Name: Precision Blood Pressure Monitor

Model: BXY-250

Pressure: 0-40KPA

Accuracy: 0.25 level, 0.16 level

Purpose: Used for verifying ordinary mercury sphygmomanometers and as a standard device for sphygmomanometers. Precision sphygmomanometer, as a standard instrument, is one of the essential instruments used in hospitals and metrology for general inspection. BXY250 precision blood pressure monitor with skin bag compression is a simple but very practical calibration device.

introduce
Desktop precision blood pressure monitors are mainly used for precise measurement of human blood pressure and for detecting single tube mercury column blood pressure monitors and blood pressure gauges.

Verification method
If there are doubts about the accuracy of the blood pressure monitor, an accurate mercury column blood pressure monitor or blood pressure monitor can be used to calibrate it together. The method is to remove the "Y" - shaped tube from the stethoscope, and connect an accurate blood pressure monitor (sphygmomanometer) and a calibrated spring type sphygmomanometer at both ends. The third end is connected to an arm strap and an air valve. Using the same pressure, observe whether the readings of the blood pressure monitor to be calibrated and the accurate blood pressure monitor (sphygmomanometer) are consistent. If they are different, it means that the calibrated blood pressure monitor is no longer accurate. If the readings are the same and there is only a deviation in the zero position, it does not affect actual use. If the pointer of the blood pressure gauge cannot return to zero position, do not adjust the screw without authorization to avoid damaging the movement inside the gauge. At this time, the blood pressure gauge should be sent to the manufacturer or designated service department for repair.

Technical Parameter
Model: BXY-250
Pressure range: 0-40KPa
Accuracy level: 0.25 level, 0.16 level

precautions
Before using a spring type blood pressure monitor, it should be checked first. A blood pressure monitor that can be used normally should have the dial pointer pointing to zero. After pressurization, the response should be flexible and still return to the original zero position.
