Oxygen Index Module은 샘플의 산소지수인 OI 및 LOI, COI를 측정하는 제품입니다. 사용이 간편하고, 보기가 편한 디지털 디스플레이를 채용하고 있으며, 산소지수 뿐만 아니라 분당 nl의 flow rate, 컬럼온도(°C)를 곧바로 가리켜 줍니다. Concept Equipment의 OIM은 매우 최신의 제어기술을 활용하여, 사용법이 아주 간편합니다. 예를 들어, 터치스크린으로 산소농도를 빠르게 선택할 수 있고 산소 및 질소가스 밸브를 자동으로 조정할 수 있습니다. 이는 수동으로 밸브를 조작하는 대부분의 다른 제품과 차별화된 기능입니다.
또한 OIM 전면의 디스플레이 패널은 시험 중 침니 및 침니온도, 경과시간을 통해 기기 상태, 산소농도, 가스유속을 보여줍니다. 터치스크린 디스플레이패널에서 선택 가능한 “Autocal’’ 기능을 이용하면, 초기값 및 스판 범위 보정이 기기에 의해 자동으로 이루어지게됩니다.
Specification & Features
- Home” system set up screen with “Run” screen to perform tests using easy to operate touch screen user interface.
- Digital display showing oxygen concentration, gas flow rate through the chimney, chimney temperature and lapsed time during the test.
- Oxygen concentration selected and instrument adjusts automatically.
- AutoCal facility calibrates zero and span range totally automatically.
- Fully automatic gas calibration.
- A state of the art, fast response oxygen transducer, accurate to ± 0.1%, is used for measurements.
- A mineral insulated thermocouple is installed inside the chamber to measure column temperature just beneath the sample.
- Ideal for use in quality control applications as well as a valuable tool for the development and analysis of new materials.
Technical Data & Requirments
- Electrical: 115 Volts AC 60Hz / 230 Volts AC 50Hz.
- Ambient Temperature: Operating 10°C to 35°C.
- Dimensions: 450mm (W) x 750mm x (H) x 450mm (D) Flow: Flow through column adjustable from 0 to 20 nl/min.
- Gas Supplies: Oxygen and Nitrogen at 2.6 Bar (38 psi) with a flow rate of 25 nl/min (normally bottled supply with in-line regulator and filter). No other restrictions should be used as this will reduce the flow rates.
- Oxygen Analyser: Range:0 to 100% Oxygen
- Repeatability (typical): ± 0.1% Oxygen
- Linearity (typical): ± 0.1% Oxygen
The Oxygen Index Module measures the oxygen index (OI, LOI or COI) for a range of samples.
It is simple to use, and utilises an easy to read digital display, indicating the oxygen index directly in % Oxygen, as well as the flow rate in nl/min and the column temperature in °C.
Our instrument utilises the very latest control technology and is extremely easy to use. For example, selection of oxygen concentration is by simple selection on the touch screen and the oxygen and nitrogen valves are adjusted automatically. This differs from most competitive products, where the valves need to be adjusted manually, which can be frequently time consuming and a tedious task. Also, on the front of the module there is a display panel showing instrument status, oxygen concentration, flow rate of gas flowing through the chimney, chimney temperature and lapsed time during the test. The “Autocal’’ facility is selected on the touch screen display panel and zero and span range calibrations are then performed automatically by the instrument.
