LH200 Portable Combustible Gas Pipeline Detector

I. Instrument Overview:

The LH200 Portable Combustible Gas Leak Detector is designed for detecting alkane-based combustible gases. It can identify minor leaks in pipelines and valves.

II. Applicable Scope:

Suitable for gas company pipeline leak inspections, household gas detection by gas companies, factory pipeline safety inspections and maintenance, explosion-proof environments, and transportation inspection of repair items.

III. Instrument Features:

1. Equipped with a high-performance planar ceramic heater semiconductor sensor, offering better impact resistance.

2. Large-screen dot-matrix LCD display with dual numerical and curve display for intuitive and convenient operation.

3. Features automatic and manual zeroing design, effectively reducing the complexity of calibration.

4. Dual-range function capable of measuring PPM and LEL concentration levels of combustible gases, with automatic range switching.

5. Dual power management function: main power uses a high-capacity lithium battery, providing over 14 hours of operation; alkaline batteries can also be used.

6. Equipped with a mute function to effectively avoid concerns among sensitive individuals.

7. Features low battery warning and automatic shutdown function.

8. Shares a charger with mobile phones for convenience and efficiency.
