Mettler-Toledo 770MAX Multiparameter Analyzer Instruction Manual
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.
