Product Description
680L 4 Gas Calibration Gas – 32% LEL Methane, CO, O₂ (Facility-Scale Precision Calibration)
This 680L high-capacity 4 gas calibration gas is designed for facility-wide multi-gas detector calibration, featuring 50 PPM Carbon Monoxide (CO), 1.62% Methane (32% LEL), and 19.0% Oxygen (O₂) balanced in nitrogen.
This formulation supports low-range LEL validation across multiple detectors, making it ideal for multi-point calibration programs and advanced compliance environments.
