Chlorine (Cl₂) measurement with GasTiger 2000 — water treatment — VPE Korea

Hello from VPE Korea. Today: GasTiger 2000 for Cl₂ (chlorine), widely used in water disinfection and semiconductor-related chemistry. Chlorine is both acutely toxic and a strong oxidizer that intensifies fire behavior.

We supply chlorine analyzers to municipal water departments and wastewater facilities so engineers can work safely. Chlorine (Cl₂) and chlorine dioxide (ClO₂) are powerful disinfectants—and among the most hazardous gases on site.

Reference limits: Cl₂ — TWA 1 ppm / STEL 3 ppm. ClO₂ — TWA 0.1 ppm / STEL 0.3 ppm.

Even below about 5 ppm, chlorine can harm people and equipment, so choose a low-range, high-resolution Cl₂ sensor appropriate to the hazard.

Detecting tiny leaks matters: loud (>95 dB) audio and vibration alarms protect crews when concentrations rise unexpectedly.

Checklist ① Korean UI support ② Data logging and chart review ③ Domestic service—repairs often within about one week ④ Optional calibration certificates (extra fee) ⑤ Up to three toxic sensors (configuration varies by gas family).

Always match the instrument to the target gas. Electrochemical cells can show cross-interference; consult a specialist before finalizing sensor chemistry. Thank you for reading this Cl₂ overview.
