【English Introduction】
The Z-400 Portable Chlorine Detector is a high-performance handheld device specifically developed for environmental safety monitoring. Ideal for industrial facilities, laboratory environments, and water supply/drainage systems, this equipment delivers precise chlorine concentration detection through its advanced sensing technology and intelligent operational design.

Equipped with a highly sensitive gas sensor, the device provides real-time monitoring within 0-20ppm detection range, achieving 0.1ppm resolution. Its optimized airflow structure ensures rapid response to gas concentration changes, while the dual-alarm system combining vibration and LED/audible alerts immediately activates when readings exceed preset thresholds, enabling prompt safety interventions.

Featuring an ergonomic anti-slip housing and 2.4-inch sunlight-readable display, the detector offers clear visibility in various lighting conditions. The IP65-rated enclosure provides reliable protection against dust and water ingress, complemented by replaceable filter components that ensure long-term stability in demanding environments. The integrated rechargeable battery supports 12 hours of continuous operation for extended monitoring tasks.

The intelligent data management system stores up to 800 measurement records, with USB connectivity enabling easy data transfer. Automatic calibration reminders help maintain detection accuracy over time. Suitable for chlorine risk areas including wastewater treatment plants, chemical processing units, and medical sterilization facilities, this device serves as an essential tool for occupational safety management.
