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.

Phosphine (PH3) Fixed Gas Detector FIX800 — Safety Solution for Grain Warehouses, Silos and Port Fumigation

Phosphine (PH₃) leaks during and after fumigation can go undetected in unmanned facilities and spread to neighboring areas. WANDI FIX800 fixed gas detector provides 24/7 monitoring of 5 gases simultaneously, keeping grain warehouse and port fumigation sites safe.

Phosphine (PH3) Fixed Detection — Why FIX800 Is Essential for Grain Warehouses and Ports

Phosphine (PH₃) is the most widely used fumigant gas for grain storage pest control. During or immediately after fumigation, PH₃ concentrations can reach dangerous levels in and around storage facilities. Fixed 24-hour monitoring with FIX800 is essential to detect external gas migration and protect workers and neighboring areas.

Concentration (ppm)	Duration	Health Effects
0.3 ppm	8 hr TWA	Korean OSHA limit
2–4 ppm	Short	Headache, nausea, chest pain
50 ppm	30–60 min	Pulmonary edema, cardiac arrest
400 ppm	Immediately	IDLH — fatal

In Goodyear, Arizona, a family of three died after phosphine gas from a nearby food storage facility fumigation leaked into their home's basement. Poor facility sealing and lack of external leak monitoring were identified as key causes. (Source: U.S. EPA Enforcement Case, 2015 / Associated Press)

How FIX800 Could Have Prevented It

1External leak monitoring: FIX800 installed outside the warehouse immediately detects PH₃ migration during fumigation.
2Safe re-entry confirmation: FIX800 monitors PH₃ concentration decline to automatically confirm when safe re-entry is possible.
35-gas monitoring: Simultaneously tracks PH₃ + O₂ + EX + CO + H₂S for comprehensive hazard coverage.
