CH Refrigerant CO₂ NH₃ Leak Detector - NDIR Sensor, 0.1ppm Sensitivity - KS-GB250
Designed for multi-gas leak detection, the KS-GB250 employs a non-dispersive infrared (NDIR) sensor, offering robust anti-interference capability for precise measurements of SF6, R22, R410, R600, CO₂, NH₃, and more. Its embedded computer system ensures stability, while the sensor’s automatic calibration function minimizes maintenance. The detector features intuitive touch control, digital direct reading, and alarm capabilities with sound and color-changing visual alerts.
Key Features
- Multi-Gas Compatibility:Supports 13+ refrigerants across four sensor types, ideal for diversified industrial applications.
- Intelligent System:Embedded computer with auto-calibration ensures long-term accuracy without manual adjustment.
- User-Friendly Interface:Touchscreen control, real-time flowmeter monitoring, and customizable alarm points for intuitive operation.
- Data Management:Stores measurement records with time stamps, enabling direct printing or USB export for report generation.
