Simpson - Sound Pressure Level Meter & Calibrator MODEL: 884 TYPE: S2A / MODEL: 890 Simpson - Sound Pressure Level Meter & Calibrator Simpson 884 - Sound Pressure Level Meter Simpson 890 - Sound Pressure Level Calibrator Simpson 884 - Simpson's sound level meters come in three different versions to handle virtually any noise measurement requirement: Model 884-2 with an "A" weighted scale for simple measurements, Model 886-2 with a choice of fast or slow response and "A", "B" or "C" weighting, and Model 899 impulse meter for quick bursts of sound. All three models have output jacks for connecting to the Simpson 606 Flatbed Chart Recorder or other chart recorders. Optional calibrators are available for in-field adjustment. The optional 898 octave band filter allows measurement in narrow frequency bands to isolate specific noises. Simpson 890 - Sound pressure level calibrators are essential accessories to be used before or after taking measurements with sound level meters and noise dosimeters. The 890-2 can be used to adjust Simpson models 886-2 and 884-2, and other sound level meters with a 1" diameter Microphone. The 890-2 provides a constant 94 dB or 114 dB sound pressure level at 1 KHz (0 dB = 0.0002 Mbar).. All Simpson Calibrators are immune to a wide range of temperature and humidity conditions while maintaining tight output level tolerances. 3" X 8.2" X 1.9" (inches WxHxD) * General Purpose Type 2 Meters for OSHA and Laboratory Sound Measurements * Full Coverage From 40-140dB with Special 85-115dB OSHA Range * A - B and C Weighted Measurement Options * Rugged Solid-state Reliability Battery-operated * Impact-resistant Case Contoured to Minimize So * For use with Simpson 884/886 Model Sound Meters Excellent (Item shows very little signs use / wear) Excellent (Item has been tested - Functions 100%) Operator's Manual, Original Warranty Card - (PDF Manuals can also be downloaded) 3.0" x 8.2" x 1.9" (77 x 208 x 47mm) A,B,C, (external filter for flat response) condenser type L size per ANSI S1.12-1967 Omnidirectional, angle of incidence approximates random response equal to 70° 120mV RMS at meter reading of +10dB 1.00V RMS at meter reading of + 10dB 1.5 VDC at meter reading of + 10dB frequency=1000Hz@94dB on the 90 dB range, 114 dB on the 110 dB range.
