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.

Septic Tank FIX800 Gas Detector (O2 CO CO2 H2S) with FIX-DS Concentration Display

Project Details

Septic entry package: FIX800 measuring O₂, CO, CO₂, and H₂S with a FIX-DS board at the hatch so crews read concentrations before unlocking.

Inside the tank the FIX800 sensor head alarms on light and sound when any channel exceeds setpoints.

The FIX-DS concentration display installed at the septic tank entrance is linked to the detector, so it rings the alarm in real time whenever hazardous gas is detected inside. Crews check the confined-space condition on the display before entry so work proceeds only when it is safe.

★ WANDI FIX800 (O2 / CO / H2S / CO2) Key Features ★

Fixed monitoring for "before entry" into septic tank / manhole confined spaces — continuously watches for hazardous gas and oxygen deficiency before and during work to prevent accidents.

Simultaneous 4-gas monitoring: O2 checks for oxygen deficiency/excess (the core defense against asphyxiation accidents); CO monitors carbon monoxide poisoning risk; H2S is the representative toxic gas in septic tank and wastewater systems (highly lethal); CO2 is used as an indicator of poor ventilation and asphyxiation risk.

Favorable for alarm operation that speeds up on-site response — alarm interlocking lets workers and managers recognize hazards immediately, enabling fast action such as ventilation, evacuation, or access control.

Combined with the FIX-DS display, visibility is maximized: the detector monitors at its installation location while the display shows readings at the entrance/manager's position, making work control easier.

Measurement is precise with FIX800, control is fast with FIX-DS — together they let you systematize "pre-entry safety confirmation" for septic tanks and confined spaces.
