✅Accurate and Reliable Nitrogen Detection
The BT-5800G nitrogen gas detector delivers precise readings from 0 to 100 PPM with a resolution of 0.1 PPM, ensuring highly accurate monitoring for enhanced safety in various environments.
✅ Fast Response and Clear Alerts
Equipped with an electrochemical sensor, it offers a T90 response time of ≤120 seconds. Dual-level audio-visual alarms promptly notify users when gas concentration exceeds preset limits.
✅ Rechargeable & Long-Lasting Battery
Powered by a built-in lithium battery, the detector supports continuous operation and is ideal for both indoor and outdoor use. The battery indicator reminds users to recharge in time.
✅ Multi-Functional Display
The clear LCD screen simultaneously shows nitrogen concentration (PPM), temperature (°C/°F), and humidity, providing comprehensive environment data at a glance.
✅ User-Friendly and Portable Design
Compact, lightweight, and easy to operate with one-hand controls. Features an auto power-off function and comes with a protective cap for probe storage.

✨ Why BTMETER BT-5800G Stands Out?
Ultra-Fast & Reliable Detection
→ Electrochemical sensor ensures <120s response time, critical for early leak detection.
Dual Alarms for Enhanced Safety
→ Customize AL1 (mild) and AL2 (severe) alerts to match OSHA/NIOSH safety thresholds.
Long-Lasting & Cost-Efficient
→ 2-year sensor life + rechargeable battery = 50% lower maintenance cost vs. competitors.
All-Weather Durability
→ Works flawlessly in extreme cold (-20°C) or humid environments (e.g., barns, labs).
User-Friendly Design
→ One-touch buttons, Celsius/Fahrenheit toggle, and clear LCD for effortless operation.
🏭 Who Needs This Detector?
Farmers & Livestock Managers: Monitor NH₃ levels in poultry houses or barns to protect animals and workers.
Industrial Workers: Detect leaks in chemical plants, refrigeration units, or fertilizer production.
Lab Technicians: Ensure safe ammonia levels during experiments or pharmaceutical processes.
Environmental Inspectors: Assess air quality in wastewater treatment facilities or hazardous zones.
🔧 Real-World Scenarios
Prevent Respiratory Risks: Instantly alerts when NH₃ exceeds 20ppm (OSHA’s permissible exposure limit).
Avoid Equipment Corrosion: Early detection prevents ammonia-induced damage to machinery.
Emergency Readiness: Rapid AL2 alarm triggers evacuation if levels hit 100ppm (severe hazard).
