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.

FIX800 ETO (Ethylene Oxide) Gas Detector Installation — Hospital Sterilization Room

Project Details

This installation was carried out at a hospital ETO (ethylene oxide) sterilization room.

Endoscopes and other reusable medical instruments that come into direct contact with patients must be sterilized after each use. These instruments are sterilized daily in an ETO sterilizer. The issue is that ETO (ethylene oxide) — the gas used in these sterilizers — is highly toxic.

In South Korea, ETO (ethylene oxide) is classified as a hazardous substance. The occupational exposure limit for workers is set at 1 ppm. 1 ppm is equivalent to a concentration of 0.0001%. The fact that the exposure limit is set at such a trace level clearly demonstrates how hazardous this gas is — no further explanation is needed.

When fitted with an ETO sensor, the FIX800 fixed gas detector measures ETO concentrations in the range of 0 to 100 ppm. The alarm concentration threshold can be freely configured by the user. For example, when the alarm is set to 1 ppm, triggering that threshold activates the integrated beacon with a 90 dB audible alarm and visual strobe.

Hospital ETO sterilization rooms are typically very small — often only 3 to 7 m² in size. While awareness of ETO toxicity has grown and most rooms are now equipped with ventilation systems, small amounts of gas can still leak during sterilizer operation when gas valves or the unit door are opened. If the ventilation system malfunctions or has insufficient capacity, the toxic ETO gas can accumulate and directly harm hospital workers.
