Mini Sound Meter

For calibration of all Sper Scientific digital sound meters and any sound meter with 1" or ½" microphone. Conforms to ANSI S1.4-1984 and IEC942 1988 Class 2 standards for acoustical calibrators. Simply place the calibrator on to the digital sound meter’s microphone, turn on the calibrator, and adjust the meter’s reading to either 94 or 114 dB. Comes with a carrying case, adaptors for 1/2" and 1" microphones, instructions and a 9 volt battery.

Calculates SPL and L_EQ Sper Scientific’s Integrating Sound Datalogger measures sound pressure level (SPL) according to A or C weighting and integrates the weighted SPL over an established length of time, such as an 8-hour workday, to calculate cumulative sound exposure (L_EQ). Test parameters are simultaneously displayed on a large, bright, backlit display, featuring 0.1 dB resolution and a bar graph. Up to 64,000 data records can be stored in the meter, saved, graphed, and processed on a computer through the USB interface and included software. The bidirectional USB port and software also enable control of the meter via its on-screen image. Features include SPL and L_EQ sound level readings, fast and slow time weighting, A and C frequency weightings, and over-limit and under-limit alarms. A single dynamic 30 to 130 dB range eliminates the need to manually select ranges and prevents data errors during range changes in auto-ranging models. The meter complies with IEC 61672-1 Class 2, ANSI S1.4 Type 2 standards. Calibrate in compliance with OSHA using Acoustical Calibrator 850016. Comes in a foam-lined protective carrying case, complete with a windscreen, USB computer connection cable, software, instructions, calibration tool, recorder output plug, and 4 AA batteries, which provide about 30 hours of use. The optional microphone extension cable enables remote measurements. N.I.S.T. Traceable Certificate of Calibration available. Dimensions: 10¾" × 3½" × 1½" (273 × 89 × 38 mm) Weight: 14.6 oz (414 g)

Sound Level Pen is the smallest, lightest, easiest to carry sound meter in the world. Despite its small size Sound Level Pen is a full function type 2¹ sound meter perfect for testing OSHA requirements and most other sound meter applications. Auto-ranging with simple one-button operation. Measures the 32~130 dB range in the 'A' scale, with an accuracy of ±1.5 dB. The display provides 0.1 dB resolution, under range, over range and low battery indicators. Comes ready to use with two AAA batteries, instructions, calibration tool, and a wind screen.

Meets IEC61672 and ANSI S1.4 frequency weighting and time weighting specifications for a class 1 sound meter. Covers the 30-130 dB range in both the A and C decibel frequency weighting scales with 0.1 dB resolution and an accuracy of ±1 dB (125 Hz ~ 4 kHz).Comes ready to use with a windscreen, calibration tool, instructions, and two 9V batteries, all contained in a hard shell carrying case.
