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 Fixed O₂ Gas Detector with LED Display Board — Delivery to Changwon, Gyeongnam

FIX800 Fixed Oxygen (O₂) Detector with LED Display Board — Changwon, Gyeongnam

This article features a FIX800 fixed oxygen (O₂) gas detector delivered to a facility in Changwon, Gyeongsangnam-do.

Powering On — Status LED Check

With power applied, the green WORK LED illuminates at the top of the unit, indicating normal operation. This detector is configured as an oxygen (O₂) monitor. The center of the display shows the live O₂ reading, with MAX and MIN recorded values at the bottom.

Alarm Activation

When the measured concentration exceeds the configured alarm threshold, the red ALARM LED activates and the numeric reading on the display turns red — providing clear immediate indication of an abnormal condition.

Option — LED Display Board

When the LED display board option is selected, the detector and board ship pre-connected and configured — ready for installation without additional wiring setup.

At this customer's request, the display board was custom-produced with the label "Confined-Space Oxygen Concentration." Live oxygen readings are mirrored on the display in real time, making concentrations clearly visible at a distance.

Frequently Asked Questions

Q1. What do the FIX800 front-panel LEDs indicate?

The green WORK LED confirms normal operation. The red ALARM LED activates when a measured value exceeds the configured alarm threshold — at the same time, the numeric reading on the display turns red. If a beacon lamp is connected, audible and visual alarms also activate simultaneously.

Q2. Can the display board text be customized?

Yes. As shown in this case, the board was produced with custom text to match the measurement gas and application. Text such as "Confined-Space Oxygen Concentration" or "Gas Concentration Status" can be specified at time of order.

Q3. How does the display board connect to the FIX800?

The board receives the FIX800's RS-485 or analog output signal to display live readings. When the display board option is selected at order, the detector and board are pre-wired and configured before shipment — no additional on-site wiring is needed.

Q4. Does an oxygen-only detector satisfy confined-space safety requirements?

In environments where oxygen displacement by inert gases is the sole hazard, an O₂-only configuration provides a basic safety baseline. However, in spaces where toxic gases such as H₂S may also be present, a multi-gas sensor configuration is recommended. A site-specific assessment with a specialist is advisable before finalizing the configuration.

Q5. How is the reading checked when operating FIX800 without a display board?

The FIX800's built-in LCD displays live readings directly. Where the instrument is mounted out of easy viewing distance or in a location difficult to approach safely, adding a remote display board at the entrance improves convenience and pre-entry safety verification.
