Operating principle of portable H2S analyzer

The P1500 series is a portable H₂The S analyzer can provide a cost-effective analysis method for process control, air quality, and product quality control. In addition, the analyzer has the characteristics of independence, accuracy, and low maintenance. The instrument adopts dual microprocessor technology,Can provide H based on the principle of non-interference with lead acetate operation₂S continuous online analysis.Compact structure, weighing approximately 4.5Kg. Versatile functions,Wide range of measurement (ppb~500ppm),No need for dilution. Regarding H in the atmosphere and process flow₂Analyze S and adjust the flow rate with precise flow meters. Then, the sample gas is sent to a lead acetate induction band, which is provided with H through a photodiode detector and an LED light source emitting system₂Output ratio of S concentration. This signal is processed through an 18 bit analog-to-digital converter and relevant analysis software to generate a linear 4-20mA output (optional). LCD displays current readings, alarm status, program prompts, fault indications, and other information. The P1500 series is a field validated H₂The S analyzer can detect H in the sample gas₂S provides continuous quantitative monitoring with minimal maintenance.
