TA650A Digital Sound Level Meter 30-130 dB Portable

The TA650A Digital Sound Level Meter is a portable, high-precision tool designed to simplify noise assessment in any environment. With a measurement range of 30.0 to 130 dBA and an accuracy of ±1.5 dB, this compact meter delivers reliable data for workplace safety, construction sites, studios, classrooms, and field inspections. Its highly sensitive 1/2" capacitive microphone provides fast, accurate responses to changing sound levels while maintaining smooth measurements across a broad frequency range (31.5 Hz to 8 kHz) with A-weighting for real-world comfort and safety standards. Readability is boosted by a large HD display with a white backlight, making it easy to capture readings in low-light conditions. The TA650A also offers MAX/MIN locks to capture peak and trough levels, and a FAST/SLOW time weighting option to suit rapid transient noises or steady ambient sounds. Portable and simple to use, it’s ideal for professionals and enthusiasts who need quick, dependable noise measurements on the go.

Benefits & Tips

• Document safety levels—Use MAX/MIN to record the highest and lowest noise levels over a period to document safe or unsafe environments.
• Tailor readings to noise type—Switch between FAST and SLOW time weighting to match fast transient noises or steady background sound.
• Read clearly in any light—Take advantage of the backlit display to read measurements clearly in dim conditions or at night during on-site inspections or studio work.
