Description:

This portable N2 nitrogen gas detector is a professional safety measuring instrument for nitrogen concentration monitoring and oxygen‑deficiency risk warning. Nitrogen is widely used for inert protection, food anti‑oxidation packaging, pipeline purging and laboratory gas supply. Nitrogen is colorless and odorless inert gas, excessive nitrogen leakage will displace oxygen in air and lead to suffocation hazard for on‑site personnel without any early warning symptom. This detector is equipped with high‑stability sensor, fast response, low zero drift and stable measuring performance. It continuously collects and displays real‑time N2 concentration data of ambient atmosphere. When nitrogen concentration exceeds preset alarm threshold, sound‑light dual alarm will activate, reminding operators to ventilate the area and avoid suffocation accidents. Adopting ergonomic lightweight handheld housing, it supports long‑time on‑site patrol and confined space entry inspection. Adjustable alarm threshold and low power consumption make it ideal for daily safety inspection in food packaging workshops, chemical inerting sites, nitrogen gas storage rooms and laboratories.
