Test items and characteristics of portable gas detection equipment
The development of portable gas detection equipment can detect leaks early. Certain disasters are inevitable. How to effectively suppress, monitor and early warning, and how to use high-tech means to effectively control accidents and reduce casualties and property losses are practical problems that need to be resolved by key technologies for safe production. Through the study of the early physical and chemical properties of the accident, gas detection and monitoring can effectively carry out pre-disaster suppression, so that possible disasters can be controlled in advance, while protecting personal safety. The key to the transition from passive rescue technology to a new generation of active prevention technology is intelligent monitoring technology.
Jingxun Changtong portable gas detection equipment adopts the latest digital integrated circuit technology and international gas detection technology to design a new intelligent gas detection instrument. A large-size full-color LCD screen is used to display the readings in real time. For the probe, a well-known brand manufacturer in the industry is selected. Relying on several years of gas transmitter research and development experience, it uses a mature, stable and long-life probe solution.
The detector adopts the natural diffusion method to detect the gas, and the detection circuit designed by the digital chip of the international manufacturer can achieve very high sensitivity and excellent repeatability. The shell is made of industrial-specific high-strength composite plastic, which has high strength and good hand feeling, and has the functions of waterproof, dustproof and explosion-proof.
This detector is widely used in petrochemical, environmental protection, metallurgy, mining, agriculture, experiment, surveying and mapping industries.
Rich man-machine interface, full-color interface designed based on the latest embedded thinking, can query, record, and display gas data in real time.
Three kinds of gas concentration display modes, single gas number + meter display, multi-gas collective display, optional real-time curve display.
Optional data storage function, supports up to 100,000 data storage functions, can export data to a computer through Excel, and perform printing, editing, icon display functions, etc.
