| B&K 2250 RT Reverberation Time Meter - with BZ 7227 software | £ 31 a day * |
The Reverberation Time Software BZ-7227 extends the easy to use Hand-held Analyzer Type 2250 to include Reverberation Time (RT) option for architectural and room acoustics measurements.Press the Start/Pause push button, clap your hands and that's all it takes to do a basic measurement. The traffic lights shows measurement status at a glance, and the resulting RT spectrum is shown as well as the average RT, reverberation time for the room.
Keep track of measurement positions in the colour map display, check the indicators for measurement quality, and add spoken or text comments to positions or projects.
Measurements comply with the relevant parts of ISO 3382 and British Standards.
Type 2250 is the innovative 4th generation hand-held analyzer and comes fully equipped as a sound level meter with PC software for data transfer.
