Key parameters
Measuring range
Multiparameter transmitter; CM444 up to 4 Memosens inputs (pH/ORP, conductivity, DO, chlorine, turbidity, etc. per sensors)
Accuracy
Measurement accuracy depends on connected Memosens sensor; TI gives current I/O error tables
Output
Active current outputs (optional HART); relays; HART/PROFIBUS DP/Modbus/EtherNet/IP/PROFINET; web server
Supply
CM444: 100–230 VAC 50/60 Hz (±15%) max 73 VA; or 24 VDC max 68 W
Housing
Field housing (polycarbonate class) per TI mechanical construction
Protection
IP66/67 (IEC 60529); NEMA Type 4X (UL 50E)
