Dynamic Gas Mixing and Calibration Category lightweight portable system for calibration of gas analyzers used in air monitoring stations
Product Description:
MR-DF3 portable high-precision dynamic gas distribution meter is a compact, lightweight gas calibration device specifically engineered for environmental monitoring applications. This portable instrument delivers exceptional precision in dynamic gas distribution, enabling accurate preparation of standard gas samples for calibrating gas analyzers used in environmental protection departments, air quality monitoring stations, and pollution detection facilities.
The device features a battery-powered design with more than 20 hours of continuous operation after power failure, making it ideal for field environmental monitoring operations where reliable power sources may be unavailable. Its portable form factor allows easy transportation to remote monitoring sites, enabling on-site calibration of ambient air quality monitors, emission analyzers, and pollution detection equipment. The system utilizes high-precision stainless steel mass flow controllers and high-precision rotameter to ensure high system gas distribution accuracy and reliable quality, while the large LCD screen provides stable system operation and easier user interface for field technicians working in various environmental conditions.
Features:
· Portable design weighing less than 8kg for easy field deployment
· Battery-powered operation with 20+ hours continuous runtime after power failure
· High-precision stainless steel mass flow controllers for accurate gas distribution
