POLAR FT4
The Polar FT4 sports tester includes a wrist receiver (watch), a wearlink strap, a Slovak manual and a wearlink transmitter.
The most important advantages:
- coded digital transmission of SF heart rate - limits mutual interference when a large number of people are measured at the same time
- individual setting of the optimal SF heart rate zone during exercise (upper and lower limit)
- calculation of Energy expenditure in calories, including the percentage of fat burned and long-term records
Measurement functions:
- wireless transmission of SF heart rate signal based on continuous measurement with ECG accuracy (Wearlink transmitter with replaceable battery)
- current heart rate SF (beats per minute or % of maximum SF)
- visual signaling of the energy cover source indicator
- stopwatch (no option to save intermediate times)
- caloric expenditure during measurement
- possibility to change settings during measurement
Memory functions:
- it is possible to store up to 10 recent records containing the following data: measurement date, exercise duration, energy expenditure, average and maximum SF during exercise, time spent in the set zone
- at the same time, the device has weekly and long-term counters of the following parameters: total number of exercises, total energy expenditure, total exercise time
Other functions:
- display backlight
- watch with daily date, alarm clock
- choice of device control language (English, German, French, Spanish, Italian, Portuguese, Finnish, Swedish)
- waterproof for rain, showering (designation "30m" according to ISO2281 standard)
