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.

Dry-Ice Cold Storage CO2 Measurement — GasTiger 2000 Portable Gas Detector in Incheon

Dry Ice and CO2 (Carbon Dioxide)

Dry ice — familiar from ice-cream shops — is carbon dioxide (CO2) brought to a solid state under high pressure and low temperature. The cold storage facility in this case also relies heavily on dry ice.

CO2 Build-up Risk in Cold Storage

In large cold-storage rooms, evaporating dry ice can raise CO2 concentration, creating a risk of safety incidents. Measurement-based management is therefore necessary.

On-Site Test

We carried out a test by entering the site directly. Within about 10 seconds, the lack of oxygen was physically noticeable: the high CO2 concentration made breathing difficult and caused dizziness.

Because of the safety risk, the instrument was left in place and we exited the room immediately (filmed with the site manager's permission).

★ Key point ★
Whether the detector can measure stably even at low temperatures around −20 °C.

As shown, within a few minutes CO2 rose to nearly 10% vol (100,000 ppm). At this level, exposure can lead to vomiting, fainting, and potentially death.

As the chart indicates, many safety incidents are caused by CO2, so we hope on-site workers always operate in safe spaces and conditions.

GasTiger 2000 Low-Temperature, High-CO2 Measurement

The GasTiger 2000 we supply can measure high concentrations of CO2 stably even in low-temperature environments.

Frequently Asked Questions (FAQ)

Q1. Why does CO2 concentration rise in cold-storage rooms?

Dry ice (solid CO2) is widely used in cold storage, and as it evaporates the carbon dioxide concentration increases.

Q2. How dangerous is a high CO2 concentration?

During the on-site test, CO2 rose to nearly 10% vol (100,000 ppm) within minutes — a level that can cause vomiting, fainting, and potentially death.

Q3. Can it measure in sub-zero cold-storage environments?

Yes. The GasTiger 2000 can measure high concentrations of CO2 stably even at low temperatures around −20 °C (operating temperature −20 to 55 °C).

Q4. Can the GasTiger 2000 measure gases other than CO2?

Yes. As a portable multi-gas detector, it can be configured with sensors for up to seven gases.
