New wristwatch-type pulse monitor

Japan Precision Instruments will release a wristwatch-type pulse monitor at mass retailers nationwide from early April. Three models are available: the "HR-60" that records measurement data only on this unit, the "HR-70" that works with a computer, and the "HR-80" that works with a smartphone. The price is an open price. Expected store prices are 12,800-14,800 yen, 17,800-19,800 yen, and 22,800-24,800 yen. The HR-80 is scheduled to go on sale after July.

A wristwatch type pulse monitor. The feature is that it is integrated with a sensor that measures the pulse with a finger so that the pulse can be measured while exercising such as jogging or walking. By checking the intensity of your exercise based on your pulse rate, you can find out the optimal training intensity for you, allowing you to safely and efficiently perform aerobic exercise. As users, we assume people in their 40s to 60s who regularly do aerobic exercise, people who are highly health-conscious, and athletes.

The body color is available in black and gray for each part number. Measurement sensor to be worn on the index finger on the back of the body

To install, wrap the device around your arm like a wristwatch and insert your index finger into the sensor. Compared to conventional heart rate monitors that attach a belt to the chest, it has the advantage of being easier to use.

Wrap the belt around your arm first. The belt can be removed and washed. A sensor that fits a woman's thin wrist is firmly inserted into the back of the index finger. The palm side has a good fit and does not come off even when you move your fingers. Unevenness is kept to a minimum

During measurement, the pulse is displayed numerically on the LCD screen, and the exercise intensity is displayed in the color and graph of the backlight. The backlight is green for light exercise, yellow for optimal aerobic exercise, and red for intense exercise like anaerobic exercise. This allows you to check your exercise intensity in real time.

The backlight color is green yellow red. The difference in color is clearly visible, and the exercise status is displayed with the color of the backlight and the graph on the screen

Enter your age and gender in advance when using. In addition to pulse, the measurement items include calorie consumption, fat consumption, exercise intensity, exercise time, and lap time. It also has a clock display function, so it can be used as a wristwatch in normal times. There is no lap time memory function.

When the wrist is tilted to the viewing angle of the watch, the backlight of the LCD screen automatically turns on during measurement. The basic screen displays the current time and pulse rate. When you press the "MODE" button on the side of the main unit, the "exercise recording time" that indicates the elapsed time since the start of measurement is displayed in the upper row, and the exercise intensity is displayed in the lower row. When you press the " button, the calorie consumption is displayed in the upper row and the amount of fat consumed in the lower row. The photoelectric method uses the light-absorbing properties of blood to emit a certain amount of light from a light-emitting element and measures the amount of light reflected, thereby measuring blood volume that changes with pulsation. Since the fluctuation period of the reflected light and the pulsation period of the blood are the same, it is displayed as the pulse rate using a unique algorithm.

The photoelectric method is a measurement method that utilizes the characteristic of blood that absorbs light. The exercise intensity is calculated using the expression based on the reserve pulse rate (%HRR). Even people of the same age and sex have individual differences in their resting pulse rate and exercise pulse rate. By determining the exercise intensity based on these values, it is possible to obtain results that are more personalized.

The power supply is equipped with a 140mAh capacity lithium-ion battery, which takes 2 hours to charge and can be continuously measured. About 10 hours. If you use only the clock display without using the measurement function, you can use it for about a week with one charge. Use a Micro USB cable for charging.

In terms of maintenance, the parts around the sensor attached to the finger and the wristwatch-shaped belt can be removed and washed with water.

After removing the parts around the sensor that fits on the finger, the charging port on the side of the sensor. The HR-70, which comes with a rubber lid, can manage data on a computer.

As a linking function with other devices, the HR-70 can be connected to a computer via USB to save measured data. , can be graphed and managed. The HR-80 manages measurement data by linking with various smartphones via Bluetooth communication.

The body size is 43.6 x 62.3 x 22.2 mm (width x depth x thickness, excluding the band). The main body weight is about 50g. The waterproof standard corresponds to IPX4 life waterproof. The measurement range is a pulse rate of 30 to 238 beats/minute, a maximum exercise recording time of 9 hours and 59 minutes, a maximum of 9,999 kcal of calories burned, and a maximum of 999 g of fat consumed. The colors are black and gray.
