The SMARTMAC 400 is a control and calibration unit for SMARTPAT analytical sensors. It offers the most comfortable way to configure and calibrate KROHNE’s digital SMARTPAT sensors for pH, ORP and conductivity on-site. Different customer specific measurement pages for up to 4 different measurands with additional trend graph and summary page provide multiple visualisation options and a high degree of flexibility in process monitoring.
For improved process control, the loop powered unit comes with two freely programmable relays for status, system alarm, limit switch and sensor cleaning control. A second current output for any HART® variable (e.g. temperature) is an added value especially in applications where HART® digital communication is not available.
