Som livets kilde og et vigtigt industrielle element er nøjagtig måling af iltkoncentration afgørende inden for mange områder. Håndholdte iltanalyzatorer, med deres bærbarhed, hastighed og nøjagtighed, er blevet et værdifuldt redskab til on-site testning. Denne artikel vil fokusere på tre centrale anvendelsesscenarier: måling af iltkoncentratorudgangskoncentration, overvågning af iltindholdet i fødevareemballager og måling af iltkoncentration i omgivende luft.
1. Oxygenkoncentrator Koncentrationsanalysatorer:
For brugere, der har brug for hjemme-iltbehandling, er iltkoncentrationen, der udledes af en iltkoncentrator, direkte relateret til effektivitet og sikkerhed. En enhed med en nominel iltudgang på 93% ± 3% kan opleve ydeevnedegeneration på grund af slid på molekylesieben, aldring af komponenter eller spændingsudsving.
(1).Instrumentrolle:
Brugeren forbinder instrumentet til iltkoncentratorens udgang via et tyndt forbindelsesrør, og instrumentet viser iltkoncentrationen (%VOL) ved den aktuelle flowhastighed i realtid.
(2). Tekniske funktioner:
Højt område og høj nøjagtighed: Specialiseret til måling af høje iltkoncentrationer (typisk 70%-100%), med en nøjagtighed på ±1% eller højere, kan den opdage selv den mindste nedgang i koncentrationen.
Lav modstandsdesign: Den specielt designede interne luftvej minimerer luftstrømsmodstanden, hvilket sikrer, at målingen ikke påvirker den normale drift og udstrømningshastighed af iltkoncentratoren, og dermed sikrer nøjagtige målinger.
Brugervenlig: Enkel betjening og intuitive resultater. Typisk udstyret med en lavkoncentrationsalarm, som automatisk udløser en alarm, når målingen falder under en sikker tærskel (f.eks. 82%), hvilket opfordrer brugeren til at udføre vedligeholdelse eller udskifte enheden.
Vores virksomheds CY-12C håndholdte iltananalysatorer og ZY-20C iltananalysatorer anvender iltfølere importeret fra Storbritannien. De kan overvåge iltkoncentrationen i iltkoncentratorer i henhold til kundens behov med nøjagtigheder på henholdsvis ±3% og ±1%.
2. Fødevareemballage Headspace-Analysator: En "Detektiv" for Kvalitetsbevarelse
I fødevare- og medicinalindustrien er resterende ilt i emballagen en af de vigtigste årsager til produktskader og forringelse. Kerne-teknologien i modificeret atmosfære-emballage (MAP) og nitrogen-fyldt emballage er at reducere iltindholdet i emballagen.
(1).Instrumentrolle:
This instrument acts like a "microscopic detective," specifically examining the gas composition in the headspace of packaging bags (bottles, cans, etc.). It is equipped with an extremely fine sampling needle. Upon piercing the package, a micropump extracts a small amount of gas, which the sensor rapidly analyzes and directly displays in %Vol or ppm.
Our company's ZY-20C oxygen analyzer, combined with a sampling needle and syringe, can measure the oxygen concentration within packaging bags. The detection range is 0-100% vol, with a resolution of 0.01% vol at low concentrations.
(2).Technical Features:
Non-destructive Testing: The sampling needle is extremely fine, creating a negligible hole upon insertion, which does not affect the packaging seal or the shelf life of the remaining product, achieving "minimally invasive" or "non-destructive" testing.
High Sensitivity and Accuracy: The instrument can accurately detect extremely low oxygen concentrations below 0.1%, which is crucial for controlling product quality and verifying the sealing performance of packaging lines.
Hygienic and Robust: The probe is typically made of stainless steel, making it easy to sterilize and preventing cross-contamination. The instrument's robust structure is suitable for production workshop environments.
Summary: It is an indispensable part of the quality control system, safeguarding product freshness and safety from the source of the production line.
3. Ambient Oxygen Detector: A "Sentinel" for Life Safety
Abnormal oxygen concentrations are a major safety hazard in confined spaces (such as ship cabins, underground pipelines, and fermentation tanks) or locations where gas leaks may occur (such as laboratories and nitrogen flushing areas). Concentrations that are too low (<19.5%) can lead to asphyxiation due to lack of oxygen; those that are too high (>23.5%) increase the risk of explosion.
(1).Instrument Role:
This type of instrument serves as a "loyal sentinel" for maintaining industrial safety and personnel health. It uses diffusion sampling to continuously monitor the ambient oxygen concentration.
(2).Technical Features:
Real-time Monitoring and Alarm: Capable of 24-hour continuous monitoring, it features high and low concentration alarm thresholds. If concentrations become abnormal, an ultra-high decibel alarm and a flashing bright light will immediately trigger, alerting personnel to evacuate immediately.
Intrinsically Safe Design: Many professional models are intrinsically safe (Ex) certified, allowing safe use in flammable and explosive environments without becoming an ignition source.
Rugged and Durable: Highly dustproof, waterproof (IP rating), and drop-resistant, it can withstand a variety of harsh industrial environments.
Data Logging: Advanced models support data logging for easy traceability and analysis.
Our company produces portable oxygen concentration detectors and fixed oxygen concentration detectors, which can detect the oxygen concentration in the air and send alarm signals if it is too low or too high.
