Dual-user blood-pressure monitor

The Invaxe AOJ-30G is an automatic upper-arm blood-pressure monitor designed for home use. It stores 199 readings for each of two users and calculates the average of the last three measurements. A 4.5-inch backlit LCD with large numbers and a 45-degree curved angle improves readability. The adjustable cuff fits arm circumferences from 9 to 17 inches.

Replaces manual logging and single-user devices

This monitor removes the need to write down every reading by keeping 199 records per person. The three-reading average gives a more stable picture than a single snapshot. The jump is worth it when two people share one device or when long-term trend tracking matters for hypertension management.

Suits households monitoring two adults

The dual-memory layout and large cuff serve couples or caregivers tracking two users. The USB and AAA-battery power options support home, office or travel use. Buyers who need clinical validation data, smartphone connectivity or a cuff larger than 17 inches should look at other models.

Questions about this item

What arm circumferences does the 9–17 inch cuff fit?

The cuff adjusts from 9 to 17 inches, covering most adult arms. Wrap it snugly two centimetres above the elbow with the tube centred on the inner arm.

How do I install the batteries and avoid the common polarity mistake?

Insert the four included AAA cells matching the + and – symbols inside the compartment; the spring contact is negative. Reversing them prevents power-up.

When should I replace the cuff or batteries for reliable readings?

Replace the four AAA batteries when the low-power icon appears. Swap the cuff if the fabric frays, the bladder leaks air, or the Velcro no longer holds securely.
