From noisy nightclubs to loud manufacturing facilities, Extech decibel meters are used around the world to test whether a sound level exceeds levels established by municipal or national laws. Occupational safety and health standards turn to Extech for a reliable sound meter (commonly called a dB meter or noise meter) to determine an acceptable noise level with and without hearing protection. For on-the-person occupational sound measurement, Extech’s noise dosimeter selection offers options for datalogging personal exposure to excessive sound levels.

Commonly used in noise pollution studies for the quantification of almost any noise, the sound level meter measures sound pressure level. Especially for industrial, environmental and aircraft noise, this meter is the most appropriate and accurate one. As a leading Taiwanese manufactures of high quality test and measurements, our sound level meter performance is conformed to the international standard, IEC61672:2003.

Our tightening assurance system eliminates various mistakes that occur during bolt tightening operations, and it even advises users how to perform tightening operations properly.

This is what one of our satisfied manufacturing customer claims two and a half years after beginning a Tohnichi’s tightening assurance system. The system has reduced human tightening errors in our factory to zero and has ensured proper control over all torque operations. Tohnichi’s products are a requirement to prevent a wide range of problems.
