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.

Intercity Bus Terminal Reservoir Tank O₂/H₂S Two-Gas Detection and Monitoring (Busan)

Project Details

Why Reservoir Tank Safety Management Matters

Intercity bus terminals are public facilities with many operating systems, and safety management of unseen spaces is just as essential
Reservoir tanks, sumps, and water tanks carry a risk of oxygen deficiency and hydrogen sulfide buildup when ventilation is inadequate
Confined-space standard: oxygen must be maintained at 18–23.5%, hydrogen sulfide below 10 ppm

Oxygen Deficiency Risk

Oxygen can be consumed inside an enclosed reservoir tank
Symptoms: dizziness, headache → loss of consciousness → death by asphyxiation
Accidents can occur within a short time → measurement-based judgment is essential

Hydrogen Sulfide (H2S) Risk

Smells like rotten eggs, but the sense of smell is deadened at high concentrations
A toxic gas that can cause respiratory irritation, loss of consciousness, and death
Judgment must be based on concentration (ppm), not odor

FIX800 Gas Detector

Continuously measures oxygen (O2) and hydrogen sulfide (H2S)
Installed at key locations around the reservoir tank for immediate hazard verification
Enables data-driven safety management rather than reliance on experience

FIX-DS Gas Concentration Display Board

Measured gas concentrations can be checked directly on site
Outdoor waterproof design suited to the reservoir tank's surrounding environment
Workers and supervisors can share the same information

Reservoir tank safety management needs to shift from occasional inspection to continuous monitoring
Oxygen deficiency and hydrogen sulfide cannot be judged by sight or smell
The FIX800 + FIX-DS system enables hazards to be detected in advance, preventing accidents

A FIX800 gas detector and FIX-DS gas concentration display board were installed for O2/H2S two-gas monitoring at this reservoir tank. The display board is fully waterproof and continues to operate reliably in rain and wind.

Installation is available nationwide.
