The Portable Pinhole‑Type Nitrogen Detector (Model ES20B‑N2), designed to revolutionize food packaging safety and quality control. This compact, pump‑suction gas detector is engineered to precisely monitor nitrogen (N₂) levels and detect residual oxygen (O₂) and carbon dioxide (CO₂) inside sealed packages—ensuring optimal freshness and shelf life.
Why it matters
Nitrogen makes up about 78% of Earth’s atmosphere and is widely used in Modified Atmosphere Packaging (MAP) to replace oxygen, reduce oxidation, and prevent microbial spoilage in snacks, dairy, coffee, and other perishable foods .
Ensuring high-purity nitrogen (≥99.0%) is critical—any trace of oxygen or CO₂ can degrade product quality.
Key features of the ES20B
Pinhole pump‑suction sampling: Needle-based sampling enables fast, accurate measurements directly inside sealed packages.
Full-metal housing: Robust aluminum alloy construction, weighing ~0.46 kg, ensures durability and portability.
High-precision electrochemical sensor: Measures 0–100% VOL N₂ with 0.01% resolution, ±3% full-scale accuracy, and response time under 30 seconds.
Long battery life & USB output: Rechargeable 2600 mAh battery supports over 12 hours (or 20+ hours per PDF), charges in ≤6 hours, with USB data link.
Smart features: Multi-point calibration, temperature compensation, Chinese/English UI, and storage for 100,000 data sets ensure reliable, traceable results.
Alarm system & protection: Audible (>75 dB) and visual LED alerts, IP54-rated casing, and operating range from −20 °C to +50 °C make it suitable for harsh environments.
Certifications & support: Complies with CE, ATEX, SIL, RoHS, ISO9001/14001/45001; Safewill offers OEM branding, rapid 3-day production, calibration certificates, and technical assistance.
Ideal applications
The device targets food manufacturers using nitrogen flushing for packaged goods like spicy snacks, sunflower seeds, potato chips, beef jerky, milk powder, and bread—helping ensure consistent quality and regulatory compliance.
Market impact
With increasing consumer demand for food safety and longer shelf life, the ES20B offers manufacturers a portable, user-friendly tool to monitor internal gas composition. Its fast response, rugged design, and reliable data logging position it as a strategic asset for quality control teams.
Looking ahead
Safewill continues to expand its gas detection lineup, including multi-gas handheld and fixed systems tailored to industrial and environmental needs. The company emphasizes customization and rapid delivery to meet evolving market demands.
