GasTiger 6000 Ambient NO/NO₂/SO₂ Multi-Gas Monitor Delivery (Seoul)

GasTiger 6000 — NO / NO₂ / SO₂ Ambient Air Quality Monitor (Seoul)

This article introduces the GasTiger 6000, a portable multi-gas analyzer for simultaneous measurement of NO (nitric oxide), NO₂ (nitrogen dioxide), and SO₂ (sulfur dioxide) in ambient air quality applications.

GasTiger 6000 — Up to Six Sensors in One Portable Unit

The GasTiger 6000 accepts up to six gas sensors simultaneously. This delivery was configured as follows:

• NO (nitric oxide): 0–20 ppm
• NO₂ (nitrogen dioxide): 0–100 ppm
• SO₂ (sulfur dioxide): 0–20 ppm

Configured with three sensors for ambient hazardous gas analysis, the GasTiger 6000 enables simultaneous measurement and data logging of nitrogen oxides (NOx) and sulfur oxides (SOx) — the species most strictly regulated under Korea's Clean Air Conservation Act.

Kit Contents

Standard kit includes: main unit, gas probe, urethane and silicone sampling hoses, charging cable, Korean user manual, factory calibration certificate.

Industrial Safety Monitoring — Alarm Function Essential

The same platform is used for industrial safety walk-downs, so audible and visual alarm capability is mandatory.

Despite its compact form factor, the six-slot chassis allows the instrument to be reconfigured for a wide range of toxic and hazardous gases as monitoring requirements change.

Electrochemical sensors can exhibit cross-sensitivity to chemically similar gases. Always consult a specialist before finalizing the sensor configuration to ensure measurement accuracy in your specific environment.

Frequently Asked Questions

Q1. Why are NO, NO₂, and SO₂ so strictly regulated in ambient air?

NO and NO₂ are combustion-derived nitrogen oxides (NOx) that contribute to photochemical smog and fine particulate formation. SO₂ is a sulfur oxide (SOx) that causes acid rain and respiratory irritation. All three are tightly regulated under Korea's Clean Air Conservation Act and are emitted by power plants, industrial boilers, incinerators, and vehicle exhausts.

Q2. What is the difference between GasTiger 6000 and GasTiger 2000?

The GasTiger 2000 supports up to 4 sensor slots; the GasTiger 6000 supports up to 6. Where more than four gases need to be monitored simultaneously — as in ambient NOx/SOx measurement — the GasTiger 6000 is the appropriate choice.

Q3. What are the occupational exposure limits for NO, NO₂, and SO₂?

Under Korea's OSHA: NO — TWA 25 ppm; NO₂ — TWA 3 ppm / STEL 5 ppm; SO₂ — TWA 2 ppm / STEL 5 ppm. The tight limits for NO₂ and SO₂ mean that even low-level exposure can cause respiratory harm, making low-range, high-resolution sensors essential for these gases.

Q4. What is cross-sensitivity and how should it be managed?

Electrochemical sensors respond to the electrochemical properties of a gas — meaning a sensor optimized for one gas may partially respond to a chemically similar one. For example, an NO sensor may respond to NO₂, or an SO₂ sensor to H₂S. A full inventory of gases present at the measurement site should be established before selecting sensor chemistry, and specialist advice should be sought to minimize cross-interference.

Q5. Beyond ambient air quality, in what industrial applications is the GasTiger 6000 used?

Common applications include stack emission monitoring at power plants, incinerators, and steel mills; air quality management in road tunnels and parking facilities; leak detection at chemical plants; and NOx/SOx safety monitoring in any workplace where combustion processes are present.
