Take reliable noise readings on site with a portable meter that fits the hand well. ATP ET-958 Data Logging Sound Level Meter records levels and keeps the data ready for checks back at the desk. You move through tasks with simple buttons and clear on-screen prompts. The bargraph helps you see trends at a glance.
Fast setup and clear control
You set A or C frequency weighting for the rules you follow, then choose fast or slow timing for the job in front of you. The 55 mm backlit display stays readable in plant rooms and low light areas. Max and Min help you capture peaks and lulls without missing a moment.
Flexible logging for site work
You can log long sessions or quick spot tests with intervals from one second to long gaps. Real time transfer over USB helps you view results on a PC as they happen. A tripod thread keeps the meter steady when you need stable capture outdoors or near machinery.
The instrument meets the accuracy target of IEC 61672 at ±1.4 dB on the stated check points. It covers quiet areas and loud environments with four ranges and an auto option. You keep going with battery power and you can use the mains adaptor when needed. As a result you can survey many locations in one visit.
