pH Sensor
PH is a crucial indicator for monitoring industrial wastewater. In industrial wastewater, the variation range of most microorganisms is pH 4.5-9, and the optimum pH range is 6.5-7.5. When the pH value is beneath 6.5, fungi begin to compete with bacteria. When pH reaches four.5, the micro organism will dominate within the biochemical tank and seriously have an result on the sludge settling. When the pH worth exceeds 9, the metabolic price of microorganisms shall be hindered.
In order to observe the PH worth of industrial wastewater, we usually use PH sensors. PH sensors are sensors that are used to watch the focus of hydrogen ions within the measured solution and convert it right into a corresponding usable output sign. It is appropriate for industrial wastewater, home wastewater, agriculture, aquaculture and other non-corrosive weak acidic and weak alkaline surroundings eventualities.
ORP Sensor
Redox potential (ORP) is a crucial indicator to measure the quality of aquaculture water, ORP worth can reflect the nice or unhealthy water high quality. The bigger the ORP worth, the stronger the oxidation of the water physique, the smaller the worth, the stronger the discount of the water body.
The ORP sensor is especially used because the oxygen reduction potential of an answer. It can detect ORP data not solely in water, but also in soil and culture media. Therefore, it’s also a widely used sensor for steady monitoring of varied water ORP in electric power, chemical, environmental safety, pharmaceutical, meals and different industries. Usually, will probably be used along with PH sensor.
Conductivity Sensor
Conductivity is the flexibility to conduct electric current in a physique of water. In water high quality monitoring, conductivity is certainly one of the necessary indicators to reflect water high quality. The greater the conductivity worth of water, the better the conductivity, the higher the TDS value in water. the TDS worth represents the content of dissolved impurities in water. the greater the TDS worth, the larger the content material of impurities in water. Conversely, the smaller the impurity content, the greater the water. Pure, the decrease the conductivity.
Conductivity sensors may be divided into electrode conductivity sensors, inductive conductivity sensors and ultrasonic conductivity sensors in accordance with the totally different measurement rules. Electrode conductivity sensors use resistance measurement technique based on electrolytic conduction precept. Inductive conductivity sensors are primarily based on the precept of electromagnetic induction to attain the measurement of liquid conductivity. Ultrasonic conductivity sensors measure conductivity based on the change of ultrasonic waves in liquids, and the first two sensors are extra extensively used.
Apure sensor adopts electrode sort conductivity measurement technique with built-in high precision sensor, excessive accuracy, conductivity measurement vary between 0~20,000μS/cm, measurement error is ±1%FS, high sensitivity. This conductivity sensor comes with a cable related 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 carefully associated to the partial stress of oxygen within the air and the temperature of water. Under pure circumstances, the oxygen content in the air doesn’t change much, so the water temperature is the main issue, the lower the water temperature, the upper the dissolved oxygen content in the water. The molecular oxygen dissolved in water is called dissolved oxygen, normally 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 physique.
There are two primary kinds 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.

The residual chlorine sensor KCL is used to measure residual chlorine, chlorine dioxide and ozone in water. The electrode structure is simple and simple to clean and exchange. It can be utilized in drinking water therapy vegetation, canneries, drinking water distribution networks, swimming swimming pools, cooling circulating water, water high quality remedy tasks, and so forth. where the residual chlorine content in aqueous solutions needs to be constantly monitored.
Turbidity Sensor
Turbidity is brought on by suspended particles in the water. The suspended particles diffusely mirror the incident gentle. Scattered mild within the ninety diploma path is often used because the check sign. The scattered gentle and turbidity are linear in multiple segments, so the sensor must be calibrated at multiple points.
The KS-710 turbidity sensor is designed and manufactured using the precept of scattered gentle turbidity measurement. It accurately measures the quantity of light passing by way of the water body to precisely measure the suspended matter within the water, which might mirror the air pollution of the water physique.

Commonly used in water high quality detector for correct 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 can’t be measured immediately, so with the change and improvement of salinity measurement strategies, the corresponding definition of salinity is introduced in practical application.
Salinity sensors are used to measure the salinity of liquids and options and are able to measuring the whole range from 24 to 52,000 ppm (parts per million). Salinity is the sum of all non-carbonate salts dissolved in water and is usually expressed in elements per thousand (1 ppm = 1000 mg/L). Salinity is a vital measurement in seawater. The salinity degree in seawater is fairly fixed at about 35 ppm (35,000 mg/L).
Ozone Sensor
Ozone is a kind of allotrope of oxygen, chemical formula is O3, method 47.998, a light-weight blue fuel with fishy odor. Ozone has robust oxidation, is a stronger oxidant than oxygen, oxidation reaction can happen at decrease temperatures, similar to silver oxidation into silver peroxide, lead sulfide oxidation into lead sulfate, with potassium iodide reaction to generate iodine. Turpentine, gasoline, and so forth. can spontaneously ignite in ozone.
Ozone meter is the precept of ultraviolet absorption methodology, with secure ultraviolet mild source to provide ultraviolet mild, with mild wave filter out other wavelengths of ultraviolet gentle, only allow wavelength 253.7nm through. After passing through the pattern photoelectric sensor, and then by way of the ozone absorption tank, it reaches the sampling photoelectric sensor. By comparing the electrical signals of the pattern photoelectric sensor with these of the pattern photoelectric sensor, and then calculating the mathematical model, the ozone focus may be obtained.
Chemical Oxygen Demand (COD) Sensor
Many organic substances dissolved in water take up UV mild. Therefore, by measuring the degree of absorption of UV gentle at 254 nm by these organic substances, the amount of dissolved organic contaminants in water can be precisely measured.
The Apure COD sensor makes use of two gentle sources, an ultraviolet mild for measuring the COD content in water and a reference gentle for measuring the turbidity of the water physique, with the light path attenuation being compensated for by a selected algorithm and out there to some extent. Eliminate the interference of particulate suspended impurities, thus attaining extra steady and dependable measurement.
Ammonia Nitrogen Ion (NH3-N)Sensor
In aquaculture, if the ammonia nitrogen level within the water is simply too excessive, it’s going to poison the fish and shrimp and cause them to die. Therefore, water high quality ammonia hydrogen sensors are especially needed for monitoring ammonia nitrogen focus. Ammonia nitrogen sensors are used to measure the ammonia nitrogen content material of water quality and are commonly used within the fields of Internet of Things, aquaculture, and smart agriculture.
