Features
● High intelligence: Adopting high-precision AD conversion and single-chip micro-processing technology, which complete various functions such as residual chlorine value measurement or ozone measurement.
● Time display: Built-in clock chip can display the current time.
● Data storage: The built-in storage chip which could save historical data for 1 year, and the data could be exported through the mobile phone APP Bluetooth (optional function).
● Flushing relay: The instrument is equipped with a flushing relay function, and the electrode can be cleaned regularly by installing a solenoid valve.
● High and low alarm function: The instrument has a built-in buzzer and high and low alarm lights, which can sound and light alarm at the same time when the requirements are met.
● 4-20mA current: The current value can be set arbitrarily and set in reverse, which is easy to control.
● Interval control function: The instrument has an interval relay control function within any range, which can be used for example, interval compliance function, etc.
● Random numerical value function: The meter can displaying random numerical values within any range, which can meet the numerical display function under specific requirements (for specific use, please contact us for details).
● Strong anti-interference ability: It adopts high-resistance operational amplifier with impedance up to 1012 Ω, the current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and can achieve remote transmission. It has good electromagnetic compatibility.
● RS485 communication interface: Modbus RTU communication protocol can be easily connected to the computer for monitoring and communication. (Optional function)
● Industrial control watchdog: Ensure that the instrument will not crash.
Applications
