Wastewater plant portable delivery — NH₃, H₂S, CH₃SH — VPE Korea

Portable gas detectors for a wastewater treatment plant (Gyeongju, Gyeongbuk) — NH₃, H₂S, CH₃SH plus O₂ and combustibles.

Hello from VPE Korea. Final sewage plants collect flows for terminal treatment. We supplied two GasTiger 2000 units: one odor bundle and one confined-space safety bundle.
Odor unit — NH₃ 0–50 ppm, H₂S 0–50 ppm, CH₃SH 0–10 ppm.
Safety unit — O₂, CO, H₂S, Ex, CO₂ per site standard (see datasheet photos).

Two instruments were required to quantify odor precursors while simultaneously guarding workers with live oxygen readings.

Methyl mercaptan stinks at extremely low levels; it is tricky on portables, but Wandi GasTiger 2000/6000 can host a 0–10 ppm CH₃SH cell when specified.

Even with ventilation running, NH₃ climbed above 0.5 ppm beside the process—without fans other species would likely rise too.

We usually deliver in person and train operators because misuse shortens expensive sensors—hands-on commissioning is part of our service.
