GasTiger 2000 ambient monitor — O₃ and NO₂ — VPE Korea

Hello from VPE Korea. Today we introduce the GasTiger 2000 for ambient monitoring of O₃ (ozone) and NO₂ (nitrogen dioxide).

One GasTiger 2000 can host both NO₂ and O₃ sensors, but at the buyer’s request we supplied two separate instruments.

GasTiger 2000 — O₃ (ozone) span (refer to the product photo).

GasTiger 2000 — NO₂ span (refer to the product photo). Before detailing hardware, we explain why O₃ and NO₂ are monitored together.

Nationwide ozone conditions on the day of the visit: rain and weak UV kept levels generally favorable. Ozone forms through photochemical reactions, so sunny summer days often show higher ambient ozone. When ozone rises, people may notice odors, coughing, eye irritation, headaches, shortness of breath, or visual disturbance—so it is a parameter you must track.

How ozone forms in ambient air. Understanding the chemistry explains why NO₂ and O₃ are paired in monitoring programs. Ozone and nitrogen dioxide are classic secondary pollutants.

GasTiger 2000 is one of our flagship portables: flexible ranges and up to four simultaneous sensors make it ideal for field crews who need portable analysis.

Example occupational limits (reference): O₃ — STEL 0.2 ppm; TWA 0.08 ppm. NO₂ — STEL 5 ppm; TWA 3 ppm.

Because the client tests elevated concentrations, we configured relatively high spans while retaining 0.01 ppm-class resolution. ★ Selecting the correct model for your environment is essential for accuracy. ★ For multi-gas questions, contact us through the quick banner on the right.
