NTU-1800 Water Quality Test Online Turbidity Tester
Turbidity is the expression of suspended objects in water to the degree of obstruction of light transmission. This product uses RS485 interface to communicate with the digital sensor, high data accuracy, strong anti-interference, can directly control the digital sensor calibration and automatic cleaning and other functions.
◇ Large screen dot matrix LCD display, support English and Chinese menus (switch between each other).
◇ Built-in bubble elimination system (flow type) to improve measurement accuracy and stability.
◇ Good reproducibility, not affected by sample flow rate and pressure (input).
◇ The use of stable invisible near-monochromatic infrared light source, to avoid the color in the liquid and external visible light on the sensor measurement interference; And built-in luminosity compensation, improve the measurement accuracy.
◇ With water storage function, to ensure that the sensor internal flow tank 24 hours water sample (flow type).
◇ Adopt the latest detection technology to avoid the interference of external light, strong anti-interference ability (sinking type).
◇ The quartz glass lens with high transmittance is used in the optical path, and the emission and reception of infrared light waves are more stable.
◇ Communication function (optional) : with RS-485 communication interface (partially compatible with MODBUS protocol), the corresponding value of 4-20 mA current output can be set arbitrarily.
◇ Photoelectric isolation 4-20mA current output.
◇ Arbitrary setting function of hysteresis, to avoid frequent action of switching relay, with setting switching and closing function.
◇ Adopt multi-point correction method.
◇ Automatic cleaning interval can be set freely (sensor support is required).
◇ Watchdog function: ensure that the meter will not crash.
◇ Core devices are from foreign brands.
◇ Power failure protection > 10 years.
