Large display, standard 485 communication, with online and offline alarm, 144*144*118mm meter size, 138*138mm hole size, 4.3 inch large screen display.
Intelligent menu operation
Multiple automatic calibration
Differential signal measurement mode, stable and reliable
Manual and automatic temperature compensation
Three relay control switches
4-20mA & RS485,Multiple output modes
Multi parameter display simultaneously shows – pH,EC,FCL/turbidity, Temp, current,etc.
Password protection to prevent misoperation by non staff.
The matching installation accessories make the installation of the controller in complex working conditions more stable and reliable.
High & low alarm and hysteresis control. Various alarm outputs. In addition to the standard two-way normally open contact design, the option of normally closed contacts is also added to make the dosing control more targeted.
The 3-terminal waterproof sealing joint effectively prevents water vapor from entering, and isolates the input, output and power supply, and the stability is greatly improved. High resilience silicone keys, easy to use, can use combination keys, easier to operate.
The outer shell is coated with protective metal paint, and safety capacitors are added to the power board, which improves the strong magnetic anti-interference ability of industrial field equipment. The shell is made of PPS material for more corrosion resistance. The sealed and waterproof back cover can effectively prevent water vapor from entering, dustproof, waterproof, and corrosion-proof, which greatly improves the protection capability of the whole machine.
