Following the introduction of the new interfaces and density sensors in the pricelist, it is important to take care not to confuse old and new products. The new density sensor can be connected to the current interface model as well as the new model, unlike the old density sensor that can only be connected to the old interface.

To avoid any problems, the correct combinations are listed below:

1) Old interface (ACQ210-D) and old sensor (ACQ310-D): OK
2) New interface (ACQ210N-D) and new sensor (ACQ310N-D): OK
3) Old interface (ACQ210-D) and new sensor (ACQ310N-D): OK
4) New interface (ACQ210N-D) and old sensor (ACQ310-D) NO!!!

CAUTION: the new sensor (cases 2 and 3) can only be calibrated using the new calibration solution (code ACQ410-D3). The old sensor (case 1) must be calibrated using the calibration solution with code ACQ410-D2.
