Traceable® Sound Level Meter
By Control
Three-decibel ranges
Features three-decibel ranges for greater precision: low (30.0 to 80.0 dB), medium (50.0 to 100.0 dB), and high (80.0 to 130.0 dB). Resolution is 0.1 dB and accuracy is 1.6%. Unit provides weightings for both A (frequencies for 500 to 10 kilohertz) and C (frequencies from 30 to 10 kilohertz) to meet IEC 651 Type-2 standards.
Adjustable response time
Response time may be set to fast (0.2 seconds) or slow (1.5 seconds). A handy memory data-hold function stores the highest reading achieved for later display. Ideal for fulfilling OSHA requirements. Unit uses a 1/2-inch condenser microphone. A recorder jack permits capturing readings (AC and DC 10 mV/dB).
