Voice coil thermometer capable of measuring 5 speakers simultaneously.
The OMT-405 is a thermometer that measures the temperature of the voice coils built into a 5-channel speaker unit. It can measure five speakers simultaneously and responds to various sources (sine waves, white noise, pink noise, standard load test noise, music sources) in the frequency range of 20Hz to 20kHz. It displays graphs and values of temperature and input voltage over time. 【Features】 ■ Data sampling can be selected from 1 second, 10 seconds, or 60 seconds ■ Measurement time can be set from 1 minute to 100 hours, in 1-minute increments ■ Stop temperature setting (forced measurement termination) can be set from -50°C to 400°C, in 1°C increments ■ Operating modes include "All Mode," where the set channels operate simultaneously, and "Single Mode," where individual channels start operating independently *For more details, please download the PDF or feel free to contact us.
