Local test and measurement company, TANDM, has introduced the Brüel & Kjaer wireless smartphone operated 2245 and 2255 sound level meters to the South African market.

The ICASA approved advanced class 1 measurement solutions can be used as a stand-alone sound level meter (SLM), or paired with dedicated mobile apps, and PC software. These devices feature an open API interface, real-time remote control, device configuration, and the streaming of live measurement data and audio.

The B&K 2245 sound level meter is available in five versions, with features that simplify the measurement of exhaust noise, environmental noise, workplace noise, and product noise, while the B&K 2255 offers the added benefit of acoustics assessments like building acoustics.

Both instruments are supported by a range of apps tailored to specific tasks and offer an optional smart docking station that automatically transfers stored data to a network. The calibrator auto-detection function provides rapid and error-free calibration, giving users peace of mind when it comes to accuracy. Other key features include the single measurement range of 22.7–140.6dB(A) from noise floor to maximum level, and frequency range of 6Hz–20kHz, as well as 16GB of internal storage.

“Very few entry-level SLMs offer this wide range of capabilities with such ease of use, so it’s great to offer the local industry a best-in-class product.” says Elton Murison, Director of TANDM.
