What does WANDI Korea do?

WANDI Korea is the official Korean distributor of WANDI environmental and gas measurement instruments, operated by RS Korea Co., Ltd. We provide sales, calibration, repair, installation, and technical support for portable and fixed multi-gas detectors and air quality monitoring systems, exporting to more than 20 countries with over 5,000 delivery records.

What products do you offer?

We supply portable multi-gas detectors (EDW100, EDW500, Gas Tiger series), fixed multi-gas detectors (FIX800, FIX900, FIX-AP), air quality monitoring systems (FIX5000), and gas leak detectors (GLD series) for industrial safety and environmental measurement.

Which gases can be measured?

Our instruments measure oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), combustible gases (EX), carbon dioxide (CO2), ammonia (NH3), and volatile organic compounds (VOC), among other hazardous and combustible gases found on industrial sites.

Do you provide calibration and repair services?

Yes. Beyond product sales, WANDI Korea provides in-house and national certified calibration, repair, installation, and ongoing technical support. Calibration and repair requests can be submitted through the quote/calibration/repair pages on our website.

How can I get a quote for a gas detector?

You can request a quote directly through the quote page on our website or through a nearby dealer. Let us know your application and target gases, and we will recommend a suitable model.

In which fields are the products used?

They are used across a wide range of industrial sites including laboratories, factories and plants, hospitals, military facilities, livestock and wastewater treatment, and construction sites for worker safety and environmental monitoring.

GasTiger 2000 Cl₂/ClO₂ Gas Detector — Water Disinfection and Treatment Facility Safety (Seoul)

GasTiger 2000 — Cl₂ (Chlorine) Gas Measurement for Water Treatment and Disinfection Facilities

This article introduces the GasTiger 2000 configured for Cl₂ (chlorine) gas measurement, primarily supplied to water treatment and disinfection facilities.

What Is Chlorine (Cl₂)?

Chlorine (Cl₂) is both an acutely toxic substance and a strong oxidizer that intensifies fire behavior. It is widely used in semiconductor process chemistry and, most commonly, as a disinfectant in municipal drinking water treatment.

Gas measurement equipment is supplied to municipal water utilities and wastewater treatment facilities, enabling engineers to work safely in environments where chlorine exposure is a daily risk.

Occupational Exposure Limits — Cl₂ and ClO₂

Chlorine (Cl₂) and chlorine dioxide (ClO₂) are widely used in disinfection and sanitation processes. Both gases perform important antimicrobial functions — and both are among the most hazardous gases found in industrial workplaces.

Cl₂ (chlorine) — TWA: 1 ppm / STEL: 3 ppm
ClO₂ (chlorine dioxide) — TWA: 0.1 ppm / STEL: 0.3 ppm

Even below 5 ppm, both gases can cause serious harm to people and the surrounding environment. A low-range, high-resolution Cl₂ sensor is essential for reliable detection at these trace concentrations.

GasTiger 2000 — Alarm Performance

Detecting even the smallest Cl₂ leak before it reaches dangerous levels is critical. The GasTiger 2000's alarm system — over 95 dB audible plus vibration — ensures workers receive immediate warning even in noisy industrial environments.

GasTiger 2000 — Feature Checklist

① Korean-language UI
② Onboard data logging with chart review
③ Domestic after-sales service — typical turnaround within one week
④ Calibration certificate available (additional charge)
⑤ Up to 3 toxic gas sensors (configuration varies by gas combination)

Sensor selection must match the target gas precisely. Electrochemical sensors can exhibit cross-interference from other gases present in the environment — always consult a specialist before finalizing the sensor configuration for any application.

Frequently Asked Questions

Q1. Why is a Cl₂ detector required in water treatment facilities?

Chlorine is used throughout the water purification process for disinfection, but leaks during handling pose an immediate hazard to personnel. With a TWA of just 1 ppm, even low-level exposure causes mucous membrane irritation. Continuous monitoring is mandatory wherever chlorine is used or stored.

Q2. Is ClO₂ more hazardous than Cl₂?

By TWA limit, yes — ClO₂ has a TWA of 0.1 ppm versus 1 ppm for Cl₂, making it ten times more restrictive. This means ClO₂ exceeds regulatory limits at far lower concentrations. Both gases are acutely toxic, but ClO₂ requires even more sensitive, low-range detection.

Q3. Can the GasTiger 2000 measure Cl₂ and ClO₂ simultaneously?

Yes. The GasTiger 2000 supports up to 4 sensors, allowing Cl₂ and ClO₂ sensors to be installed together. However, because electrochemical sensors can cross-react with chemically similar gases, the specific sensor combination should be confirmed with a specialist before ordering.

Q4. What is cross-interference in electrochemical sensors?

Electrochemical (EC) sensors respond to the electrochemical properties of a gas, not just its identity. Gases with similar chemical characteristics can trigger a partial response — for example, a Cl₂ sensor may respond to ClO₂, or an H₂S sensor to SO₂. This can produce inaccurate readings. Knowing which gases are present at the site is essential for correct sensor selection.

Q5. How is the data logging and chart function used in practice?

The GasTiger 2000 records timestamped measurement data automatically. When connected to a PC, data can be reviewed as time-series charts — useful for identifying concentration patterns during specific work tasks, detecting intermittent leaks, and generating periodic environmental compliance reports.
