【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Anyone can use it with confidence. The high-resolution system has made it possible to identify intervals of pulse wave disturbances better than ever before. High Resolution System HiRS (High Resolution System) is a high-precision pulse wave interval measurement system that acquires six times the amount of data during measurement compared to conventional NISSEI products. It is now possible to identify intervals of pulse wave disturbances better than ever. Easy to read - Individual display that shows measurement results in large letters - WHO blood pressure classification display that allows you to see trends at a glance Easy to use - Easy-to-wrap "perfect cuff" - Memory function for two people - Automatically sort morning and night records Accuracy Equipped with new engine "HiRS"
