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) Leak Detector Installation — Hospital and Medical Sterilizer Rooms (Nationwide)

FIX800 ETO (Ethylene Oxide) Leak Detector Installation — Hospital Sterilizer Rooms (Nationwide)

This article covers installation cases for the FIX800 ETO leak detector, widely used in hospital sterilizer rooms across the country.

What Is ETO (Ethylene Oxide)?

ETO (ethylene oxide), commonly referred to as "EO gas" or sterilization gas, is used primarily for sterilizing medical devices and instruments.

ETO is highly effective as a sterilant, but even a small leak is acutely harmful. It is classified as a hazardous substance under Korea's OSHA, with regulated occupational exposure limits.

Hospital Sterilizer Room — Sterilizer and Gas Cylinder

ETO sterilizer units with attached gas cylinders are found throughout hospitals. As the sterilizer operates using ETO from the cylinder, aging equipment or a loose valve can allow small amounts of gas to leak into the room.

FIX800 Installation Process

ETO detector installation is straightforward. The unit is secured to the wall using a power drill, then power is connected.

Once power is applied, the initial setup is essentially complete. Before finishing, correct power-on and zero calibration must be verified.

After confirming proper operation, the facility manager is briefed on the rationale for the mounting location and the confirmed operational status before final finishing work begins.

Once cable molding is complete, installation is finished. Total on-site time is typically around 30 minutes.

Ventilation Is Essential During Sterilizer Operation

ETO concentrations may rise during sterilizer operation cycles. Adequate ventilation in the sterilizer room is therefore mandatory — not optional.

Frequently Asked Questions

Q1. What are the occupational exposure limits for ETO?

Under Korea's OSHA: TWA 1 ppm and STEL 5 ppm. ETO is also classified as a carcinogen, meaning chronic low-level exposure carries long-term health risks even below the acute limits. Continuous monitoring in sterilizer rooms is strongly recommended.

Q2. Where should an ETO detector be installed?

ETO is approximately 1.5 times denser than air and tends to accumulate near floor level. Installation within 30 cm of the floor, near the sterilizer and gas cylinder valve connections, is generally recommended. Exact placement should be confirmed with a specialist based on the room layout.

Q3. Does the detector continue operating during sterilizer cycles?

Yes — continuous monitoring is the purpose. Small amounts of ETO may be detected during normal sterilizer operation, so alarm thresholds should be set appropriately to distinguish normal operation from a hazardous leak. Configuration should reflect the site's baseline ETO levels.

Q4. Is a detector alone sufficient without a ventilation system?

No. A detector identifies the presence of gas and triggers an alarm — it does not remove gas from the room. To protect personnel when an alarm occurs, ventilation must be available to exhaust the gas and enable safe evacuation. Detectors and ventilation systems are complementary and should always be deployed together.

Q5. Where else is ETO monitoring required beyond hospitals?

ETO is used in medical device manufacturing and sterilization facilities, food packaging sterilization plants, and spice and grain fumigation operations. All such facilities are required under Korea's OSHA to manage ETO exposure, making fixed detector installation the standard practice.
