titration system and can confirm that it will work for you once you supply a new exchange unit, as the current cable is missing a pin and does not function properly as a result.
All components of this titration stirrer are in good condition and are backed by a 90-day warranty.
After applying a temporary fix to the exchange cable, we tested this system with the following results:
- 702 SM Titrino external keypad works: PASSED
- Buttons and dV/dt dial on 702 SM Titrino works: PASSED
- 728 stirrer works properly: PASSED
- Tubing is in good condition: PASSED
Notice: You must supply a new exchange unit in order for the 702 SM Titrino to function properly.
Though there are some signs of wear, this titration system is in good condition overall. We recommend reviewing the photos for a full understanding of what you'll receive.
