RP-03Ultrasonic Oxygen Sensor
Gas Analyzer
Handheld rechargeable ultrasonic oxygen analyzer for fixed PSA oxygen concentrator oxygen percentage, flow, and outlet pressure measurement.
Product Introduction
The RP-03 handheld ultrasonic oxygen analyzer is a rechargeable meter developed by Winpower Technology Co., Ltd. Based on the same ultrasonic oxygen sensor technology as the RP-01, it measures the oxygen concentration, flow rate, and outlet pressure of fixed PSA oxygen concentrators. Oxygen concentration is determined from the different sound propagation times in oxygen and nitrogen; flow is measured by comparing sound propagation times with and against the gas flow direction; pressure is measured by an integrated pressure cell. The sensor is factory calibrated and does not require user recalibration.
Features
- Ultrasonic oxygen detection — measures O₂ concentration using sound-propagation-time difference
- Integrated flow measurement — bidirectional ultrasonic flow sensing for PSA concentrator output
- Integrated pressure measurement — detects outlet pressure of non-aggressive gases up to 100 kPa
- Rechargeable battery — portable handheld design for field service and production QA
- Factory calibrated — no customer calibration required; annual metrological check recommended
- Fixed PSA concentrator use — designed for oxygen percentage, flow, and pressure verification
Applications
Precautions for Use
- This product is only for detecting the output gas of fixed PSA oxygen concentrators and must not be used to monitor life-support systems.
- Do not calibrate the RP-03 with 100% oxygen.
- The RP-03 and all accessories that come into contact with oxygen should be kept free of oil and grease.
- Protect the device from moisture and keep away from fire or smoking during use.
- If the device has been stored below 5°C, allow it to reach room temperature before use.
- Empty or remove the humidifier bottle of the oxygen concentrator before connecting to prevent water ingress.
- Dust filtration is required during operation.
