WATER TEST

■ Overview
The needle-type oxygen sensor is a micro-invasive sensor designed to precisely measure the oxygen concentration inside a package. It plays an important role in the quality control of oxygen-sensitive products, such as in the food, beverage, and pharmaceutical industries. This sensor has a very small sensor chip and penetrates the rubber stopper or thin film of the package to measure the amount of oxygen inside. Since it directly measures the oxygen concentration, it can obtain accurate data with minimal error, making it an essential tool for ensuring long-term storage stability and product quality.

■ Features
High-precision measurement: Quickly and accurately measure residual oxygen, reducing measurement error
Micro-intrusive design: The sensor tip is very thin (<50 µm), allowing measurement without damaging the package
Versatile: Capable of measuring oxygen in liquids and gases
Fast response: Very short response time supports real-time measurement (t90 < 3 seconds)
No oxygen consumption: No oxygen consumption during measurement, allowing stable data to be obtained
Optimized quality control: Easily measure oxygen in food, beverage and pharmaceutical packages to enhance long-term storage

■ Specifications
Measurement range: 0 - 100 % O2 (gas phase), 0 - 45 mg/L (liquid phase)
Detection limit: 0.03 % oxygen, 15 ppb
Response time: Within 3 seconds in gas phase, within 10 seconds in liquid phase
Compatible: Compatible with aqueous solutions, ethanol and methanol
Durability: The sensor can be used for up to 5 years with proper storage
Temperature range: 0°C to 50°C
Cross sensitivity: Sensitive to organic solvents and chlorine gas

■ Applications
Needle-type oxygen sensors are used in a variety of applications for packaging quality control. They are particularly widely used in the following industries:

Food and beverage industry: Measure the amount of residual oxygen to prevent oxidation of products by oxygen and control quality

Pharmaceutical industry: Monitor the oxygen concentration inside packages to prevent deterioration of medicines and ensure product safety

Packaging industry: Measure the amount of oxygen inside sealed packages to ensure long-term storage of various products

Precise measurement of oxygen concentration using micro-intrusive sensors further strengthens quality control inside packages.
