This manual provides installation, operation, calibration, and maintenance instructions for the Mettler-Toledo 770MAX Multiparameter Analyzer/Transmitter.
The Mettler-Toledo 770MAX is a multiparameter analyzer and transmitter designed for high-accuracy measurement and control. It accepts inputs from up to four Smart Sensors plus two additional pulse flow sensors. Supported parameters include resistivity, conductivity, pH, ORP, dissolved oxygen, dissolved ozone, TOC, flow, temperature, and pressure. The device supports derived measurements such as total dissolved solids, % rejection, and calculated pH. It features standard outputs including four isolated analog signals, RS232, and two TTL discrete output ports, with optional additional analog signals and relays available.

The 770MAX accepts inputs from up to four Smart Sensors plus two additional pulse flow sensors.
No, Smart Sensors used with the previous generation 770PC instrument are not compatible with 770MAX due to signal processing and connector differences.
Standard outputs include 4 isolated analog (0/4-20 mA) signals, RS232, and two TTL discrete output ports.
