Description

Diagnostic Audiometer CCLAD100 (With built-in Lithium battery)
★ Ideal for hearing screening work in schools, medical centers, hospitals or enterprises.
★ Stylish appearance design, compact and lightweight, portable and convenient,
built-in battery.
★ Test function: air conduction (AC), bone conduction (BC).
★ With built-in microphone or external goose neck microphone (optional),
easy to communicate with the tester.
★With standard USB 2.0 data interface, the audiometry data can be saved after connecting to the workstation. According to the National Occupational Health Standard of the People's Republic of China, it can analyze and generate a professional noise diagnosis report.
★ Custom report Logo and name can be set through the workstation, and A4 or B5 format report can also be generated.

Technical Specification

Channels: Two independent output channels
Air conduction:
1. Frequency: 125Hz~8000Hz;
2. Hearing level: -10~110Db.
Bone Conduction:
1. Frequency: 250Hz~6000Hz.
2. Hearing level:-10~60dB
Minimum hearing level: The minimum hearing level should be -10dB for pure-tone audiometer of Class 1 and Class 3.
Frequency accuracy: The allowable error of frequency for this audiometer is ±2%.
The accuracy of audiometer controller: Step of the audiometer controller should be ≤5dB; the deviation of the indication difference between two adjacent hearing levels should be ≤3/10 or 1 dB of the step. Adopt the smaller value.
Masking Noise Level Range: The masking noise of the audiometer should be able to mask pure tone of at least 60dB at 250Hz, 75dB at 500 Hz, 80dB at 1000Hz～4000Hz. The masking noise level should be adjustable within the range from 0dB to the above level.
The accuracy of masking noise level : The allowable error of the masking noise level should be -3dB~+5dB.
The accuracy of masking noise level controller: The step of the masking noise level controller should be ≤5dB. The deviation of the indication difference between two adjacent hearing levels should be ≤ 3/10 or 1 dB of the step. Adopt the smaller value.
When the unwanted sound radiated by pure tone audiometer is >50dB HL, people with normal hearing should not hear any unwanted sound radiated by the pure tone audiometer.
Protection Function: Protect the tester’s hearing from damage as much as possible
Computer interface: USB 2.0 data transmission interface, can be connected to the workstation for printing test report
