【Product Specifications】 Display Mode: LCD liquid crystal display Measurement Method: oscillometric detection method Measurement Range: Pressure: 0~280mmHg Pulse Rate: 40 beats/min ~ 199 beats/min Accuracy: Pressure: ±3 mmHg Pulse: ±5% Power Supply: DC6V Normal Working Environment: Temperature 5~40℃ Humidity≤80%RH Transport and Storage Environment: temperature -20~55℃, humidity 10%~90%RH Measurable Arm Circumference: approx. 22cm ~ 32cm Safety Classification: Internal power supply type B Pressurization Method: vibrating wing pump pressurization adjustment method Rapid Exhaust Method: ultra-fast exhaust valve opening method Pressure Detection: semiconductor pressure sensor Pulse Detection: Semiconductor pressure sensor 【New Temperature Control Sensor】Technical innovation, by adding a temperature control sensor to the blood pressure monitor, the temperature control sensor measures the actual temperature, compares it with the working temperature of the blood pressure monitor, and compensates the measurement results to ensure the performance and accuracy of the blood pressure monitor. [Uses Imported Chips] In terms of material selection, imported chips are used. New imported products are technically incomparable to domestic chips, providing a hardware basis for the accuracy of the electronic blood pressure monitor. 【Simple, Fast, and Accurate】Make blood pressure measurement easy and convenient with increasingly accurate measurements and powerful algorithms. 【Note】: 1. All measurements are measured by hand, with an error of 1-3 cm; 8. Due to the difference between camera light and display, there will be a slight color difference. *Everything in kind prevails!
