Description

The Ambco OTO-Chek Biological Test Simulator is used to measure the accuracy of your audiometer to within 5 db. This unit can be used daily, but does not serve as substitute for required yearly calibrations.

Warranty: 5 Years Defects in Materials or Workmanship.

Features

Ambco OTO-Chek Biological Test Simulator Features

  • Meets OSHA and other requirements for biological audiometer calibration checks.
  • OTO-CHEK can be used with any manual audiometer or automatics with normally open relay contacts.
  • Ready to use.
  • Response Output: Normally open relay contacts.
  • Simply place the earphones over right and left couplers of OTO-CHEK:
    • For MANUAL TESTING, turn OTO-CHEK on. Present the tones as in manual testing and record the frequency and HL when there is positive RESPONSE by OTO-CHEK, red light on. Retain these baseline results and use them to compare future tests. ESTABLISH NEW BASELINE every time the audiometer is re-calibrated.
    • For AUTOMATIC TESTING, place the earphones on OTO-CHEK, plug the response switch from OTO-CHEK to response jack on audiometer. Turn OTO-CHEK on. Turn automatic audiometer on and initiate automatic test. If printer is connected to the Audiometer, results will be printed. Retain these baseline results and use them to compare future tests. ESTABLISH NEW BASELINE every time the audiometer is re-calibrated.

Frequently asked questions

Does OTO-Chek support daily calibration checks?

Yes, the Ambco OTO-Chek is specifically designed to perform routine daily biological calibration checks on audiometers, ensuring compliance with regulatory standards like OSHA.

This diagnostic tool verifies that the audiometer’s measurements remain highly accurate:

  • Accuracy Tolerance: It confirms results are within +/- 5 dB of the established baseline reading.
  • Frequency Coverage: It covers a full range of test frequencies, from 125 Hz up to 8000 Hz.

It is important to note that while the OTO-Chek is essential for daily verification, it is not a substitute for the mandatory yearly professional electronic calibration.

Is the OTO-Chek fully compliant with OSHA?

Yes, the Ambco OTO-Chek Biological Test Simulator is designed specifically to meet OSHA and other regulatory requirements for routine biological audiometer calibration checks.

Key details regarding compliance:

  • It satisfies the need for daily biological checks, ensuring measurements are within a 5 dB tolerance.
  • It does not substitute for the mandatory yearly electronic calibrations.
Which audiometers are compatible with OTO-Chek?

The Ambco OTO-Chek Biological Test Simulator offers broad compatibility, working with two main types of audiometers:

  • Any manual audiometer
