2 OVERVIEW
Through the broading market investigation, our company assembles a lot
of talents in the following majors: the appearance design of the product,
structure design, transmission structure design, and circuit design, they
produced ECG successfully after their deep research and reduplicate tests.
This equipment adopts the thermal recording mode (the key point of thermal
recordingtechniqueisthecorecomponent---thermalrecordingprobe.
Thethermalrecordingprobeisthehigh-techcomponentwithadvanced
component integrated technology, integrating a large amount of heating
elements (8points/millimetre) and its controlled circuit based on the ceramic
basalbody.Itdoesn’thavethefalsedifferencewhichcausedbynon-
