The fixed gas detector consists of an alarm controller and a detector. The controller can be placed in the duty room and mainly controls the monitoring points. The gas detector is installed in the place where the gas is most likely to leak. The core component is a built-in gas sensor. The sensor detects the […]

Pumped Oxygen Analyzer
Pumping type gas analyzer is an intelligent high-performance analysis and detection instrument that can continuously monitor the measured gas and has the function of personnel fall alarm. The optional wireless function of the instrument allows security personnel to obtain the instrument data and alarm status in real time from anywhere. Intuitive data display, large 3.2-inch […]
Principle of Infrared Gas Analyzer
The principle of infrared gas analyzer is to use infrared to analyze the body. It is based on the difference in the concentration of the components to be analyzed and the absorbed radiant energy. The remaining radiant energy makes the temperature rise in the detector different, and the pressure on the two sides of the […]
Points to Know When Using an Ammonia Gas Detector
According to the national standard “Occupational Exposure Limits for Harmful Factors in the Workplace GBZ2-2002”, the maximum allowable ammonia concentration in the workshop is 30mg / M3, which is about 39.5ppm. In the actual application of ammonia detector, the following values are usually referred to: Average threshold (TLV-TWA): 25 (generally set as a first-level alarm […]

Integrated design reduces the influence of external interference on measured values; The probe uses special materials to make it more resistant to corrosion; Instrument housing with high protection level; Built-in display and button design, can ensure the service life of the instrument part even in harsh environments; Standard DN65 flange mounting makes installation simple and […]
Overview of Thermal Conductive Gas Analyzers
Thermal conductivity gas analyzer is a physical gas analysis instrument. Based on the principle that different gases have different heat conduction capabilities, it can estimate the content of certain components by measuring the thermal conductivity of the mixed gas. This kind of analytical instrument is simple and reliable, and it can be used for many kinds […]
Method for Detecting Carbon Dioxide in Air
Carbon dioxide has long been recognized as a colorless, odorless gas. It is heavier than air and its gas density is 1.9659 / L under standard conditions. Carbon dioxide in the atmosphere comes from: fuel combustion, such as boilers, civilian furnaces and other coal, oil, wood fired when burning carbon dioxide; engine exhaust contains high […]
How to Choose the Bus System and Branch Line System of Gas Detection System
For stationary gas detectors, the system configuration of on-site gas detection + controller centralized display interlocking is essential. For the two different wiring methods, they are commonly used in the bus system and branch line system, how to choose? This time Van Andy analyzes the advantages and disadvantages of the two for customers to refer to […]
