Description
Overview
GAOTek Handheld Air Sampling Pump for NO2 Detection is based on advanced infrared and electrochemical technology for measuring 100% LEL, 1000 ppm CO, 30% O2, and 100 ppm H2S concentration, with optional H2, CO, and gas flow items. Compact, rugged, and robust, the portable multi-gas detector is well-suited for many applications where the presence of multiple gases needs to be monitored (e.g., underground coal, digesters, methane recovery, waste and water treatment).
Features
- Detects 4 gases with a resolution of 0.5% vol/1ppm
- High & low alarm function: sounds, lights, and vibrates
- Digital LCD display: Displays real-time gas concentration value with backlight
- Durable power supply: rechargeable battery that can last for more than 12 hours
- Data logger & transfer in real time
