Test Meter PRO TMP1345 Mini Sound Level Meter The TMP1345 Mini Sound Level Meter is light and easy to use. The Test Meter PRO Sound Level Meter's measuring range is 30 to 130 dB with frequency response for A and C weightings for human sense or machine monitoring purposes, which meets IEC 61672. It measures sound levels in dB (Decibels) on a large digital display. This extremely versatile sound test meter is ideal for measuring sound levels in most acoustic environments, it's even good for novices. They have been used for testing fire alarm sound levels in buildings, offices, schools, colleges, small businesses and shops. The Test Meter PRO TMP1345 Sound Level Meter can check sound levels/noise in large areas, loud or attenuated, treble or bass, intermittent or continuous. Use "A" for human ear bias (500 - 10000Hz) or "C" for the full frequency range (32 - 10000Hz). This digital sound level test meter has a switch to select fast or slow time ratings making peak and average readings easier to assess. Another benefit is the Data Max and hold functions. The UK Noise at Work Regulations, 1990, require employers to provide suitable ear protection when noise levels can rise between 85db and 90dB. If noise levels rise above 90dB then ear protection must be supplied and worn. High noise levels can cause irreversible damage to the tiny sensory hairs in the ear over a period of time. Noise is measured in decibels and an increase of 3 decibels doubles the noise level.
