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.

ETO (Ethylene Oxide) Gas Detector EDW500: Essential Safety Guide for Hospitals & Sterilization Facilities

Ethylene oxide (ETO) is essential for hospital sterilization but is an extremely toxic, carcinogenic gas dangerous even below 1 ppm. The WANDI EDW500, IECEx-certified for explosive atmospheres, simultaneously measures up to 5 gases including ETO, delivering instant alarms to protect workers.

What is ETO (Ethylene Oxide)? Why is it Dangerous?

Ethylene oxide (ETO, C₂H₄O) is a colorless, flammable, and highly toxic gas widely used in hospital sterilization, semiconductor manufacturing, food fumigation, and chemical synthesis. ETO is classified as a Group 1 carcinogen by IARC, with OSHA's permissible exposure limit (PEL) of just 1 ppm (TWA) — meaning even trace amounts pose serious health risks.

💡 Key Point

ETO is nearly odorless, making it impossible to detect by smell alone. A gas detector is not optional — it is mandatory for any ETO-handling environment.

Health Effects of ETO Exposure

Concentration	Duration	Health Impact
1 ppm	8 hrs (TWA)	OSHA PEL — long-term cancer risk (leukemia, lymphoma)
5 ppm	15 min (STEL)	Headache, dizziness, mucous membrane irritation
50 ppm	Minutes	Respiratory irritation, nausea, vomiting
200 ppm	Short-term	Severe respiratory distress, pulmonary edema risk
800+ ppm	Immediately	Loss of consciousness, death risk
