Introduction of Portable Dissolved Oxygens Detector: Dissolved oxygens analyzer is based on electrochemical principles. That is, on two different metal electrodes in the measured electrolyte solution containing oxygen. Oxidation-reduction reaction will occur, and the resulting diffusion current has a certain relationship with the oxygen concentration in the solution. It is an instrument for measuring the […]

Overview gas detector pid PhotoIonization Detector (PID for short). It is a detector with extremely high sensitivity and a wide range of applications. It can detect volatile organic compounds (Volatile Organic Compounds, referred to as VOC) from very low concentrations of 1000 ppb to higher concentrations of 2000 ppm. Compared with traditional detection methods, it

Ozone is an allotrope of oxygen, a light blue gas with a fishy smell. Ozone has strong oxidizing properties and is a stronger oxidant than oxygen. It can be oxidized at a lower temperature. For example, it can oxidize silver to silver peroxide, and lead sulfide to lead sulfate, which reacts with potassium iodide to

Hydrogen sulfide is an inorganic compound with a molecular formula of H2S and a molecular weight of 34.076. Under standard conditions, it is a flammable acid gas. It is colorless and has the smell of rotten eggs at low concentrations. The aqueous solution is hydrogen sulfuric acid, which is weaker than carbonic acid, but stronger

Background The ultrasonic wind speed and direction sensor is a wind measurement instrument developed based on the principle of ultrasonic. Using the transmitted sound wave pulse, the time or frequency difference at the receiving end is measured to calculate the wind speed and direction. It is widely used in the measurement of wind direction and

Rain and snow sensors under weather monitoring systems Rainfall is the condensation of water vapor in the atmosphere caused by atmospheric circulation disturbances. And the phenomenon of falling to the ground in the form of liquid or solid water. The liquid is rain, and the solid is snow or hail. Rain and snow are all

Overview: wifi weather station: wind speed. wind direction. Air temperature. Air humidity. Soil temperature. Soil moisture. rainfall. Total radiation. Air pressure. Sensors such as evaporation (can be configured according to user needs). The weather station consists of weather sensors. Microcomputer meteorological data acquisition instrument. Power Systems. Radiation protection hood. All-weather protective box and weather observation

Overview: The purpose of observation of greenhouse indoor weather station is to understand the meteorological effects of greenhouse measures. The microclimate performance of the greenhouse. It is also suitable for parallel observation of crop greenhouse environment. To determine the agro-meteorological indicators of crops or the microclimate effect of greenhouse regulation measures. It can also be

Overview: ambient weather station is in accordance with the International Meteorological WMO Organization’s meteorological observation standards. A multi-element automatic weather station developed and produced by research. It can monitor conventional meteorological elements such as wind direction, wind speed, temperature, humidity, air pressure, rainfall, soil temperature and humidity. With automatic recording. Functions such as over-limit alarm

Background: With the improvement of people’s material level, people pay more and more attention to the quality of life. People grow flowers and plants themselves, and cultivate flowers. The soil is the basis for the growth of flowers. The soil can store abundant nutrients and microorganisms for a long time. It continuously provides energy for
