The explosion tester is an intrinsically safe instrument that can continuously detect toxic, hazardous, flammable and explosive gas concentrations in the operating environment. It is suitable for explosion-proof, toxic gas leakage rescue, underground pipelines or mines and other places, can effectively ensure the safety of life of workers is not infringed, and the production equipment is free from losses.
The explosion detector measures the gas concentration by means of natural diffusion, and adopts an imported electrochemical sensor (combustion gas is a catalytic combustion type), which has excellent sensitivity and excellent repeatability; the instrument adopts embedded micro-control technology, and the Chinese menu has a simple operation and complete functions. , High reliability, the overall performance of the domestic leading level.
The explosion tester shell is made of high-strength engineering materials and composite elastic rubber materials with high strength, good feel, and waterproof, dustproof and explosion-proof. It is suitable for detecting the concentration of carbon monoxide in the ambient air. It is widely used in metallurgy, power plants, chemical industry, mines, tunnels, tunnels, underground pipelines and other places to effectively prevent poisoning accidents.
Explosive meter features:
Imported sensors, stable and reliable performance, automatic calibration and zero-resolved large-screen LCD display Chinese operation interface battery power real-time display, undervoltage warning, low-voltage automatic shutdown with real-time clock function two-stage triple alarm (sound, light, vibration), not easy to ignore the boot Functional self-test, sensor, battery, circuit and alarm function 2000 data storage sensor fault detection alarm password management function, important operations require password verification, effectively prevent misoperation automatic calibration function, reduce the measurement error measurement instrument can be installed in a specific Specific gas leaks are detected at the detection point. The explosion tester is generally a two-body type. A sensor and a detection head consisting of a transmission are integrally installed at the inspection site, and a secondary meter composed of a circuit, a power supply, and a display alarm device is integrally installed in a safe place to facilitate monitoring. Its detection principle is the same as described in the previous section, but it is more suitable for the continuous and long-time stability required by the fixed test in terms of technology and technology. They also need to be selected according to the type and concentration of gas in the site, and they should also be careful to install them on the site where the specific gas is most likely to leak, for example, to select the most effective height of the sensor installation according to the specific gravity of the gas.
With the development of manufacturing technology, portable explosion testers are also a new choice for us. Since this type of instrument can be equipped with multiple gas (inorganic/organic) detection sensors on a host computer, it has the characteristics of small size, light weight, corresponding rapidity, and multiple gas concentration display at the same time.
It should be noted that when selecting this type of portable explode instrument, it is best to select an instrument with a separate switch for each sensor function to prevent the use of one sensor from affecting other sensors. At the same time, in order to avoid clogging of the suction pump due to water ingress, it is also safer to select a smart pump design with a pump stop alarm.
Attention to the Use of Portable Explosive Meters 1. Pay attention to regular calibration and testing. The portable explosion tester is also similar to other analysis and detection instruments, and is measured by using a comparative method. During the measurement, the instrument compares the electrical signal generated by the gas concentration to be measured with the standard concentration of the electrical signal, and the calculation is accurate. Gas concentration value. Therefore, zero calibration of the instrument at any time, and regular calibration of the instrument is an indispensable task to ensure accurate measurement of the instrument. It should be noted that at present, many explosion testers can replace the detection sensors. However, this does not mean that one detector can be equipped with different detector probes at any time. Whenever a probe is replaced, the instrument must be recalibrated in addition to a certain sensor activation time. In addition, it is recommended to respond to the standard gas of the instrument before using it to ensure that the instrument really protects the instrument.
