product description

Gas introduction:

Benzene is a kind of hydrocarbon which is the simplest aromatic hydrocarbon. It is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at normal temperature, and has a strong aromatic odor. It is hardly soluble in water, easily soluble in organic solvents, and itself can be used as an organic solvent. The ring system of benzene is called benzene ring. The structure of benzene ring after removing a hydrogen atom is called phenyl, which is represented by Ph. Therefore, the chemical formula of benzene can also be written as PhH. Benzene is a basic petrochemical raw material, and its output and production technology level are one of the signs of a country's petrochemical development level.

SK-600-C6H6 on-line benzene gas alarm can perform continuous online monitoring for 24 hours, on-site display of concentration and exceeding standard sound and light alarm, and remote data transmission. Adopt 2.5-inch high-definition color screen to display the concentration in real time. According to different detection gases, select the best brands of the current industry's electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoion principle gas sensors, Swiss high-precision capacitive digital temperature and humidity sensors SK-600-C6H6's advanced circuit design and mature kernel algorithm processing have obtained a number of software work patents and appearance patents, thus giving birth to the industry's leading new generation of multifunctional fixed online benzene gas detection alarms. SK-600-C6H6 can detect the gas concentration in the pipeline or confined space, the atmospheric environment can also detect the gas leakage, and can also detect the purity of high concentration single gas. The sturdy and durable explosion-proof shell and fluorocarbon paint surface treatment process are suitable for various hazardous locations and corrosive environments with strong acids and alkalis. They are resistant to wear and tear and will not fade or paint fall within 10 years.

Precautions:

The gas sensor module is designed with seven pins, which are installed on the sensor socket by plugging and unplugging. To ensure reliable connection, a dedicated jack should be selected. The jack should be arranged according to the corresponding pins, and the jack should be installed vertically and soldered firmly. According to the special requirements of users, it is not necessary to use the pin plug method, but the external lead method, the lead model is ZR-BVR0.75, the wire length generally does not exceed 150mm. In non-explosion-proof places, it can be hot plugged with electricity. For work sites where explosion protection is required, the power to the equipment connected to the sensor must be turned off before installation.
