Description:
- O₂ & NH₃ & H₂S adopt high-precision electrochemical sensors;
- CO₂ is equipped with stable NDIR non-dispersive infrared sensor, avoiding the aging and poisoning defects of electrochemical sensors for long-term CO₂ measurement.
It supports dual sampling modes: built-in pump suction (1L/min flow) and diffusion sampling. The pump suction probe can go deep into narrow pipelines, sludge tanks, underground wells and sealed containers to extract gas samples for rapid quantitative testing. The LCD screen synchronously displays the concentration value, unit and alarm state of four gases at the same time, and can store up to 9999 groups of alarm data for later traceability and filing.
With Ex ib IIB T3 explosion-proof grade and IP65 dustproof and waterproof shell, the continuous working time can reach 100 hours under diffusion mode. The machine is equipped with sound-light-vibration triple alarm, which can effectively remind operators of gas over-limit risks in noisy on-site environments. Widely used in municipal environmental protection, breeding industry, waste disposal, chemical enterprises and confined space entry safety pre-inspection.
