Overview
The H₂S Transmitter is a professional-grade gas detection solution engineered for precise and reliable monitoring of hydrogen sulfide in industrial environments. Offering a measurement range of 0–100 ppm with a high accuracy of ±3% FS and resolution of 1 ppm, it ensures consistent performance for critical safety applications.Designed for seamless integration, the transmitter supports multiple output options (RS485, 4-20mA, 0-5V, 0-10V), making it compatible with a wide range of control and monitoring systems. With low power consumption, a rapid response time of ≤35 seconds, and excellent stability (≤2% signal drift per month), it is optimized for continuous operation in demanding environments.Built to withstand harsh conditions, the device operates within a temperature range of -20°C to 50°C, humidity tolerance of 15–90% RH (non-condensing), and a pressure range of 90–110 kPa. Its long service life (≥24 months) and modular design further enhance reliability and ease of maintenance.Compact, durable, and highly efficient, this H₂S transmitter is ideally suited for use in oil and gas, chemical processing, wastewater treatment, and other high-risk industrial sectors where safety and accuracy are paramount.
