FAQ about Cubic ultrasonic Oxygen Sensor Gasboard7500B to Detect Oxygen Concentration?

No Need of calibration

1. what is Cubic oxygen sensor gasboard7500B?

ultrasonic oxygen sensor gasboard7500B is an economical gas sensor used to detect oxygen concentration in binary gases. Adopting ultrasonic detecting technology, gasboard7500B has better property than electro-chemical and other oxygen sensors. It has functions includes data display, online monitor, status alarming and has been widely used in home and medical oxygen generator, ventilator, anesthetic machine, etc.

The main features are no calibration, stable performance, high accuracy, long lifespan , low cost,etc.

2.How does ultrasonic technology used to detect oxygen concentration?

Ultrasonic concentration detection theory: when the binary gas mixture composition has molecular weight difference, sound travel speed varies from different gas composition. Ultrasonic technology is generally used for testing the concentration of binary mixture such as A in A+B ( A and B have different density and different travel speed).

3. How can we use gasboard7500B to measure 99.99% oxygen concentration?

We can calibrate with 100% O2 and compressed air in ventilator application for air and oxygen mixture.

4. Should the ultrasonic measurement be influenced by application environment?

The ultrasonic technology is mainly influenced by moisture content, so the gas should be better proceed dehydration and dehumidification before measurement, the moisture content will have influence to the gas concentration measurement.
