1.Adopt the III dual-frequency measure technology, display with large LCD.
2.Measuring will not be effected by environment, no matter the root is dry or full of electrolyte(blood, or normal saline), it can measure precisely.
3.Manify the apex zone, display with 11 scales, precision can reach 0.1mm.
4.Number and scales display the detecting position synchronously.
5.With sonar alarm when it in narrow zone, and the sonar volume can by regulated.
6.Auto-check when starts up, calibrate the data previously, remain the operation precision.
7.The narrow zone of apex can be regulated by the doctor if it needed.
8.Long power consumption design, super long using time, power supplied by No.7 battery, with 7 scales battery indication.
9.The accessories can be sterilized with high temperature, prevent the patients from cross infection.
