I RECOMMEND!✓ http://ali.pub/vgral (Tonometer with DC Power Supply)
Other Devices: http://ali.pub/bjlak
Overview tonometer an instrument for measuring blood pressure. When transporting the box a little wrinkled, but the contents are not affected. Good workmanship. Plastic odorless. The cuff is straight, which is not very convenient, especially for full hands. Have fastened diagonally. But it does not affect the measurement. In most cases, the standard cuff size is enough (2232 cm), but if you want more (2248), then report it to the seller. There are versions tonometer with light and sound.
Meryl imagine the pressure 3 times:
1) 122/66 74
After the first measurement drank chicory (as if), which has reduced the pressure by about 20 units.
2) 105/62 74
3) 102/64 70
The discrepancy between 2 and 3, the minimum dimension. The instrument measures the everything exactly. Good quality / price ratio. I recommend to buy!
