Standard gas refers to "reference gas" with accurate quantitative values for instrument calibration. It is formulated by precisely blending pure gases and diluents, and its quantitative values are traceable to national metrological standards. Its core value lies in "unifying testing benchmarks", widely applied in environmental monitoring, industrial quality inspection, and medical equipment calibration.

Standard gas refers to "reference gas" with accurate quantitative values for instrument calibration. It is formulated by precisely blending pure gases and diluents, and its quantitative values are traceable to national metrological standards. Its core value lies in "unifying testing benchmarks", widely applied in environmental monitoring, industrial quality inspection, and medical equipment calibration. It directly determines the accuracy and compliance of testing data, serving as a key guarantee for reliable production and detection.

I. Core Applications: Calibration Demands in Three Key Fields

Environmental Monitoring: Sulfur dioxide (SO₂) and nitrogen oxide (NOₓ) standard gases in nitrogen (concentration: 50-1000ppm) are used to calibrate Continuous Emission Monitoring Systems (CEMS). This ensures authentic pollutant emission data from power plants and chemical enterprises, complying with GB 13223 Environmental Standards. Dissolved oxygen standard gas is applied in water quality testing to guarantee the accuracy of COD and ammonia nitrogen detection.

Industrial Quality Inspection: Carbon dioxide-nitrogen mixed standard gas (ratio: 0-100%) is used in food packaging testing to calibrate gas analyzers and check packaging tightness. Propane standard gas (concentration: 1000ppm) calibrates automobile exhaust analyzers, ensuring accurate data for vehicle annual inspections.

Medical & Scientific Research: Medical oxygen concentration standard gas (oxygen content: 21%-100%) calibrates ventilators and oximeters to ensure medical safety. Methane-air standard gas is utilized in scientific experiments to calibrate gas chromatographs, ensuring reproducible experimental data.

II. Core Values: Accurate Quantification, Error Control & Efficiency Enhancement

1. Metrological Traceability: Certified by national metrology, with an error of ≤±1%. After calibration, the instrument testing error is reduced by over 30%. 2. Scenario Adaptability: Customizable concentration (ppm to percentage level) and components (binary to multi-component mixtures) to meet diverse instrument requirements. 3. Compliance Guarantee: Standard gases for environmental and industrial testing provide metrological certificates, helping enterprises pass regulatory inspections.

III. Safety & Selection: 3 Steps to Choose the Right "Calibration Ruler"

Safety Notes: Store away from fire sources and direct sunlight; secure cylinders to prevent tipping. Open valves slowly during operation to avoid gas impact; wear gas masks when handling toxic standard gases (e.g., hydrogen sulfide).

Selection Logic: 1. Clarify usage (e.g., waste gas type for environmental protection, oxygen concentration type for medical care). 2. Confirm parameters (concentration range, components, accuracy class). 3. Choose suppliers with metrological certification, calibration certificates, and 24/7 after-sales support.

The core of standard gas lies in "reliable quantification". Selecting the right product and service can avoid distorted testing data and compliance risks. For custom industrial/environmental standard gas or calibration solutions, feel free to contact us.
