LT0702 tachometer audiometer sonometer
Several yards electric measuring devices are described by sound
LT0702 digital electronic detector is more functional modules of computerized listening test equipment, mainly based on hearing test and the occasion required by the acoustics, digital technology, combined with the advanced CeTing occasion and technical development of microcomputer auditory assessment tools.
LT0702 digital electronic detector test, suitable for pure hospital ENT (ear-nose-throat) diagnosis and occasion, and clinical, family and determination of liquidity hearing.
The test TDH39 through air guiding headset (AC). Built-in test signal is pure, pulse, and broadband noise coronas.
0702 digital electronic detector LT - provides 11 gas (AC) test frequency, the frequency range from 125Hz to 8KHz, listening to 110dBHL from 0dBHL level.
All testing data automatically converts as pure and listen to be calculated value of PTA patients.
Simple operation of the system, the bright LED, LCD display against real speaker, frequency and each other information channels. Using advanced microprocessor technology, make use of 0702 LT - more convenient and more reliable.
Hearing of structure design of automatic test procedures, convenient in maintenance is very convenient troubleshooting and annual calibration.
