The LOOKEE A310 and A310L are essentially the same product — they share the same features, parts, and firmware. The only difference is the color:

• A310 comes in blue.
• A310L comes in black.

Both models include:

• An alarm feature that sounds when oxygen saturation (SpO₂) or heart rate (PR) goes below or above the preset threshold.
• A Perfusion Index (PI) display that indicates pulse strength.
• Ideal use for spot checking and short-term monitoring.

It measures oxygen saturation (SpO₂) and pulse rate (PR) using a fingertip sensor.

The A310 is suitable for adults and children over 3 years old. It should not be used on children below 3 years as results may be inaccurate.

No. It is a monitoring and screening tool, not for medical diagnosis or treatment decisions.

It’s suitable for home, hospital, and clinical settings (e.g., surgery, anesthesia, pediatrics, ICU, oxygen bars, sports health monitoring).

The A310 is meant for spot checks and short-term monitoring, not continuous 24-hour use.

Two AAA 1.5V alkaline batteries, providing 20+ hours of continuous operation.

• Press the power button to turn it on.
• It will auto power off if no finger is detected for more than 16 seconds.

The color OLED display shows:

• SpO₂ (%)
• Pulse Rate (bpm)
• Plethysmogram waveform
• Perfusion Index (PI)
• Low battery indicator

Yes. Hold the direction button for 1 second to enter the menu:

• Sound Reminder: On/Off
• Beep: On/Off
• Brightness: Levels 1–5
• Restore: Factory reset
• Demo Mode: On/Off

The LOOKEE A310 allows you to manually change the screen orientation so you can view your readings from different angles.

To change the orientation:

1. While the device is on and displaying readings, press and hold the direction button for about one second.
2. The display will rotate to the next viewing position.
3. Repeat the step to cycle through all available orientations until you reach your preferred one.

Parameter

• ±1 bpm
• ±1%

Possible Cause:

Your finger may not be fully inserted, or there may be poor blood circulation (low perfusion).

Solution:

Reinsert your finger completely or try a different finger. If readings are still unstable, consult your doctor for further evaluation.

Possible Cause:

Movement or hand trembling during measurement can cause unstable readings.

Solution:

Keep your hand and body still while taking measurements, and retry.

Possible Cause:

The finger might not be positioned correctly, or your actual oxygen level (SpO₂) may be low.

Solution:

Reinsert your finger properly and take another measurement. If abnormal readings persist, seek medical advice.

Possible Cause:

The batteries may be drained, incorrectly installed, or the device could be damaged.

Solution:

Replace or reinstall the batteries correctly. If the device still does not turn on, contact customer service for assistance at support@LookeeTech.com

Possible Cause:

The oximeter automatically powers off when not in use, or the battery is low.

Solution:

This is normal. If it turns off too quickly, replace the batteries.

Possible Cause:

Battery power is running low.

Solution:

Replace both AAA batteries with new ones.
