Easy to learn
The easy operation of the eddyMax-Control in-service tube inspection system is ensured by the field approved components and the user friendly menu- and function-key-controlled software, which are permanently improved by our operators.
Multi-frequency digital eddy current instrument
The eddyMax- Control is designed for fast in-service tube inspection. With this portable system a lot of advantages are brought to heat exchanger inspection activities.
High Detection Capacity
Detection of wall thinning as the result of erosion, corrosion, wear, pitting, cracks and baffle cuts.

Inspection of NFe and Fe Tubing
Inspection of non-ferromagnetic and ferromagnetic tubing in petrochemical, chemical and power generation plants.
Easy Parameter Setting
All parameter settings and configurations are done from the keyboard and can be individally stored and retrieved from hard or flexible disk.

Computer Controlled Probe Handling
Complete remote operated computer controlled probe handling beginning with the HPP2.V3 probe push-puller system up to a 3 axis manipulator system can be optionally included in the system.
Manipulator Control
Inspection of tubing in high radiation or contaminated areas by fully automated remote controlled manipulator system.

Data Recording
Raw eddy current data is recorded as x- and y- components of each channel on hard disk. Intelligent data reduction algorithms ensures maximum use of storage capacity. For permanent storage the signals can be written to an optional installed optical disk drive.

Coloured real-time display
Coloured real-time display of x-y impedance plane and/or strip chart signals selectable from up to 4 signal channels and several independent mixer channels. Each channel may be assigned to any window, whereby in each window all available channels may be displayed at the same time.

Multi Mix Module
The innovative multi mix module with free adjustable mixer channels allows very effective suppression of noise and disturbing signals e.g. baffle plate signals. Due to the automatic mix function the mixer is set within seconds by pressing only a single key.
Protocol Function
This function allows the output of the actual impedance plane image including instrument settings for documentation purposes.

Signal Analysis Software
The automatic signal analysing software module allows defect depth evaluation of differential signals either online during inspection or offline from stored signals. The data from up to 1000 defect signals per tube will be evaluated and stored directly.
Calibration Curve Generation
The generation of calibration curves, the signal phase setting and phase grid display is done according to ASME-code or user defined requirements.


WINDEVOS Data Documentation Software
The powerful WINDEVOS data documentation software provides the perfect planning and result presentation of heat exchanger tube inspections under Windows. Several documentation works like graphic tube sheet map generation, report output, automatic plugging map calculation and output, statistics and automatic display of defect evolution are done by this software. The extended color and marking option menu allows customized result

Inspection accessories
By a great number of probes for different inspection tasks, rotors for tubes and boreholes, software modules and other accessories the eddyMax-Control can be adapted to different inspection tasks in an optimal way and enables the user to fulfill a great variety of inspection
