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 H₂ and O₂ Gas Monitor Delivery — Cheonan, Chungcheongnam-do

FIX800 Fixed H₂ and O₂ Gas Monitor — Delivery to Cheonan, Chungnam

This delivery features the FIX800 fixed gas concentration monitor configured with two sensor channels.

Sensor Configuration

O₂ (oxygen): 0–5% vol — Low-concentration oxygen sensor to detect oxygen generation or enrichment
H₂ (hydrogen): 0–40,000 ppm — Triggers the beacon alarm when hydrogen exceeds the configured threshold

The low-range oxygen sensor monitors for oxygen generation, while the hydrogen sensor provides immediate on-site alarm annunciation via beacon when concentrations rise.

Kit Contents

Standard kit includes the main unit, power adapter, infrared remote control, and factory calibration certificate.

Power-On Boot Sequence

At power-on, the display progresses through: brand logo → product configuration → alarm mode and range → one-minute warm-up screen.

H₂ channel display sequence:

Live measurement display:

After the one-minute warm-up, the main measurement screen appears.

Alarm and Beacon Operation

When alarm thresholds are exceeded, the alarm lamp activates together with the beacon and buzzer.

Frequently Asked Questions

Q1. Why is the O₂ sensor configured for the low range of 0–5% vol?

This installation is in a process environment where oxygen is generated, so the purpose is to detect oxygen enrichment rather than deficiency. The 0–5% vol low-concentration range enables precise detection of oxygen generation at trace levels — more suitable for research, laboratory, or specialized process environments than a standard 0–25% vol deficiency-monitoring range.

Q2. Why does the H₂ sensor cover 0–40,000 ppm?

Hydrogen's LEL (lower explosive limit) is 4% (40,000 ppm). The 0–40,000 ppm range covers the entire flammable concentration band — from early-stage trace leak detection through to imminent explosion risk — providing continuous, comprehensive monitoring across the full hazardous range.

Q3. Can O₂ and H₂ sensors be installed simultaneously in one FIX800?

Yes. The FIX800 supports up to 4 sensor slots, allowing both O₂ and H₂ sensors to be installed together for independent real-time monitoring of each gas. Alarm thresholds are configurable per channel.

Q4. What is the factory calibration certificate used for?

The factory calibration certificate documents the pre-delivery inspection results, confirming that sensor response and measurement accuracy meet the specified performance standards. It serves as supporting documentation for industrial safety audits, certification inspections, and on-site commissioning records.

Q5. What settings can be adjusted with the infrared remote control?

The remote allows first and second-stage alarm thresholds, output signal mode, and measurement unit selection to be adjusted from a safe distance. This is particularly valuable when managing instruments installed in hazardous areas where direct physical access to the unit is not safe.
