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.

二硝基苯 Detection

Formula C₆H₄N₂O₄ · CAS 99-65-0 · 芳香烃 / 苯系物

Hazard Level Medium

Molecular Weight 168.11

⚠️ Hazards & Toxic Symptoms

Dinitrobenzene belongs to the aromatic hydrocarbons/benzene series (containing a benzene ring structure), mostly as colorless flammable liquids with a distinctive aromatic odor. It is commonly associated with neurotoxicity - long-term exposure can damage the nervous system, liver, kidneys, and hematopoietic system. Some benzene derivatives (benzene, ethylbenzene, aniline) have been classified as carcinogens by the International Agency for Research on Cancer (IARC) and can induce leukemia. Commonly monitored using PID (IP 8.8 eV, high sensitivity).

📋 General Reference Information below is compiled from this factor's chemical category (芳香烃 / 苯系物). For specific exposure limits, monitoring plans, and sensor selection, please confirm with our engineers.
