The Core Value of Electrochemical Carbon Monoxide Sensor

21th Jan 2026

Carbon monoxide (CO), a colorless and odorless “invisible killer,” lurks in home gas stoves, industrial workshops, traffic environment and other scenarios. Excessive exposure can lead to poisoning and even death. Data shows that over a million cases of CO poisoning occur globally each year, making effective CO detection crucial for risk prevention—ELECTROCHEMICAL CARBON MONOXIDE SENSOR, with its precise monitoring capabilities, have become a core device for safeguarding lives.   Compared to semiconductor and infrared sensors, electrochemical carbon monoxide sensor shows irreplaceable advantages. Its working principle is to convert CO concentration into a precise current signal through an electrochemical reaction, achieving quantitative detection according to Faraday’s law. It possesses extremely high specificity for CO, avoiding false alarms caused by interfering gases such as perfumes and cooking fumes. A low-concentration detection resolution of 1ppm enables early warning of danger; a rapid response time of <25 seconds and a service life of 3 years balance timeliness and durability. In home, electrochemical carbon monoxide sensor can be embedded in gas alarms to monitor the risk of leaks in water heaters and gas stoves 24/7. In industrial workshops, it can monitor CO emissions from boiler combustion and chemical production in real time, helping companies achieve...

S4OXV Oxygen Sensor – Accurate Industrial O2 Detection

14th Jan 2026

Oxygen, a colorless, odorless, and slightly soluble gas essential for life, is chemically stable at room temperature but can react directly with various elements in high-temperature environments. OXYGEN SENSOR leverages these core characteristics to accurately monitor oxygen concentration in various scenarios. Due to its combustion-supporting and strong oxidizing properties, oxygen is widely used in core industrial sectors such as steel smelting, machinery manufacturing, chemical production, defense, aerospace, and healthcare. Oxygen constitutes approximately 21% of the standard volume of air. Accurate detection of oxygen concentration is crucial for mitigating safety risks and ensuring the quality of industrial production. This is precisely the core application value of oxygen sensor—by monitoring oxygen concentration in real time, providing early warnings of potential hazards such as oxygen deficiency and explosions, and simultaneously controlling the concentration to achieve quality management in industrial production. I. Preventing Oxygen Deficiency/Excessive Oxygen Content Risks: In confined spaces, underground tunnels, ship cabins, and other environments with limited ventilation, oxygen deficiency is highly likely, directly threatening the lives of workers. In processes with stringent oxygen concentration requirements, accurate detection of residual oxygen is also a necessary prerequisite for production. Oxygen sensor enables real-time monitoring of oxygen concentration in such scenarios, ensuring operational...

Hazardous Gas Sensors Protect the Safety of the Chemical Industry

08th Jan 2026

   The HAZARDOUS GAS SENSORS are primarily used to detect toxic gases commonly found in the chemical industry. In different scenarios, toxic and hazardous gases mainly generate from raw material reactions, solvent evaporation, leaks, and incomplete combustion of fuels. They can be categorized by toxicity level as follows:   First, highly toxic gases: Most dangerous, inhalation of even small amounts can be fatal. Common gases: Hydrogen sulfide (H2S), hydrogen cyanide (HCN), chlorine (Cl2), etc. Common scenarios: Wastewater treatment plants, desulfurization towers, pesticide production lines, etc. Countermeasures: Hazardous gas sensors based on electrochemical principles. Second, highly toxic gases: Long-term exposure or short-term exposure to high concentrations can also lead to serious harm. Common gases: Carbon monoxide (CO), ammonia (NH3), formaldehyde (CH2O), hydrogen fluoride (HF), etc. Common scenarios: Boiler rooms, nitrogen fertilizer plants, paint workshops, etc.. Precautions against carbon monoxide, formaldehyde are also necessary in daily life. Countermeasures: Electrochemical Series-4 hazardous gas sensors   Third, toxic gases: Primarily irritating and corrosive; long-term exposure can lead to chronic damage. Common gases: Sulfur dioxide (SO2), nitrogen oxides (NOₓ), hydrogen chloride (HCl), etc. Common scenarios: Sulfuric acid plants, boiler exhaust, metallurgical workshops, pickling workshops, etc. Countermeasures: Electrochemical principle hazardous gas sensor Fourth, flammable, explosive and toxic gases: possessing both explosion risk...

Advantages and Disadvantages of Common Gas Sensors

24th Dec 2025

In addition to those mentioned previously, the following four COMMON GAS SENSORS are also in widely use. Today we shall briefly outline their respective advantages and disadvantages. 1. Photoionisation Gas Sensor Working Principle: Utilises ultraviolet light to ionise gas molecules, with the resulting ion current being proportional to gas concentration. Advantages: Extremely high sensitivity, capable of detecting volatile organic compounds (VOCs) at parts-per-billion (ppb) levels; Rapid response time, enabling real-time monitoring; Non-destructive detection, as ionised gas molecules can be reduced. Disadvantages: Incapable of detecting gases with high ionisation energy (e.g., CO, CO₂); UV lamps have a limited lifespan (typically several thousand hours); Relatively high cost. Applications: Environmental VOC monitoring, leak detection in chemical industrial parks, precise indoor formaldehyde detection. 2. Laser Gas Sensors Operating Principle: Utilises laser light sources (e.g., TDLAS – Tunable Diode Laser Absorption Spectroscopy) precisely matched to gas absorption peaks, detecting concentrations via spectral analysis. Advantages: High selectivity and sensitivity, capable of detecting gases at ppb levels; Highly resistant to interference, unaffected by background gases; Suitable for long-range, online real-time monitoring. Disadvantages: Expensive, with high technical barriers; Bulky design with high power consumption; Complex maintenance, suited for specialised fields. Applications: Remote atmospheric pollution monitoring, online industrial pipeline...

What Are the Different Types of Gas Sensors? (Part 1)

17th Dec 2025

 GAS SENSORS, as we commonly refer to them, constitute a broad category that can be further subdivided into eight types based on their working principles. Users must understand the advantages and characteristics of each type to select correctly in specific application scenarios. 1. Electrochemical Gas Sensors Working Principle: Gases undergo oxidation/reduction reactions with the sensor electrode surface, generating current or potential changes proportional to gas concentration. Advantages: 1) Exceptionally high sensitivity, capable of detecting low-concentration gases at ppm or even ppb levels (e.g., toxic and hazardous gases); 2) High selectivity, enabling targeted detection of specific gases (e.g., CO, SO₂, NOₓ); 3) Low power consumption and compact size, suitable for portable devices and IoT modules. Limitations: 1) Electrolytes are susceptible to temperature and humidity, resulting in poor long-term stability; 2) Limited lifespan (typically 1–3 years), requiring periodic calibration; 3) Poor tolerance to high concentrations of corrosive gases, prone to electrode damage. Typical Applications: Industrial toxic gas detection, IAQ monitoring (formaldehyde), automotive exhaust emissions testing. 2. Catalytic Combustion Gas Sensor Working Principle: Combustible gases combust upon the surface of the sensor’s catalytic element, releasing heat that alters the element’s resistance. Gas concentration is calculated based on this resistance value. Advantages: 1) Rapid...
