Introduction Sound Level Meter model TM-100 of Tenmars

The Tenmars TM-100 Sound Level Meter Calibrator is a hand-held device that emits an audible tone of very accurate level and frequency. Before making sound level measurements the Calibrator is fitted over the meter’s microphone and the reading is either checked manually by the user or automatically by the meter.

Checking a meter’s calibration is good practice and for many applications it is essential. Most regulations demand that the meter is verified before making measurements. Records should be kept of this as evidence that the correct procedures have been followed.

A Calibrator should meet the standard IEC 60942 to either Class 1 or Class 2. The Class 1 calibrator is a little more accurate than the Class 2. In general, if you have a Class 1 (or Type 1) Sound Level Meter then you should use a Class 1 Calibrator. If you have a Class 2 Sound Level Meter you can use either a Class 2 or Class 1 Calibrator.

The Tenmars TM-100 is a Class 2 Sound Level Meter Calibrator for calibrating sound level meters at 94dB & 114dB & come with a 1/2 inch microphone adapter.
