Portable water quality tester overview

First, portable water quality tester overview

Portable water quality tester is a special instrument used to detect a variety of physical and chemical indexes of aqueous solution. It has the characteristics of compact and portable, and can be used for water quality detection in a variety of scenarios, and plays an important role in ensuring water quality safety.

Second, the characteristics of portable water quality tester

(1) Measurement function

Multi-parameter testing: Many portable water quality testers can carry out multi-parameter water quality testing, such as detecting residual chlorine, total chlorine, COD, ammonia nitrogen, total phosphorus, total nitrogen, metal elements, chroma, chloride, ozone, PH, conductivity, dissolved oxygen, turbidity and other water quality indicators, without using a variety of large instruments for different indicators, convenient and fast.

Accuracy: Some of the imported ultra-bright LED light source and detector, advanced light source driving and calibration technology to ensure long-term stability, accuracy and a wider measurement range of the instrument, as well as imported photoelectric converters to further ensure the accuracy and stability of the measurement.



(2) Operation and use

Simple operation: The general operation is simple, some in the use of supporting reagents, do not need to prepare a standard solution, draw a standard curve, can directly put the sample or diluted solution into the instrument for quantitative water quality testing, the key design is reasonable, such as silicone keys to ensure sealing performance at the same time has a long service life, easy to operate.

Portability: small size, light weight, easy to carry, suitable for field sampling, field detection and other situations. And some instruments can use battery power, such as two 1.5V batteries can be used to work continuously for 72 hours, or the use of low-power design with large-capacity rechargeable lithium batteries can work continuously for 7 days on a single charge, standby time of up to 15 days, and the instrument charging bank or mobile phone charger can be powered, solving the problem of outdoor charging equipment.

(3) Data processing

Data storage and call: can be in the field or laboratory for data storage and call data recording, some instruments can automatically infinite storage data (can be accurate to the time, date, parameters, numbers, results), but also at any time to call the various stages of the data, and some with USB interface convenient connection to the computer to transfer data.

Effects of natural gas leakage on the human body

图片
The effects of natural gas leakage on the human body depend on factors such as the amount of leakage, exposure time, and personal physical condition. The specific effects are as follows: Acute health effects Hazard of suffocation The main component of natural gas is methane. If the concentration in the air is too high, it will reduce the oxygen concentration and cause suffocation. When people are in such an environment, the body will experience symptoms such as difficulty breathing and dizziness due to lack of oxygen. In severe cases, it may lead to coma or even death. Irritation Natural gas may contain toxic gases such as hydrogen sulfide, which irritates the human respiratory tract, causing symptoms such as difficulty breathing and coughing. If you are in an environment containing such gases for a long time, the respiratory tract will be continuously irritated and the damage will be aggravated. Explosion and fire risks After natural gas leaks, once it encounters open flames or high t...

The impact of air quality on health

Impact on the Respiratory System Air pollution is particularly harmful to the respiratory system. Particulate matter (such as PM2.5 and PM10) can enter the respiratory tract, irritating the nose and throat, causing symptoms such as coughing, wheezing, and difficulty breathing. Long-term exposure can increase the incidence of chronic obstructive pulmonary disease (COPD), bronchitis, and asthma. Furthermore, pollutants damage the alveoli and respiratory mucosa, reducing lung ventilation and air exchange, decreasing vital capacity, and gradually weakening lung function, affecting the body's breathing capacity and endurance. Impact on the Cardiovascular System Particulate matter and other particles in air pollution can enter the bloodstream, triggering inflammation and oxidative stress, promoting the formation of atherosclerotic plaques, and increasing the risk of cardiovascular diseases such as coronary heart disease, myocardial infarction, and stroke. Pollutants can also affect the ...

The role of chlorine sensors in agricultural automation

In the field of agricultural automation, although chlorine is not as well known as soil nutrients, temperature and humidity, it will have an impact on agricultural production in certain scenarios. Chlorine sensors can also play an important role. The following explains their roles from different aspects:   Ensure agricultural water safety Monitor irrigation water quality In some areas, water disinfected with chlorine may be used for agricultural irrigation. Chlorine sensors can monitor the chlorine content in irrigation water in real time to ensure that it is within a safe range, avoid damage to crops due to excessive chlorine content, and affect crop growth and yield.   Prevent water pollution If the source of agricultural water is polluted by industrial wastewater, it may contain excessive chlorine. Chlorine sensors can detect this abnormality in time and remind farmers to take corresponding measures, such as changing the water source or further treating the water, to ensur...
