The Yaoan BTQ-YA-CDX4 Portable Four in One Gas Detector is designed for personal and industrial gas safety monitoring, allowing users to detect four gases at the same time. The configuration shown monitors carbon monoxide CO, oxygen O2, hydrogen sulfide H2S and combustible gas such as natural gas or LEL.
The detector features a 1.77 inch TFT LCD display that shows real-time gas concentrations, time and battery status. It uses audible, visual and vibration alarms to provide clear warning when dangerous gas levels are detected. Yaoan also specifies high and low alarms, fault indication and three-colour status indicators for quick identification of operating conditions.
A built-in 3000 mAh rechargeable battery provides portable operation for industrial workers. The supplied product sheet states continuous operation of up to 12 hours, while Yaoan's current listing specifies at least 10 working hours, with charging completed in up to four hours.
The BTQ-YA-CDX4 also includes data logging capabilities for alarm, switching and fault records. According to the supplied product information, it can store up to 1,000 records, helping users review past events and support safety documentation.
With diffusion-type detection, physical control buttons and calibration functions, the unit is suitable for chemical plants, petroleum facilities, gas stations, metallurgy, gas distribution, painting operations and other environments where toxic or combustible gas leaks may occur.
