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.

Confined Space Definition, Hazards & Safe Work Procedures

Confined Space Definition, Hazards & Safe Work Procedures | Gas Detector EDW500

A confined space is defined not by its structure but by its hazards — oxygen deficiency, toxic gases, fire, or explosion risk. Over 2015–2024, 298 workers were injured and 126 died (42.3% fatality rate) in confined space accidents in Korea. Pre-entry gas measurement and strict safety procedures are now legally mandated.

💡 3 Key Points

A confined space is defined by hazard, not structure.
The fatality rate in confined space accidents was 42.3% over 2015–2024.
Korean regulations now mandate gas detector provision and 3-year data record retention.

What Is a Confined Space? Legal Definition

Under Korea's Occupational Safety and Health Standards Rules, a confined space is any location where risks of asphyxiation, fire, or explosion due to oxygen deficiency or hazardous gases exist — regardless of physical enclosure.

Acceptable Air Quality Standards

Gas	Acceptable Range
O2 (Oxygen)	18% ≤ O2 < 23.5%
CO2 (Carbon Dioxide)	Below 1.5%
CO (Carbon Monoxide)	Below 30 ppm
H2S (Hydrogen Sulfide)	Below 10 ppm
Flammable Gas (EX)	LEL 10% or below

Recommended Gas Detector: EDW500

Simultaneous measurement of 5 gases: O2, CO, H2S, CO2, LEL
Built-in SIM — no separate Wi-Fi needed. SIM/data/cloud fees all free.
Auto-saves every 1 minute (adjustable 1 min to 1 hour); Excel/PDF export + auto email reporting
Real-time alarm to PC/smartphone on threshold exceedance
In-house calibration and A/S; within 5 business days after receipt
Applicable to manholes, septic tanks, water tanks, storage tanks, etc.; compatible with pump for pre-entry measurement

⚠️ Data Retention Notice

DCMS cloud storage retains data for 3 months. However, the automatic email reporting service sends measurement data to the registered administrator email every 3 months, so simply keeping those emails is sufficient to meet the legal 3-year data retention requirement — no manual download needed.
