TS Korea — Tunnel CO and NOx Monitoring with GasTiger 2000

Hello from TS Korea. This project used a portable GasTiger 2000 to manage carbon monoxide and nitrogen oxides inside a road tunnel.

Reference limits: CO below about 70 ppm and total NOx below about 20 ppm for tunnel air-quality planning (illustrative values from municipal monitoring reports).

Because CO is invisible and odorless, continuous checks are vital—especially in long tunnels or after incidents where concentrations can spike without warning.

The supplied unit was a GasTiger 2000 with a 0–100 ppm CO channel. Call TS Korea for tunnel gas-safety questions.
