Oxygen Probe Suppliers

An oxygen probe is a device used to measure the concentration of oxygen in a gas or liquid. It typically consists of a sensor that contains a ceramic material with a thin layer of metal oxide on its surface. When exposed to oxygen, the metal oxide reacts and produces an electrical signal that is proportional to the oxygen concentration. This signal is then sent to a meter or computer for analysis. Oxygen probes are commonly used in industrial processes, such as steel production and wastewater treatment, as well as in medical settings to monitor oxygen levels in patients.

There are several types of oxygen probes available in the market, including zirconia probes, electrochemical probes, paramagnetic probes, and infrared probes. Zirconia probes are the most commonly used and measure oxygen concentration by detecting the difference in oxygen partial pressure between the ambient air and a reference gas. Electrochemical probes use a chemical reaction to generate an electrical signal that is proportional to the oxygen concentration. Paramagnetic probes use the magnetic properties of oxygen to measure its concentration, while infrared probes measure the absorption of infrared light by oxygen molecules. Each type of probe has its own advantages and disadvantages, and the choice of probe depends on the specific application and requirements.

The accuracy range of an oxygen probe can vary depending on the specific model and manufacturer, but typically falls within ±1% to ±5% of the measured value. To ensure accuracy, it is important to calibrate the probe regularly using a known reference gas or solution. Additionally, proper storage and handling of the probe can also impact its accuracy, so following the manufacturer's instructions for maintenance and use is crucial.

An oxygen probe, also known as an oxygen sensor or oxygen analyzer, is used to measure the concentration of oxygen in a gas or liquid. Typical applications of an oxygen probe include:

• Medical: Oxygen probes are used in medical settings to monitor the oxygen levels in a patient's blood during surgery or in intensive care units.
• Industrial: Oxygen probes are used in industrial processes such as steelmaking, chemical production, and wastewater treatment to monitor and control oxygen levels.
• Environmental: Oxygen probes are used in environmental monitoring to measure the oxygen levels in bodies of water, such as lakes and rivers, to assess the health of aquatic ecosystems.
• Aerospace: Oxygen probes are used in aerospace applications to monitor the oxygen levels in aircraft cabins and spacesuits.
• Automotive: Oxygen probes are used in automotive engines to monitor the oxygen levels in exhaust gases, which helps to optimize fuel efficiency and reduce emissions.

Food and beverage: Oxygen probes are used in food and beverage production to monitor and control the oxygen levels in packaging and storage environments, which helps to extend the shelf life of products.

The lifespan of an oxygen probe can be affected by various factors such as the type of probe, the quality of the materials used, the operating temperature and pressure, the presence of contaminants or corrosive substances, the frequency of use, and the maintenance and calibration practices. Other factors that can impact the probe's lifespan include the accuracy and sensitivity of the measurement, the stability of the signal, and the compatibility with the measurement system. Proper handling, storage, and cleaning of the probe can also help extend its lifespan.

However, in general, oxygen probes should be calibrated before each use or at least once a day if used continuously. The calibration process involves immersing the probe in a solution with a known oxygen concentration and adjusting the probe's readings to match the known value. The exact calibration process may vary depending on the specific type of oxygen probe being used. It is important to follow the manufacturer's instructions for calibration to ensure accurate readings.

An oxygen probe requires regular maintenance to ensure accurate readings. The maintenance requirements include cleaning the probe with a soft cloth and a mild detergent, checking the calibration regularly, replacing the electrolyte solution, and replacing the sensor after a certain period of use. It is also important to store the probe properly when not in use and to handle it carefully to avoid damage.

Choosing the right oxygen probe for your specific application involves considering factors such as the type of gas being measured, the temperature and pressure of the environment, the level of accuracy required, and the desired response time. Other factors to consider include the probe's durability, compatibility with other equipment, and ease of maintenance. It is important to consult with a knowledgeable supplier or manufacturer to ensure that you select the most appropriate oxygen probe for your needs.

The price range of an oxygen probe can vary depending on the type and quality of the probe. Basic probes can cost around $50, while more advanced and high-quality probes can cost upwards of $1000. Factors that can affect the cost of an oxygen probe include the type of sensor used, the accuracy and precision of the measurement, the durability and lifespan of the probe, and any additional features such as temperature compensation or digital display. The brand and supplier of the probe can also affect the cost.

However, in general, the warranty and return policy for an oxygen probe may vary depending on the manufacturer or seller. It is important to read the terms and conditions carefully before purchasing the product to understand the warranty and return policy. If you need to claim the warranty or return the product, you may need to contact the manufacturer or seller and provide proof of purchase and the reason for the claim or return.
