Product Overview:
Conductivity sensor, strong environmental adaptability, clear display, easy operation and excellent test performance make it very cost-effective. It can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, biochemical, food and tap water and other solutions for continuous monitoring.
Functional features:
High intelligence: It adopts high-precision AD conversion and microprocessing technology, which can complete various functions such as conductivity and resistivity values, temperature measurement, and automatic temperature compensation.
Time display: Chinese online conductivity meter has a built-in clock chip, which can display the current time.
Data storage: The memory chip built into the instrument can save historical data from the past two days, making it easy for users to find.
Flushing relay: The instrument is equipped with a flushing relay, which can clean the conductivity electrode regularly by installing a solenoid valve.
25°C conversion: The conductivity value at the current temperature is converted to 25°C, which realizes the display of the conductivity value at 25°C, which is suitable for the measurement of various water quality in power plants.
Strong anti-interference ability: new devices with impedance up to 10-12Ω; The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and realizes long-distance transmission. It has good electromagnetic compatibility.
Simultaneous display of multiple parameters: The time, conductivity value or resistivity value, temperature, and output current value are displayed simultaneously on the LCD screen. It adopts a high-brightness 128*64 LCD display module, which is eye-catching and has a long viewing distance.
RS485 communication interface: MODBUS RTU communication protocol can be easily connected to a computer for monitoring and communication.
Industrial-controlled watchdogs: Make sure the meter doesn't freeze.
