Oxygen sensor
Oxygen sensor is a kind of metallurgy detection probe which is designed to measure the oxygen content and temperature of the molten steel fast, accurately and directly.
1. Application: used for primary melting furnace, lf and rh furnaces and so on, oxygen probes measure oxygen activity of the molten steel and the oxygen activity of the molten steel in the treating process, which can guarantee the deoxidizer addition, shorten the refining time, help to develop new varieties, improve technology, and promote steel purity.
2. Main features and range of application:
Oxygen sensor has three types:
1)oxygen sensor for high ppm
2)oxygen sensor for low ppm .
3)oxygen sensor for ultra-low ppm.

Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc.
As an experienced Silicon Dioxide manufacturer and supplier, we has been supplying and exporting Silicon Dioxide for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

Our sunflower oil corresponds to the Premium grade. Ideal for frying and for salads. This is a good nutritious food product rich in vitamin E, as it is produced by cold pressing without chemical extraction. In the refining process, chemical solvents are also not used, which leaves the oil even after refining very rich in vitamins and vegetable fats with a minimum oxidation index, which gives an shelf life of up to 18 months.
I am sure you will be glad to have in your arsenal our competitive oil at a price corresponding to quality.

This protective mask cannot generate oxygen and should not be used in hypoxic environments.
It is not a N95 certified Mask for USA yet. Not intended as a replacement for gas masks and medical masks. Not for use if breathing is impeded or unsteady, or during sleep. DAILY USE: Suitable for adults daily travel protection, not suitable for toxic gas environment use.
FUJI developed the first infrared gas analyzer in Japan to use mass-flow sensors. Since then, we have supplied customers with various types of gas analyzers to support environmental preservation and control efforts. These efforts include measurements of atmospheric pollution and detection of low density of SOx and NOx, generated by incinerating facilities and boilers. FUJI's gas analyzers are widely used to monitor the atmosphere to help maintain a cleaner natural environment.
Sensors have an internal thermistor fully sealed for temperature monitoring. Sensors are housed in a polypropylene body for long-term use underground. Two head options include a diffusion head for field use and a flow-through head for laboratory use.
