ZX-MK3-H2S

Overview:
The ZX-MK3-H2S is an integrated digital gas detection module designed based on the principles of electrochemical sensing. The module features an original factory-installed electrochemical hydrogen sulfide sensing chip, signal conditioning circuitry, temperature compensation algorithms, and a single-chip microcomputer data processing unit. It can directly output standard digital signals, eliminating the need for additional external amplification and filtering circuits. The product boasts high detection accuracy, excellent gas selectivity, and stable long-term operation performance, making it widely used in fixed gas detection instruments, environmental air monitoring systems, municipal pipeline and sewer monitoring equipment, toxic gas warning devices in petrochemical plants, and gas emission monitoring equipment for livestock and poultry farming.
