Organic Sensor

Digital COD sensor, based on UV absorption method, adopts LED dual beam structure, measures organic matter concentration in water through UV254nm and 860nm absorbance, 254nm absorbance, and uses 860nm beam to measure turbidity to reduce interference with COD value. The sensor has RS485 output, standard MODBUS protocol, and supports various terminal networking.

Digital ammonia nitrogen sensor, no reagents required, green and pollution-free, can be monitored online in real time. Integrates ammonium ions, potassium ions (optional), pH and reference electrodes, automatically compensates for potassium ions (optional), pH and temperature in the water. Can be directly installed, convenient and quick. The sensor is equipped with a self-cleaning brush to prevent microbial attachment, making the maintenance cycle longer and having excellent reliability. RS485 output, supports Modbus protocol, easy to integrate.

Digital nitrate/ammonia nitrogen composite sensor, developed based on ion selection method, made of industrial-grade nitrate ion selective membrane electrode, selectively tests the nitrate ion content in water, with fast response speed and accurate measurement. Built-in temperature sensor, built-in temperature sensor, automatic temperature compensation, suitable for online long-term monitoring environment. Output RS485 digital signal, support MODBUS protocol.

Full spectrum water quality analyzer, no need for water sample pretreatment, no need for chemical reagents, the sensor can be directly measured by placing it in water. The light source emits full spectrum light from ultraviolet to visible light to the water sample, penetrates the water sample through the mirror window to the diode array detector, accurately subdivides the spectrum to measure different light absorbances, and then analyzes the concentrations of various substances based on the correlation analysis of field tests, experimental data and absorption spectra and various interferences (such as chemicals, turbidity, chromaticity, bubbles, etc.) and advanced algorithms that compensate for each other.

It can simultaneously measure multiple parameters such as CODcr, CODMn, BOD, TOC, SAC, nitrate nitrogen, chromaticity, turbidity/suspended solids, sulfide, chlorophyll a, etc.

The digital oil-in-water sensor uses ultraviolet fluorescence to monitor the oil content in water. It quantitatively analyzes the concentration of oil in water based on the fluorescence intensity emitted by petroleum and its aromatic compounds and conjugated double bond compounds after absorbing ultraviolet light. Aromatic hydrocarbons in petroleum can produce fluorescence under ultraviolet light excitation, and the value of oil in water is calculated based on the intensity of fluorescence. The sensor has RS485 output, standard MODBUS protocol, and supports various terminal networking.

Digital oil-in-water sensor, a digital sensor developed based on the ultraviolet fluorescence optical water quality analysis platform. The sensor emits ultraviolet light of a specific wavelength. When certain petroleum substances in the water sample absorb ultraviolet energy and become excited, they will emit fluorescence when they jump back from the high energy state to the low energy state. The intensity of the excited fluorescence is related to the concentration of the substance to be measured. The sensor has RS485 output, standard MODBUS protocol, and supports various terminal networking.
