A005-1 pH/ORP Controller
Order No.
A005-1: controller without sensor
A005-1F: controller with sensor
Features:
1. Board of modular design makes the assembly and configuration more convenient.
2. 2.4 inch 12864 lattice screen is adopted.
3. Isolated transmitting output is adopted so as to make the interference degree smaller.
4. Isolated RS485 communication is adopted.
5. The measurement, temperature measurement, top and bottom limitation control, transmitting output and RS485 communication of PH/ORP is performed.
6. Function of configurable manual or automatic temperature compensation.
7. High and low warning function as well as retardation can be set.
8. The buzzer and LCD backlight switch function can be set.
9. The function of all-powerful password is added.
10. The watchdog of industrial control can guarantee that the instrument won’t crash.
