Specification

The Pulse Oxygen Saturation (SpO2) Measuring

• Measuring range:0% - 100%
• Accuracy:70%-99%:+/-2% ;Below 70% unspecified.

Pulse Rate Measuring

• Measuring range:25bpm - 250bpm
• Accuracy: +/-2bpm or +/-2% (select larger)
• SpO2 is 1%; PR is 1bpm.

Measurement Performance in Weak Filling Condition

• SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is +/-4%;pulse rate error is +/-2 bpm or +/-2% (select larger).

Resistance to surrounding light

• The deviation between the value measured in the condition of man-made light or indoor natural light and that of darkroom is less than +/-1%.

Work Environment Requirement

• Environment temperature: 0°C - 50°C
• Relative humidity: 15% - 95%
• Atmospheric pressure: 700hPa - 1060hPa
