Description
1.Introduction
The Multi-Parameter Water Quality Controller is an online monitoring device that combines multiple parameter monitoring functions.The device can automatically identify different types of digital sensors of our company, including dissolved oxygen probe, turbidity probe, COD, pH probe, conductivity salinity probe, sludge concentration probe, chlorophyll, ammonia nitrogen, ORP, blue-green algae and oil in water probe, with built-in air pressure sensor, which is truly simple and easy to use.
The device supports one RS485 output and one 4-20mA output, photoelectric isolation, and strong anti-interference ability. One RS485 digital output is convenient for users to network. Two isolated relay outputs, users can set the relay function to control the switch state and switch cycle of the device.
The transmitter hardware version number for this document is 2.0 and above.
2.Features
- Automatic identification, plug and play, supports all our digital sensors;
- One 4-20mA output, one RS485 digital output;
- With relay control, users can set the alarm upper and lower limits and cycle;
- Industrial standard, output isolation, strong anti-interference ability.
