University Lab Helium / Nitrogen O₂ Monitoring

University research laboratory
A laboratory that uses helium & nitrogen.

The installation was carried out to measure oxygen concentration inside the laboratory in real time and to monitor it in real time via a display board as well.

Nitrogen (N₂) and helium (He) are colorless and odorless, so a leak is difficult to notice by human senses, and when either gas leaks it displaces indoor oxygen, creating a risk of oxygen deficiency (reduced O₂).

For this reason, rather than "occasionally measuring with a single handheld meter," continuous (24-hour) monitoring plus immediate alarming is the core of proper safety management.

The combination suited to this purpose is FIX800 + FIX-DS.

★★★ FIX800 (Installed Oxygen Concentration Detector) ★★★

• Fixed continuous measurement: installed at hazardous points inside the laboratory (around gas use, storage, and piping areas) for constant monitoring
• Flexible gas configuration: can be configured as O₂ only, or as a combined setup such as O₂/CO/H₂S/CO₂ depending on the site
• Alarm-based safety response: immediately signals a hazard through an alarm when the concentration becomes abnormal
• External integration output: supports signal interfaces such as RS485 (Modbus) and 4–20mA for linking to display boards, control systems, or equipment interlocks

★★★ FIX-DS (Oxygen Concentration Display Board / LED Sign) ★★★

• "At-a-glance" checking at the entrance: laboratory interior readings can be checked directly from the corridor or entrance
• Real-time response (minimal display delay): responds within a maximum of 1 second when linked
• Signal input compatibility: supports RS485 (Modbus) / 4–20mA input

Wishing you continued safety at work.
