pH Sensor
PH is an important indicator for monitoring industrial wastewater. In industrial wastewater, the difference range of most microorganisms is pH 4.5-9, and the optimum pH range is 6.5-7.5. When the pH worth is under 6.5, fungi start to compete with bacteria. When pH reaches four.5, the bacteria will dominate in the biochemical tank and critically have an result on the sludge settling. When the pH worth exceeds 9, the metabolic rate of microorganisms might be hindered.
In order to monitor the PH worth of industrial wastewater, we generally use PH sensors. PH sensors are sensors which may be used to watch the concentration of hydrogen ions in the measured resolution and convert it into a corresponding usable output sign. It is suitable for industrial wastewater, home wastewater, agriculture, aquaculture and other non-corrosive weak acidic and weak alkaline environment scenarios.
ORP Sensor
Redox potential (ORP) is a vital indicator to measure the quality of aquaculture water, ORP worth can reflect the great or dangerous water quality. The larger the ORP worth, the stronger the oxidation of the water body, the smaller the value, the stronger the discount of the water physique.
The ORP sensor is principally used as the oxygen discount potential of a solution. It can detect ORP knowledge not only in water, but additionally in soil and culture media. Therefore, additionally it is a widely used sensor for continuous monitoring of varied water ORP in electrical energy, chemical, environmental protection, pharmaceutical, food and different industries. Usually, will in all probability be used together with PH sensor.
Conductivity Sensor
Conductivity is the power to conduct electrical present in a body of water. In water high quality monitoring, conductivity is considered one of the essential indicators to mirror water quality. The higher the conductivity worth of water, the better the conductivity, the higher the TDS worth in water. the TDS value represents the content of dissolved impurities in water. the greater the TDS worth, the higher the content material of impurities in water. Conversely, the smaller the impurity content, the greater the water. Pure, the lower the conductivity.
Conductivity sensors could be divided into electrode conductivity sensors, inductive conductivity sensors and ultrasonic conductivity sensors according to the totally different measurement rules. Electrode conductivity sensors use resistance measurement methodology based mostly on electrolytic conduction precept. Inductive conductivity sensors are based mostly on the precept of electromagnetic induction to realize the measurement of liquid conductivity. Ultrasonic conductivity sensors measure conductivity primarily based on the change of ultrasonic waves in liquids, and the first two sensors are extra broadly used.
Apure sensor adopts electrode sort conductivity measurement technique with built-in excessive precision sensor, excessive accuracy, conductivity measurement range between 0~20,000μS/cm, measurement error is ±1%FS, excessive sensitivity. This conductivity sensor comes with a cable connected to a transmitter that sends the signal to processing and/or recording gear.
Dissolved Oxygen (DO) Sensor
The molecular oxygen within the air dissolved in water is called dissolved oxygen. The content of dissolved oxygen in water is intently related to the partial strain of oxygen within the air and the temperature of water. Under pure circumstances, the oxygen content material within the air doesn’t change a lot, so the water temperature is the main factor, the decrease the water temperature, the higher the dissolved oxygen content material in the water. The molecular oxygen dissolved in water known as dissolved oxygen, usually denoted as DO, and is expressed in milligrams of oxygen per liter of water. The quantity of dissolved oxygen in water is an index to measure the self-purification capability of water body.
There are two major types of Apure dissolved oxygen sensors, KOG-202S Polarographic Dissolved Oxygen Sensor and KOG-206 Optical Dissolved Oxygen Sensor. Continuous detection of dissolved oxygen in liquid.
Residual Chlorine Sensor
Residual chlorine is the overall time period for the free and sure chlorine remaining in the water after chlorination disinfection and exposure for a sure period of time.
The residual chlorine sensor KCL is used to measure residual chlorine, chlorine dioxide and ozone in water. The electrode structure is easy and straightforward to clean and substitute. It can be utilized in drinking water treatment crops, canneries, ingesting water distribution networks, swimming pools, cooling circulating water, water high quality remedy tasks, and so on. where the residual chlorine content in aqueous solutions must be constantly monitored.

Turbidity is brought on by suspended particles within the water. The suspended particles diffusely reflect the incident gentle. Scattered light in the 90 degree direction is often used as the test signal. The scattered mild and turbidity are linear in multiple segments, so the sensor needs to be calibrated at a quantity of factors.
The KS-710 turbidity sensor is designed and manufactured utilizing the principle of scattered mild turbidity measurement. It precisely measures the amount of sunshine passing via the water body to precisely measure the suspended matter within the water, which may replicate the air pollution of the water body. In this fashion the turbidity in the water pattern is measured and the final value is output after linearization. Commonly used in water quality detector for accurate measurement of rivers, sewage, wastewater.
Salinity Sensor
Absolute salinity is the ratio of the mass of dissolved matter in sea water to the mass of sea water. Absolute salinity cannot be measured immediately, so with the change and improvement of salinity measurement methods, the corresponding definition of salinity is introduced in practical application.
Salinity sensors are used to measure the salinity of liquids and options and are capable of measuring the complete range from 24 to 52,000 ppm (parts per million). Salinity is the sum of all non-carbonate salts dissolved in water and is often expressed in components per thousand (1 ppm = a thousand mg/L). Salinity is an important measurement in seawater. The salinity level in seawater is pretty constant at about 35 ppm (35,000 mg/L).
Ozone Sensor
Ozone is a type of allotrope of oxygen, chemical formula is O3, formula forty seven.998, a light blue fuel with fishy smell. Ozone has sturdy oxidation, is a stronger oxidant than oxygen, oxidation reaction can happen at lower temperatures, corresponding to silver oxidation into silver peroxide, lead sulfide oxidation into lead sulfate, with potassium iodide reaction to generate iodine. Turpentine, fuel, and so on. can spontaneously ignite in ozone.
Ozone meter is the precept of ultraviolet absorption technique, with stable ultraviolet mild supply to provide ultraviolet gentle, with gentle wave filter out other wavelengths of ultraviolet mild, only allow wavelength 253.7nm by way of. After passing by way of the sample photoelectric sensor, and then by way of the ozone absorption tank, it reaches the sampling photoelectric sensor. By comparing the electrical indicators of the sample photoelectric sensor with those of the pattern photoelectric sensor, and then calculating the mathematical model, the ozone concentration could be obtained.
Chemical Oxygen Demand (COD) Sensor
Many organic substances dissolved in water take up UV light. Therefore, by measuring the diploma of absorption of UV light at 254 nm by these natural substances, the quantity of dissolved natural contaminants in water could be precisely measured.

Eliminate the interference of particulate suspended impurities, thus reaching extra stable and dependable measurement.
Ammonia Nitrogen Ion (NH3-N)Sensor
In aquaculture, if the ammonia nitrogen level within the water is just too excessive, it will poison the fish and shrimp and cause them to die. Therefore, water high quality ammonia hydrogen sensors are particularly needed for monitoring ammonia nitrogen concentration. Ammonia nitrogen sensors are used to measure the ammonia nitrogen content material of water quality and are generally used within the fields of Internet of Things, aquaculture, and smart agriculture.
Apure ammonia nitrogen sensors are manufactured from ammonium ion selective electrodes based on PVC membranes. It is used for ammonium ion content material testing in water with temperature compensation, making certain quick, simple, accurate and economical testing.
