Hospital wastewater FIX800 O₂ monitor with LED scoreboard — VPE Korea

Hi from VPE Korea. Today: a large hospital wastewater plant using FIX800 for oxygen. Always verify oxygen and toxic levels before confined-space entry.

Poor ventilation with falling oxygen or rising toxics can escalate to fatalities.

Site: major hospital WWTP.
Measurement: single O₂ channel.
Display: one-channel LED board plus local FIX800 display.
Layout: LED at the entrance, detector inside the process area.

We have extensive WWTP experience, so after reviewing the hazard map with the owner we positioned the board and probes for fastest recognition.

The oxygen status panel includes beacons: below 18.5% or above 23% triggers color and sound so crews recognize danger immediately.

FIX800 can be ordered as oxygen-only or four-gas (O₂, H₂S, CO, combustibles) and specialty channels such as HF, Cl₂, or SO₂. Example: FIX800 + beacon + Cl₂ 10 ppm + EtO 10 ppm.

Detector and LED communicate over RS-485, so long cable runs stay stable without hunting noise.

We sealed wall penetrations with silicone, completed commissioning, verified numeric agreement between panel and transmitter, and tested beacons. Call us for any fixed-gas installation questions.
