Explosion - proof Laser Gas Analyzer KGD - MQ - 509 for Industrial Site Production
Product Introduction
The Explosion - proof Laser Gas Analyzer KGD - MQ - 509 adopts Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology and can simultaneously measure the volume concentrations of gases such as O₂, CO, CO₂, H₂S, and CH₄ on - line. The instrument is equipped with pre - treatment components and is suitable for harsh working conditions such as those with moisture and dust. Its explosion - proof design can meet the gas monitoring needs of flammable and explosive places in multiple fields, ensuring the safety of the production process in industrial sites.

| Notes: ① All data in the table are measured under standard atmospheric pressure. ② The standard gas for measurement is provided by a unit certified by the national metrology department. All gases are diluted in dry nitrogen; the accuracy requirement for nitrogen is greater than 99.999%. ③ The reference response time is tested at a flow rate of 2L/min. ④ The optimal flow rate is 0.7 - 1.2L/min, and the actual application can reach up to 2L/min. | |||
