Graphic Display 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.

This unique Sound Meter enables remote sound level readings using a detachable probe. Features both RS232 computer interface and AC output. Also has A and C decibel frequency weighting scales, fast or slow time weighting, hold, peak hold, and min-max functions. Meets IEC651 and ANSI S1.4 specifications for a Type 2 sound meter. Covers 30~130 dB in both Manual and Auto ranging scales with 0.1 dB resolution and an accuracy of ±1.5 dB. Comes ready to use with a windscreen, calibration tool, instructions and 9V battery in a hard-shell foam-lined carrying case. Coiled probe extends to 9'.

This tiny meter is packed with features, yet its small and light enough to be carried in your shirt pocket. Choose from fast or slow time weightings, min-max readings and A or C decibel frequency weighting scales. All of these settings are simultaneously displayed on a large 1¼" backlit display. Also features hold, and auto-power off. Readings are extremely stable and reliable. Meets IEC651 and ANSI S1.4 specifications for a type 2 sound meter. Auto-ranging 30 -130 dB(A) with 0.1 dB resolution and an accuracy of ±1.5 dB (Ref. [email protected]). Can be calibrated, in compliance with OSHA, using Acoustical Calibrator 850016 or equivalent. Comes ready to use with a windscreen, instructions and 9V 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)
