High performance portable gas detector has humanized operation functions such as one-key security detection, one-key storage, automatic image flipping, as well as the man down alarm function. The compact design makes it easy carrying.
Functions
- The portable gas detector can effectively resist a three-meter drop, has passed the EMC anti-static interference test and can work normally in the walkie-talkie environment.
- Password protection function prevents non-operators from modifying menu parameters. With safety reminder function, sound and light vibration alarm function, let operators work without worries. The high and low alarm latched function allows the operator to better capture the sudden change of the gas concentration value.
- Real-time value, TWA, STEL, MAX, MIN multiple numerical display, and the screen can be automatically turned 180 degrees, which is convenient for viewing in special operating environments.
- Built-in powerful sampling pump, fast detection speed. It can be connected 20m sampling tube externally, which is convenient for long-distance or confined space detection.
- Pump suction and diffusion dual use, to provide operators with more reliable protection. With a water trap filter, it can effectively filter water, oil, dust and other impurities. It can also be used in harsh industrial environments such as coal mines and petroleum fields.
- Beautiful and friendly user interface, reasonable and easy-to-use interactive mode. Standard storage function, one-click data export, convenient for users to analyze.
- Unique modifiable ID identification function, convenient for users to allocate and manage the instrument. A full range of automatic detection functions, automatic prompts for voltage, pump failure alarms, etc., more comfortable to use.
- One-key open storage, automatic image flip. It supports each channel sensor to restore the factory setting separately and multi-language including English, Chinese and etc.

Tips: What is portable explosion-proof gas detector?
Portable gas detectors can be used for harmful gas detection, organic VOC gas detection, combustible gas detection and single gas detection. Its development direction is miniaturization and automation, in order to achieve long-term monitoring. The development of portable gas detectors allows the leakage process to be discovered at an early stage. The occurrence of certain disasters is inevitable. How to effectively restrain, monitor and early-warning, and how to reasonably use high-tech means to effectively control accidents and reduce casualties and property losses in response to accidents that have occurred are practical problems that need to be addressed in key production safety technologies. Through the study of the physical and chemical properties in the early stage 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 and control technology is intelligent monitoring technology as the core.
Portable gas detectors are widely used in industrial safety monitoring, indoor air quality testing, hazardous substance testing, and environmental protection monitoring. Aiming at the key links in the process of disaster incubation, occurrence, and development, disrupting the chain development chain is an important link in the safety accident prevention and control technology system.
The portable gas detector can be divided into diffusion type and pump suction type according to its sampling principle. The so-called diffusion type is to place the probe in the dangerous zone of detecting gas, the gas to be measured is diffused into the probe from the space, and the alarm is placed in the monitoring room for instructions and alarms. The pumping type is to suck the gas to be measured into the detection probe. The suction pump and the built-in gas detector are set together. The detector is set in the dangerous place of the gas to be measured to detect the execution instructions and alarm functions.
