Features

1. 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.

2. Intelligent menu operation

3. Multiple automatic calibration

4. Differential signal measurement mode, stable and reliable

5. Manual and automatic temperature compensation 6. Three relay control switches

7. 4-20mA & RS485,Multiple output modes

8.Multi parameter display simultaneously shows – pH/DO, Temp, current,etc.

9. Password protection to prevent misoperation by non- staff.

10. The matching installation accessories make the installation of the controller in complex working conditions more stable and reliable.

11. 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.

12. 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.

13.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.

Electrical connections

Electrical connection The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the connection between the sensor and the instrument are all inside the instrument. The length of the lead wire for the fixed electrode is usually 5-10 meters, and the corresponding label or color on the sensor Insert the wire into the corresponding terminal inside the instrument and tighten it.

Digital Dissolved Oxygen Sensor

Introduction:

Dissolved oxygen sensor uses fluorescence measurement of dissolved oxygen, blue light emitted by the phosphor layer, a fluorescent substance is excited to emit red light,and the fluorescent substance and the concentration of oxygen is inversely proportional to the time back to the ground state. The method uses a measurement of dissolved oxygen, no oxygen consumption measurement, the data is stable, reliable performance, there is no interference, installation and calibration simple. Widely used in sewage treatment plants each process, water plants, surface water, industrial process water production and wastewater treatment, aquaculture and other industries on-line monitoring of DO.

Features:
