Labtron Portable H₂S Gas Detector measures hydrogen sulfide concentrations across selectable ranges up to 0–10,000 ppm, with a response time of ≤10 seconds.

The electrochemical detection system uses an internal sampling pump with a flow rate of up to 1 L/min. Its LCDs gas readings in ppm or mg/m³, while adjustable alarm functions provide sound, light, and vibration alerts. USB data output supports downloading and printing measurement records.

Manufactured for hydrogen sulfide monitoring in industrial workplaces and laboratories, this h2s gas monitor supports petrochemical, chemical, and environmental applications.
