What gases can YOURUIAN gas detectors measure?

Coverage of 600+ detection factors including H₂S / CO / CH₄ / O₂ / NH₃ / Cl₂ / SO₂ / NO₂ / VOCs / SF₆ / SiH₄ — common and specialty gases — supporting electrochemical, catalytic combustion, infrared, PID, thermal conductivity, and laser TDLAS sensing principles.

Are the products explosion-proof certified?

All fixed / portable / pump-aspirated core models pass Ex d ⅡC T6 Gb flameproof + Ex ia ⅡC T4 Ga intrinsic safety dual certification, with Explosion-Proof Certificates issued by the National Explosion-Proof Center, suitable for Zone 1/2 hazardous areas in petrochemical, gas, and coal mining sectors.

Can sensors and ranges be customized?

Yes. Customization is supported across gas type, range, enclosure material (aluminum / 304 / 316L stainless steel), communication interface (4-20mA / RS485 / Modbus / HART / LoRa / NB-IoT / 4G), alarm thresholds, and brand OEM. Standard products ship in 7 days; custom orders in 15–30 days.

What is the warranty period? How fast is on-site response?

12-month whole-unit warranty (sensor warranty calculated separately). Failure response within 24 hours; field engineer arrival within 48 hours. Paid extended warranty, maintenance contracts, and factory annual calibration (with certificate) available as long-term services.

Can the products integrate with existing DCS / SCADA / industrial IoT platforms?

Yes. All products come standard with 4-20mA + RS485 (Modbus RTU) + HART protocols, with optional LoRa / NB-IoT / 4G. The YOURUIAN proprietary IoT monitoring cloud platform also provides RESTful API + Webhooks for integration with EHS / MES / SCADA / industrial IoT platforms.

氢气 Detection

Formula H₂ · CAS 1333-74-0 · 极易燃 / 极宽爆炸范围

Hazard Level 高（火灾爆炸）

Molecular Weight 2.02

Explosive Limits 4% ~ 75%

⚠️ Hazards & Toxic Symptoms

Hydrogen is a colorless, odorless, and non-toxic gas, but it is extremely flammable, with an explosion range of 4-75% (one of the widest gases). The ignition energy is extremely low (0.02 mJ). It is lighter than air and accumulates at the top due to upward diffusion.

🏭 Typical Application Scenarios

Hydrogen energy/fuel cell
Petrochemical (hydrogenation refining)
Semiconductor (CVD)
Glass/Electronic Grade Gas
Aerospace

🔬 Detection Principle / Recommended Sensors

Catalytic combustion (most common) / thermal conductivity (ultra-high concentration) / semiconductor-specific H₂

Common Range：0-100% LEL / 0-100% Vol
