SOUND METER TRACEABLE ,Each

Details

This Traceable sound level meter features three decibel ranges for greater precision: low (30-80 dB), medium (50-100 dB), and high (80-130 dB). The resolution is 0.1 dB, with an accuracy of ±2 dB. The device measures 7.6 x 25.4 x 2.5 cm (3 x 10 x 1 inch) and weighs 269 g (9.5 oz.). It records sound levels together with decibel readings and has an adjustable response time that can be set to fast (0.2 seconds) or slow (1.5 seconds). A memory data-hold function stores the highest reading achieved for later display. The meter uses a 1.3 cm (0.5 inch) condenser microphone and features a recorder jack that captures readings in both AC and DC modes, with an output of 10mV/dB. It provides weightings for both A (frequencies from 500 to 10kHz) and C (frequencies from 30 to 10kHz), meeting IEC 651 Type-2 standards. The device comes with a serial-numbered certificate from an ISO 17025 calibration laboratory, indicating instrument traceability to standards provided by the National Institute of Standards and Technology. It is supplied with a 9V alkaline battery and carrying case.
