Oxygen Analyzer OXA801

Serrax Technologies’ Oxygen Analyzer OXA 801 is a highly accurate and reliable instrument used to measure oxygen concentration in various environments. OXA801 is a microcontroller-based instrument that shows real-time O2 values. The instrument has an internal battery-operated pump to draw in an air sample. It is designed to provide quick and precise results with an accuracy of 2% at full scale. The concentration of oxygen (O2) in a gas mixture is measured by an oxygen analyzer, sometimes referred to as an oxygen gas analyzer or oxygen meter. These analyzers are widely utilized across a wide range of industries and applications where accurate oxygen level monitoring is essential for process improvement, quality assurance, and safety.

The key elements and characteristics of   a typical oxygen analyzer are as follows:

Sensor: The oxygen sensor is the main element of the analyzer and is in charge of identifying and calculating the amount of oxygen present in the gas sample. Oxygen sensors come in a variety of forms, including electrochemical, paramagnetic, and zirconia.

Electrochemical sensors: These sensors measure the oxygen content through an electrochemical process. Due to their small size and low power consumption, they are frequently employed in portable and handheld oxygen analyzer.

Display: The oxygen analyzer has a digital display that, often in percentage (%O2) or parts per million (ppm), displays the measured oxygen concentration in real-time.

Calibration: Oxygen analyzers must be periodically calibrated, just like all measuring devices, to ensure precise and trustworthy measurements. Setting the analyzer to a known oxygen concentration reference, usually in ambient air with a well-defined oxygen level, is known as calibration.

Sampling System: The analyzer’s sampling system is in charge of obtaining a representative gas sample from the process or environment that will be under test. The sampling system makes sure that the gas sample precisely and cleanly reaches the sensor.

Measurement Range: Oxygen analyzers are capable of measuring a variety of oxygen concentrations, ranging from trace levels to high concentrations.

Response Time: After being exposed to a change in oxygen content, the analyzer’s response time describes how quickly it can deliver a steady and accurate measurement.

Oxygen Purity Meter OPM250

Serrax Technologies’ Oxygen Purity Meter is designed to measure the purity of oxygen in various settings, including medical, industrial, and laboratory environments. This product features a robust sensor that can measure oxygen with a resolution of 0.1%, making it highly accurate and reliable.

It comes with a wide range of 0-100%, allowing for a broad range of applications. Additionally, it has a rapid response time of T90 <15 seconds, ensuring that users get real-time and precise results. This speed is further enhanced by a flow rate of >0 LPM, which enables efficient and timely measurement.

An instrument used to gauge the amount of oxygen present in a gas mixture is an oxygen purity meter, sometimes referred to as an oxygen analyzer or oxygen monitor. These devices are frequently used in a variety of fields, such as healthcare, manufacturing, aerospace, and diving, where accurate oxygen level monitoring is essential for quality assurance and safety.

The following are frequent key characteristics and capabilities of oxygen purity meters:

Measurement Range: The OPM250 probably has a specific range where it can measure oxygen concentrations with accuracy. Trace quantities (parts per million, or ppm) and large concentrations (percentage level) are examples of this range.

Accuracy: Oxygen purity meters should deliver accurate readings that are within the prescribed range. The instrument’s accuracy is often represented as a percentage.

Display: The oxygen content in the gas mixture being examined is displayed digitally on the majority of oxygen purity meters.

Sampling system: The instrument typically has a sampling system that enables the user to take a sample of gas for analysis from the source. In order to ensure representative gas samples and prevent contamination, the sampling system should be created.

Response Time: The amount of time it takes for the oxygen purity meter to accurately display a reading following the collection of a gas sample.

Portability: Oxygen purity meters can be benchtop or portable devices, depending on the application.
