Portable Oxygen Detector Introduction
Portable oxygen detector is a gas detector which can be easily carried to the site to detect oxygen concentration and has the function of sound and light alarm. It is mainly used to detect oxygen gas concentration in the target environment. Portable oxygen detector is designed for the convenience of users to take to the site for testing, using a high performance oxygen sensor. The instrument has the features of simple operation, complete functions, high reliability, LCD display, built-in vibration alarm function, etc., suitable for steel, petroleum, chemical, coal mine underground or underground pipeline, tunnel and other underground engineering around the air environment oxygen gas concentration determination and overlimit alarm.
Portable Oxygen Detector Features
1, high quality sensor, highly sensitive probe
Responsive, quick response, accurate measurement.
2. Mechanics principle, humanized design
Anti-slip design is based on the principle of human mechanics, so that we can strengthen the comfort of human body under the premise of ensuring the sensitivity and accuracy of the product, so that the product is in line with human operating habits.
3. 200,000 pieces of data storage/large capacity
One key export/quick and convenient, you can enter the menu to view, browse/delete records.
4, lithium battery power supply lasting endurance
Rechargeable lithium battery, large battery capacity, long standby time, support for mobile power supply.
5, multiple alarm function over the limit
When the detected gas is more than the set gas value, the sensor opens the light alarm, high decibel buzzes, the instrument is marked red, timely reminder, high safety.

What is oxygen?
Oxygen is a kind of elemental form of oxygen element, chemical formula O2, its chemical properties are relatively active, and most of the elements can react with oxygen. It is not very active at room temperature and does not interact easily with many substances. But at high temperature, it is very active, can directly combine with a variety of elements, which is related to the fact that oxygen atom is second only to fluorine in electronegativity.
What is an O2 sensor?
An O2 sensor is an electronic device that measures the proportion of oxygen (O2 gas or liquid present in the analysis).
The most common application is to measure the concentration of oxygen in the exhaust gas of internal combustion engines in vehicles such as automobiles, in order to calculate and, if necessary, dynamically adjust the air-fuel ratio so that the catalytic converter can operate optimally, and also to determine whether the converter is operating properly. Divers also use similar equipment to measure the partial pressure of oxygen in breathing gases.
Scientists use oxygen sensors to measure respiration or oxygen production, and use another method. Oxygen sensors are used in oxygen analyzers and are widely used in medical applications such as anesthesia monitors, respirators and oxygen concentrators.
What are the common types of oxygen sensors?
Electrochemical oxygen sensor, fluorescent oxygen sensor, zirconia oxygen sensor.
