Detailed introduction
product description:
LD-3650 is a classic industrial online pH / ORP controller, which has provided continuous and accurate online measurement on thousands of projects at home and abroad.
LD-3650 is widely used in various occasions that require precise measurement and control of pH (or redox potential ORP), helping users to achieve process control, environmental protection standards and energy saving. After continuous improvement, it has become a very stable product, and it is the product of choice for users in various industries to achieve precise control at low cost.
Performance characteristics:
1. Stable and reliable performance, beautiful appearance and easy operation
2.Large screen backlight full-view LCD display
3. The input impedance is ≥1012Ω, and the anti-interference performance is good. It can adapt to the special use conditions of the signal line up to 50 meters.
4, with high and low point alarm and electrode cleaning prompt indicator
5, IP65 protection level, suitable for relatively harsh use occasions
6, economical and affordable, can be adapted to various industrial manufacturers of domestic and foreign composite pH / ORP electrodes
7, wide power supply design, you can choose to switch pH or ORP measurement mode, more in line with the needs of the project
