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 Gas Detector Installation Completed at Confined-Space Wastewater Treatment Plant (Part 1)

Confined Space Wastewater Treatment Plant — FIX800 Gas Detector Installation Completed (Part 1)

This is the first installment introducing the FIX800 gas detector, including the unit itself and photographs documenting the on-site installation process. FIX800 is a fixed gas detector capable of measuring up to five different gases simultaneously, distinct from portable units. Configuration should be determined through expert consultation based on the specific application.

This particular case involved a facility that reached out for oxygen monitoring in a wastewater treatment plant confined space, along with gas and oxygen measurement for its laboratory.

Installation Specifications

Item	Details
Detector	FIX800 fixed gas monitor
Sensor capacity	Up to 5 gases simultaneously
Sensor configuration	O₂ (oxygen)
Installation environment	Wastewater treatment plant confined space
Location	Yongin-si, Gyeonggi-do

Site Survey and Configuration

The installation team first surveyed the site together with the facility's on-site manager to confirm the planned installation locations. Because confined spaces carry a high risk of serious accidents, oxygen and any hazardous gases must always be measured before entry. At this particular site, no hazardous gas was present, so only oxygen concentration was measured.

Alarm and Warning Light System

If the oxygen level drops too low, a warning light on the main unit sounds an alarm, and additional warning lights can be installed at any other location as needed.

At this site, detectors were installed at the entrance, the security office, and the general office.

Why Oxygen Concentration Monitoring Is Required

Legal compliance: Under Korea's Occupational Safety and Health Act, confined spaces must have oxygen and hazardous gas levels measured before any work begins
Preventing oxygen deficiency accidents: Work capacity declines when oxygen falls below 18%, and levels at or below 10% carry a risk of death
Confined space safety: Accident risk increases significantly as gas accumulates in an enclosed space

These photos show the installation work in progress. Working with a professional installation team, the system was installed cleanly and tailored to the customer's specific requirements. This particular site required a large-scale installation spanning three full days, which was completed successfully.

The FIX800 gas detector is essential equipment for industrial sites, helping maintain a safe working environment. Its ability to measure multiple gases simultaneously and provide real-time data monitoring supports a wide range of use cases and helps keep workers safer on the job.

FIX800 — Fixed Multi-Gas Detector Overview

Supports up to five gas sensors in a single unit — distinct configuration capability from portable detectors
Provides continuous fixed-point monitoring, suited to confined space applications requiring 24-hour gas surveillance
Optimal sensor combination is determined by site-specific risk assessment and expert consultation

Frequently Asked Questions

What is the maximum number of gases FIX800 can measure simultaneously?

FIX800 supports up to five gas sensors in a single unit, providing comprehensive multi-gas monitoring from a single fixed installation.

How should the gas sensor configuration be determined for a specific facility?

Configuration should be determined through expert consultation based on the specific gases present and risk factors at each individual site, rather than a one-size-fits-all approach.

Why is a wastewater treatment plant a typical FIX800 application?

Wastewater treatment facilities are classified as confined spaces under Korea's Occupational Safety and Health Standards, requiring continuous gas monitoring for worker safety — making FIX800's fixed, multi-gas configuration well-suited to this application.

How can configuration guidance be obtained for this type of facility?

WANDI Korea provides expert consultation on FIX800 configuration tailored to specific facility requirements, along with on-site installation services.
