Mô tả sản phẩm: Thiết bị phân tích sự đốt cháy trong khai khoáng Land FGA 900series
Overview:
The FGA 900 series of combustion efficiency monitors use dual sensor technology to measure the levels of up to Carbon Monoxide (CO) and Oxygen (O2) in a single compact unit.
Key Features:
- Fully integrated system in a single compact box - no additional components required
- Suitable for a wide range of applications - up to 3 gases in a single analyzer
- Simple installation - locate the analyzer anywhere, including outside locations
Key Benefits:
- Combustion efficiency measurement - for optimizing process efficiency where conditions are changing
- Low maintenance - straightforward servicing without specialist skills
- Proven high performance - dual sensor measurement technique, Television and MCerts approved/Certified to US EPA standards
