Overview of portable four-gas detector

Overview of portable four-gas detector

Portable four-gas detector is a detection instrument that can detect four target gases at the same time, it is an upgraded version of the traditional single gas detector, which can meet the needs of a variety of gas detection in the modern industrial environment, and some can also be expanded to measure temperature and humidity, atmospheric pressure and other environmental parameters, to achieve a multi-purpose, cost-saving effect. It can be turned on with one key, and can detect the gas concentration in the air in real time without chemical reagents. When the concentration of the measured gas reaches the preset alarm point, it will automatically issue a three-level alarm warning.

Product function characteristics

Calibration function

Such as portable 4-in-1 gas detector with intelligent calibration function, support zero point, target point calibration, reference line adjustment. There are also instrument concentration calibration ministrations can be automatically identified and prevented to avoid human factors caused by bad, and can be calibrated at the target point to ensure the linearity and accuracy of the measurement.

Adapted to special environmental functions

In order to solve the influence of water vapor, some portable four-gas detectors are expanded to add water trap filters, which can be adapted to the detection work in water vapor, oil and gas, dust environment. There are also built-in water vapor and dust filters to prevent damage to sensors and instruments due to water vapor and dust.



Diversification of alarm functions

In addition to the basic sound, light and shock alarm when the gas concentration reaches the preset alarm point, some detectors also have a new anti-fall alarm function, such as an accidental fall will continue to alarm to remind other staff; There are undervaluation alarm, fault alarm, etc., when the alarm is multi-dimensional display alarm status. And alarm value can be set, alarm mode can be selected low alarm, high alarm, interval alarm, weighted average alarm.

Data processing function

Some portable four-gas detectors have large-capacity data storage functions, such as the standard 100,000 data storage capacity, support real-time storage, timing storage, or only store alarm concentration data and time, support the local view, delete data, can also be uploaded to the computer through the USB interface, the upper computer software analysis of data, storage and printing. At the same time, it can record calibration logs, maintenance logs, troubleshooting countermeasures, and sensor life expiration reminder, the next concentration calibration time reminder function.

Display function

Some detectors have high-definition color screen display real-time concentration, alarm, time, storage, communication, electricity, charging status and other information, the menu interface uses high-definition simulation ICONS to display the name of each menu function. There are also three display modes that can be switched, such as displaying four gas concentrations at the same time (optional compound), large-character circulation to display single-channel gas concentration, real-time curve, automatic cycle or manual cycle between channels can be switched, you can set whether to display the maximum value, minimum value, gas name, you can view the history curve.

Charging and power functions

Some detectors use 3.7VDC, 4600mA rechargeable battery, with overcharge, over discharge, over voltage, short circuit protection function, 5-level power display, support USB hot swap, charging interface can be charged by computer or charging bank, compatible with mobile phone charger, the detector can work normally when charging.

Scope of application

Portable four-gas detector is generally widely used in underground pipelines, underground facilities, railways, cargo holds, tunnels, iron and steel plants, chemical plants, coal mines and other fields, and is also very suitable for underground pipe corridors, cellars, sewage ponds, sewers and other limited space places.

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...
