BH-4S 4 in 1 Combustible Gas Detector Oxygen O2 Carbon Monoxide Hydrogen Sulfide Toxic And Harmful Gas Concentration Detector Leak Detector

Descriptions:

•4 in 1 Gas Detector Oxygen O2 H2S Carbon Monoxide CO Flammable Gas Analyzer Monitor Toxic Gas and Harmful Gas Leak Detector
•It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers’ life and avoid damage on the relevant equipments. 

Features:

 

The product support four kinds of  gas detection: flammable gas (EX), oxygen (O2), hydrogen sulfide (H2S), carbon monoxide (CO)

 

1. Industrial-grade sensor, high precision, real data, strong stability, real-time detection, can view the historical alarm data, and has a data storage function

 

2. Four alarm mode (sound, light, vibration, display) is not easy to ignore, high security, high and low alarm value can be set free

 

3. High-strength ABS material, waterproof, dustproof, explosion-proof, three anti-design

 

4. Data connected to the computer, can store 500 sets of alarm records, with the software, you can query the alarm data, export, easy to compare the analysis of data changes

 

5. Simple operation, bilingual, three buttons, powerful, 2.4-inch LCD screen, resolution 320 * 240 HD interface display, clear and comfortable.

6.Chinese and English bilingual settings

7. Natural diffusion sampling method and high-sensitivity sensor, with high sensitivity and repeatability.

8.32-bit built-in MCU, high reliability and self-adaptation ability.

9.Compact design, easy carrying.
