Petroleum And Petrochemical Industry Defect Signal Processing
Portable Magnetic Flux Leakage Detector | Model | HEF-MFL702 | | | Name | Portable Magnetic Flux Leakage Detector | | Type | Magnetic Flux Leakage | | Description | HEF-MFL702 is a multi-functional intelligent magnetic flux leakage
detector which adopts the latest dual-core 32-bit microprocessor
and DSP signal processor. The reliable testing results depend on the experienced operators
who in turn ask for best testing equipment. The HEF-MFL702 is
designed according to the operator’s need to achieve optimal
performance. The light weight, unique keypad controls, easy
programming and color large-screen LCD display, all contributes to
the reduction of detect fatigue to a minimum. Thus u are no longer
required to focus on the small and blurred images or delayed
display of large electronic transmission devices. The testing instrument with One-click menu, humanized interface,
and compact design with light-weight and applicable to various
operating conditions is the idea choice of field engineers. And
equipped with the lithium battery, the instrument can keep
operating for up to 8 hours continuously. | | Specification | 1.Multi-channel detection capability 2. Fast electronic digital balance
