FT - FHQ2: A High - Performance Four - Gas Detector for Industrial Applications

The FT-FHQ2 type Portable gas detector is a pump-suction four-in-one gas detector that can simultaneously detect four kinds of gases: combustible gas (EX), hydrogen sulfide (H₂S), carbon monoxide (CO), and oxygen (O₂).

Working Principle

Its sensitive components adopt high-quality gas sensors. It actively extracts the gas samples to be tested for analysis through the pump-suction method, converts the gas concentration into an electrical signal, and displays the real-time data and status on the LCD screen after data processing. When the gas concentration reaches or exceeds the preset alarm value, it will immediately give out audible, visual, and vibration alarm indications.

Advantage 1: Precision and High Efficiency

It uses high-quality gas sensors, which have high sensitivity and excellent repeatability. It can quickly and accurately detect gas leakage or situations where the gas concentration exceeds the standard. The response time T < 45s, effectively avoiding the interference of external environmental factors and ensuring the accuracy and reliability of the detection data.

Advantage 2: Easy Operation

It has a user-friendly design and is simple and quick to operate. It supports operation menus in both Chinese and English, allowing you to query historical alarm information at any time. It can also calibrate the gas alarm points according to the actual situation to meet the needs of various working conditions.

Advantage 3: Durability and Reliability

The sensors have a long lifespan. The lifespan of the EX, H₂S, and CO sensors is 2-3 years, and the lifespan of the O₂ sensor is 5 years. The whole device is made of a sturdy shell and has an IP65 protection level, with good dustproof and waterproof performance and strong anti-electromagnetic interference ability, enabling it to work stably in harsh industrial environments.

Advantage 4: Long-lasting Battery Life

It is equipped with a 4000mAh lithium battery. Under standard conditions, the standby time can reach 10-12 hours, and the charging time is only 2h-3h. It also supports USB charging, providing a strong guarantee for long-term on-site monitoring.

It is widely applicable to various industrial sites, such as the petroleum, chemical, metallurgical, power, mining, and other industries.
