GasTiger 2000 Portable Gas Detector — ClO₂ (Chlorine Dioxide) Measurement Application (Seoul Yeongdeungpo)

Wandi GasTiger 2000 Portable Gas Detector — ClO₂ Measurement Application

Gas accidents remain a serious hazard in industrial workplaces. They typically occur when workers in enclosed spaces are exposed to a specific gas for an extended period, preventing adequate oxygen supply to the body — with outcomes ranging from acute illness to fatalities. Staying properly equipped for prevention is essential.

This article introduces the Wandi GasTiger 2000 portable gas detector.

ClO₂ (Chlorine Dioxide) Measurement Application

This case involves ClO₂ (chlorine dioxide) concentration measurement. ClO₂ is used as a disinfectant, bleach, and biocide, and is considered relatively low risk at trace levels. Because it works through oxidation rather than chlorine substitution, it produces fewer disinfection by-products than conventional chlorine-based products.

However, at elevated concentrations, the risk profile changes significantly. ClO₂ is used in drinking water treatment at approximately 1 ppm (0.0001%). Ambient air exposure at around 45 ppm causes strong irritation to the eyes and nasal passages; above approximately 350 ppm, exposure can be life-threatening.

GasTiger 2000 — Product Features

The GasTiger 2000 detects and measures gases in ambient air, protecting users from hazardous exposure. In emergency situations, it provides rapid concentration readings for faster risk assessment.

• High repeatability for reliable routine measurements, with accuracy sufficient for regulatory compliance and process control
• Onboard data logging for recorded measurement histories
• Configurable with 1 to 4 sensors depending on the gases required at the site

The built-in pump actively draws sample gas for fast detection. The pump can be switched on or off as needed — active for rapid response, passive diffusion mode for extended battery life in continuous monitoring applications.

The GasTiger 2000 supports per-sensor alarm setpoints and provides three alarm channels — audible, vibration, and LED — ensuring alerts are perceived even in loud or physically demanding work environments.

Frequently Asked Questions

Q1. Isn't chlorine dioxide (ClO₂) considered safe for humans?

At trace concentrations (around 1 ppm) used in water treatment or food sanitation, ClO₂ poses minimal risk. However, ambient air exposure at 45 ppm causes strong mucosal irritation, and above 350 ppm it can be life-threatening. In production environments where concentrated ClO₂ is handled, gas detection is mandatory.

Q2. What gases can the GasTiger 2000 measure?

The GasTiger 2000 supports a wide range of sensor options including ClO₂, O₂, CO, H₂S, LEL, CO₂, and others. Up to four sensors can be installed simultaneously, allowing 1 to 4 gases to be monitored in a single instrument depending on site requirements.

Q3. How is the data logging function used?

Readings are automatically stored in onboard memory during measurement. Data can be downloaded to a PC and analyzed as time-series charts. Logged records support workplace monitoring documentation, regulatory reporting, and trend analysis.

Q4. Why are all three alarm modes — sound, vibration, and LED — needed?

Industrial environments often involve high ambient noise, and workers may be wearing thick gloves or hearing protection. Relying on sound alone can lead to missed alarms. Combined audible, vibration, and visual signaling ensures the alarm is perceived regardless of the working conditions.

Q5. When would the pump be switched off?

Switching to diffusion mode reduces battery consumption and eliminates pump noise — useful in quiet environments such as laboratories or during extended continuous monitoring sessions where battery life is a priority. For rapid detection in hazardous areas, the pump is activated for active sampling.
