Product Summary

 OMT-205A is designed to measure the temperature of the speaker voice coil while in operation.
Measurement can follow the signal source of sine waves, white noise, pink noise, or music source in the frequency range from 20 Hz to 20 kHz. The measured temperature and the input voltage are simultaneously displayed on digital displays. Two DC output terminals are prepared to record the temperature and the input voltage simultaneously.

Optional unit : Data Recorder Model OT-1009
