Nitrite ION ION tester is one of the intelligent online chemical analysis instruments. It is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, continuous monitoring of nitrite ion values and water temperature in solutions such as food and

tap water.

Monitoring data through the transmission and output of the recorder to achieve remote transmission monitoring and recording, can also be connected to the RS485 interface through the MODBUS-RTU protocol can be easily connected to the computer to achieve monitoring and recording. At the same

time, the equipment has 2 relay interfaces, and the alarm point output can be set

Features 

This product probe is composed of nitrite ion glass electrode and silver chloride reference electrode composite, signal stability, high precision. With a wide measurement range, good linearity, good waterproof performance, easy to use, easy to install, board modular design, assembly configuration, the use of 2.4 inch 128*64 dot array screen, isolated transmission output, less interference, isolated RS485 communication, can be used for nitrite ion measurement, water temperature measurement, upper and lower limit control, transmission output, RS485 communication, configurable water temperature manual, automatic compensation function, high and low alarm functions can be set, and hysteresis, LCD backlight switch function, increase Universal password function and other features

Product usage topology diagram

typical aqueous solution control system is shown in the figure below, including a set of overall systems with a control box as the core, in which the control box is connected to a nitrite ion probe, and the output acquisition and processing is displayed, and the device can output RS- 485 signal or analog signal to the computer, PLC, microcontroller, etc., while the back end of the relay can the relay can be used for a variety of control and alarm, and can control equipment such as pumps or valves.
