Check 02 Plus Oxygen Analyzer
Model: IRC450 (replaces IRC400)
The Invacare Check O2 Plus Oxygen Analyzer is a single economical instrument that reports all the operating parameters necessary for performing oxygen concentrator checks. It is an efficient and cost-effective analyzer designed with technicians in mind.
The Invacare Check O2 Plus Oxygen Analyzer is three analyzers rolled into one:The IRC450 checks oxygen concentration, flow rate and patient outlet pressure on any oxygen concentrator. What's more, it requires no routine calibration, and there's no fuel cell to replace.
The Check O2 Plus can measure pressure in PSI or kPa. The Check O2 Plus is factory set to measure in PSI.
The Check O2 Plus is an oxygen analyzer designed to check the oxygen concentration, flow and outlet pressure of oxygen concentrators. The Check O2 Plus provides unparalleled performance and reliability from its advanced design that includes the following features and operational benefits:
- Accurate oxygen measurements
- No in-field calibration required
- Convenient ability to measure pressure in PSI or kPa
- Durable, compact design
- Large, easy-to-read, liquid crystal display (LCD)
- Shielded, reinforced sample gas inlet port
- Long battery life with 2 AA batteries
- Auto-off after 4 minutes
- Low battery indication
- Self-diagnostics
- Easy to clean
Warnings:The Check O2 Plus is for use only by trained personnel and is for checking oxygen concentrators only.
The Check O2 Plus Oxygen Analyzer measures oxygen concentration and flow using ultrasound technology and measures pressure using a piezoresistive silicon pressure sensor.
The Check O2 Plus Oxygen Analyzer is a tool used to measure oxygen purity, flow and pressure at the outlet of an oxygen concentrator. It is not intended to be used by patients who are prescribed oxygen, nor is it intended to continuously monitor or confirm oxygen delivery to a patient.
The Check O2 Plus Oxygen Analyzer is intended to be used in an environment where oxygen concentrators are being serviced or repaired. This includes Hospitals, Nursing Homes, Extended Care Facilities, Patient Homes, and Respiratory Device Service and Repair Centers.
Not for use in anesthesia applications or for measuring oxygen concentration from any sources other than conventional oxygen concentrators.
Effects of Other Gases:The Check O2 Plus is designed to measure two different types of gas mixtures:
- Oxygen, nitrogen and argon from oxygen concentrators
- Pure oxygen during calibration verification mode
Any other concentrations or combinations of gases will cause the Check O2 Plus to measure oxygen concentration incorrectly.
Effects of Low Flow in Oxygen Concentrators:Oxygen concentrators function on the principle of removing nitrogen gas from air, leaving concentrated oxygen and argon at a specific oxygen to argon ratio. This operating principle may be altered when concentrators are set to flow at the low end of their operational range. At low flows they may output a low oxygen concentration, e.g. 85% to 91%, for reasons other than high nitrogen, possibly due to an increase in argon content. The Check O2 Plus requires that the ratio of oxygen to argon remain constant in order to guarantee an accuracy of +/-1.5% oxygen.
Error Codes:The Check O2 Plus has self diagnostic features built into the software to detect faulty readings outside of normal operating ranges.
