What gases does the multi gas detector 4 gas monitor?
The portable multi gas detector can simultaneously monitor LEL (combustible gas), O₂ (oxygen), CO (carbon monoxide), and H₂S (hydrogen sulfide). For OEM/ODM customization, additional gas types can be integrated based on client requirements. This flexibility makes it ideal for confined spaces, chemical plants, oil & gas facilities, and mining operations.
How fast does the multi gas detector respond to gas leaks?
The response time is industry-leading: LEL <30 seconds, O₂ <20 seconds, CO/H₂S <60 seconds. Its high-sensitivity sensors provide accurate readings with excellent repeatability, ensuring rapid alerts to protect personnel and assets. Multi-mode alarms include sound, light, vibration, and display notifications for immediate awareness.
Can the multi gas detector be customized for branding or technical requirements?
es, the multi gas detector 4 gas OEM/ODM version supports full customization:
-
Logo and color branding for corporate identity
-
Customizable alarm thresholds and sensor calibration
-
Optional connectivity modules (Bluetooth, GSM, wireless)
-
Explosion-proof or corrosion-resistant designs for harsh environments
This makes it perfect for B2B clients seeking tailored multi gas detectors for industrial safety.
What is the battery life and operating duration of the detector?
The portable multi gas detector is equipped with a rechargeable 2000mAh lithium battery, providing more than 8 hours of standby time. This ensures uninterrupted monitoring during long shifts or extended field operations, meeting industrial safety requirements efficiently.
How durable is the multi gas detector 4 gas in industrial environments?
The detector is designed with high-strength engineering plastic, providing impact resistance, waterproofing, dustproofing (IP65/IP66), and explosion-proof protection. Its compact size (130×65×45 mm) and lightweight design (280g) make it highly portable while maintaining robust performance in harsh industrial conditions.
How long do the sensors last, and how is maintenance handled?
The O₂ sensor lasts up to 5 years, while other sensors (LEL, CO, H₂S) typically last 2 years under normal usage. For OEM/ODM clients, pre-calibrated sensors and customizable maintenance schedules can be provided, reducing downtime and ensuring reliable, high-precision detection for industrial safety applications.
